125-457: Chinna Creek ( Urdu : چنا کریک ) is a lagoon , within the municipal boundaries of Karachi , on the coastline of the Arabian Sea , located in the south-west region of Sindh , Pakistan . Covering an area of approximately 6 square kilometres , it extends approximately 5.0 kilometres in length and spans between 300 and 500 metres in width, with depths ranging from 1 to 3 metres. Positioned at

250-633: A dialect continuum ranging from Persianised to Sanskritised vocabulary, but now they are more and more different in words due to politics. Old Urdu dictionaries also contain most of the Sanskrit words now present in Hindi. Mutual intelligibility decreases in literary and specialised contexts that rely on academic or technical vocabulary. In a longer conversation, differences in formal vocabulary and pronunciation of some Urdu phonemes are noticeable, though many native Hindi speakers also pronounce these phonemes. At

375-406: A core vocabulary of native Sanskrit and Prakrit derived words and a significant number of Arabic and Persian loanwords, with a consensus of linguists considering them to be two standardised forms of the same language and consider the differences to be sociolinguistic ; a few classify them separately. The two languages are often considered to be a single language (Hindustani or Hindi-Urdu) on

500-519: A diverse array of toxic pollutants originating from both domestic and industrial sources, posing significant risks to marine life and ecosystem integrity. The absence of robust environmental regulations and the prevalence of illegal waste disposal practices further exacerbate the pollution burden on Chinna Creek. These factors hinder the creek's ability to maintain a natural and untouched appearance, impeding efforts to mitigate environmental degradation and restore ecological balance . In 2018, although

625-537: A heavy influence on both as a co-official language. According to Bruce (2021), Urdu has adapted English words since the eighteenth century. A movement towards the hyper-Persianisation of an Urdu emerged in Pakistan since its independence in 1947 which is "as artificial as" the hyper-Sanskritised Hindi that has emerged in India; hyper-Persianisation of Urdu was prompted in part by the increasing Sanskritisation of Hindi. However,

750-507: A literary medium for Indian writers from the Bombay Presidency, Bengal, Orissa Province, and Tamil Nadu as well. As Urdu and Hindi became means of religious and social construction for Muslims and Hindus respectively, each register developed its own script. According to Islamic tradition, Arabic , the language of Muhammad and the Qur'an , holds spiritual significance and power. Because Urdu

875-581: A marine ecosystem can be measured in several ways. Measurements pertaining to zooplankton biodiversity and species composition , zooplankton biomass, water-column structure, photosynthetically active radiation, transparency, chlorophyll-a, nitrate, and primary production are used to assess changes in LME productivity and potential fisheries yield. Sensors attached to the bottom of ships or deployed on floats can measure these metrics and be used to quantitatively describe changes in productivity alongside physical changes in

1000-577: A notable novel being Umrao Jaan Ada . According to the Navadirul Alfaz by Khan-i Arzu, the "Zaban-e Urdu-e Shahi" [language of the Imperial Camp] had attained special importance in the time of Alamgir ". By the end of the reign of Aurangzeb in the early 1700s, the common language around Delhi began to be referred to as Zaban-e-Urdu , a name derived from the Turkic word ordu (army) or orda and

1125-692: A phonological level, speakers of both languages are frequently aware of the Perso-Arabic or Sanskrit origins of their word choice, which affects the pronunciation of those words. Urdu speakers will often insert vowels to break up consonant clusters found in words of Sanskritic origin, but will pronounce them correctly in Arabic and Persian loanwords. As a result of religious nationalism since the partition of British India and continued communal tensions, native speakers of both Hindi and Urdu frequently assert that they are distinct languages. The grammar of Hindi and Urdu

1250-573: A policy continued by the Mughal Empire , which extended over most of northern South Asia from the 16th to 18th centuries and cemented Persian influence on Hindustani. Urdu was patronised by the Nawab of Awadh and in Lucknow , the language was refined, being not only spoken in the court, but by the common people in the city—both Hindus and Muslims; the city of Lucknow gave birth to Urdu prose literature, with

1375-498: A sectarian divide of "Urdu" for Muslims and "Hindi" for Hindus, a divide that was formalised with the partition of colonial India into the Dominion of India and the Dominion of Pakistan after independence (though there are Hindu poets who continue to write in Urdu, including Gopi Chand Narang and Gulzar ). Urdu had been used as a literary medium for British colonial Indian writers from

SECTION 10

1500-477: A significant role in the development of the Urdu register. Hindi became the distinct register spoken by those who sought to construct a Hindu identity in the face of colonial rule. As Hindi separated from Hindustani to create a distinct spiritual identity, Urdu was employed to create a definitive Islamic identity for the Muslim population in India. Urdu's use was not confined only to northern India – it had been used as

1625-411: A stable and beneficial ecological balance. The presence of untreated wastewater and toxic waste has placed immense pressure on the mangrove forests within the vicinity of Chinna Creek. These vital ecosystems are under severe stress due to elevated toxicity levels, resulting in detrimental effects on their health and viability. Studies have highlighted the grave pollution levels within the creek, revealing

1750-594: A symbol of their religious identity. Hindus in northwestern India, under the Arya Samaj agitated against the sole use of the Perso-Arabic script and argued that the language should be written in the native Devanagari script, which triggered a backlash against the use of Hindi written in Devanagari by the Anjuman-e-Islamia of Lahore. Hindi in the Devanagari script and Urdu written in the Perso-Arabic script established

1875-449: A transition from the ocean to the land, where fresh and saltwater mix. The soil in these marshes is often made up of mud and a layer of organic material called peat. Peat is characterized as waterlogged and root-filled decomposing plant matter that often causes low oxygen levels (hypoxia). These hypoxic conditions causes growth of the bacteria that also gives salt marshes the sulfurous smell they are often known for. Salt marshes exist around

2000-419: A unique habitat for marine organisms and are a source for understanding many ecological processes. Over the last century, they have been the focus of extensive research, particularly in trophic ecology, and continue to provoke important ideas that are relevant beyond this unique ecosystem. For example, kelp forests can influence coastal oceanographic patterns and provide many ecosystem services . However,

2125-419: A uniting language. Urdu was chosen as a symbol of unity for the new Dominion of Pakistan in 1947, because it had already served as a lingua franca among Muslims in north and northwest of British Indian Empire . Urdu is also seen as a repertory for the cultural and social heritage of Pakistan. While Urdu and Islam together played important roles in developing the national identity of Pakistan, disputes in

2250-460: A vehicle of poetry, (especially under the Bahmanids ), and is known as Dakhini , which contains loanwords from Telugu and Marathi . From the 13th century until the end of the 18th century; the language now known as Urdu was called Hindi , Hindavi , Hindustani , Dehlavi , Dihlawi , Lahori , and Lashkari . The Delhi Sultanate established Persian as its official language in India,

2375-459: A very significant number among the nearly 800 districts of India, there is a small Urdu-speaking minority at least. In Araria district , Bihar, there is a plurality of Urdu speakers and near-plurality in Hyderabad district, Telangana (43.35% Telugu speakers and 43.24% Urdu speakers). Some Indian Muslim schools ( Madrasa ) teach Urdu as a first language and have their own syllabi and exams. In fact,

2500-413: Is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide. Since most inputs come from land, either via the rivers , sewage or the atmosphere, it means that continental shelves are more vulnerable to pollution. Air pollution

2625-542: Is a protected language in the constitution. It is also spoken as a minority language in Afghanistan and Bangladesh , with no official status. Urdu and Hindi share a common Sanskrit - and Prakrit -derived vocabulary base, phonology , syntax , and grammar, making them mutually intelligible during colloquial communication . While formal Urdu draws literary, political, and technical vocabulary from Persian , formal Hindi draws these aspects from Sanskrit; consequently,

2750-741: Is also a contributing factor by carrying off iron, carbonic acid, nitrogen , silicon, sulfur, pesticides or dust particles into the ocean. The pollution often comes from nonpoint sources such as agricultural runoff , wind-blown debris , and dust. These nonpoint sources are largely due to runoff that enters the ocean through rivers, but wind-blown debris and dust can also play a role, as these pollutants can settle into waterways and oceans. Pathways of pollution include direct discharge, land runoff, ship pollution , bilge pollution , atmospheric pollution and, potentially, deep sea mining . By integrating socioeconomic metrics with ecosystem management solutions, scientific findings can be utilized to benefit both

2875-579: Is attenuated within this first meter. Organisms here must contend with wave action and unique chemical and physical properties. The surface is utilised by a wide range of species, from various fish and cetaceans , to species that ride on ocean debris (termed rafters ). Most prominently, the surface is home to a unique community of free-living organisms, termed neuston (from the Greek word, υεω, which means both to swim and to float. Floating organisms are also sometimes referred to as pleuston , though neuston

Urdu language Urdu ( / ˈ ʊər d uː / ; اُردُو , pronounced [ʊɾduː] , ALA-LC : Urdū ) is a Persianised register of the Hindustani language , an Indo-Aryan language spoken chiefly in South Asia . It

3125-407: Is located between the low marsh and the upland border and it usually only flooded when higher than usual tides are present. The upland border is the freshwater edge of the marsh and is usually located at elevations slightly higher than the high marsh. This region is usually only flooded under extreme weather conditions and experiences much less waterlogged conditions and salt stress than other areas of

3250-582: Is more commonly used). Despite the diversity and importance of the ocean's surface in connecting disparate habitats, and the risks it faces, not a lot is known about neustonic life. A stream of airborne microorganisms circles the planet above weather systems but below commercial air lanes. Some peripatetic microorganisms are swept up from terrestrial dust storms, but most originate from marine microorganisms in sea spray . In 2018, scientists reported that hundreds of millions of viruses and tens of millions of bacteria are deposited daily on every square meter around

3375-515: Is not officially recognised by the Government of Bangladesh . The Urdu spoken by Stranded Pakistanis in Bangladesh is different from this dialect. Many bilingual or multi-lingual Urdu speakers, being familiar with both Urdu and English, display code-switching (referred to as " Urdish ") in certain localities and between certain social groups. On 14 August 2015, the Government of Pakistan launched

3500-488: Is one variety, is spoken much more widely, forming the third most commonly spoken language in the world, after Mandarin and English . The syntax (grammar), morphology , and the core vocabulary of Urdu and Hindi are essentially identical – thus linguists usually count them as one single language, while some contend that they are considered as two different languages for socio-political reasons. Owing to interaction with other languages, Urdu has become localised wherever it

3625-572: Is read and written as in other parts of India. A number of daily newspapers and several monthly magazines in Urdu are published in these states. Dhakaiya Urdu is a dialect native to the city of Old Dhaka in Bangladesh , dating back to the Mughal era . However, its popularity, even among native speakers, has been gradually declining since the Bengali Language Movement in the 20th century. It

3750-543: Is said to have arisen as the "language of the camp", or " Zaban-i-Ordu " means " Language of High camps " or natively " Lashkari Zaban " means " Language of Army " even though term Urdu held different meanings at that time. It is recorded that Aurangzeb spoke in Hindvi, which was most likely Persianized, as there are substantial evidence that Hindvi was written in the Persian script in this period. During this time period Urdu

3875-731: Is shared, though formal Urdu makes more use of the Persian "-e-" izafat grammatical construct (as in Hammam-e-Qadimi , or Nishan-e-Haider ) than does Hindi. The following table shows the number of Urdu speakers in some countries. Marine ecosystem Marine ecosystems are characterized by the biological community of organisms that they are associated with and their physical environment . Classes of organisms found in marine ecosystems include brown algae , dinoflagellates , corals , cephalopods , echinoderms , and sharks . Marine ecosystems are important sources of ecosystem services and food and jobs for significant portions of

Urdu is also spoken by large numbers of immigrants and their children in the major urban centres of the United Kingdom , the United States, Canada, Germany, New Zealand, Norway, and Australia. Along with Arabic , Urdu is among the immigrant languages with the most speakers in Catalonia . Religious and social atmospheres in early nineteenth century India played

4125-485: Is spoken, including in Pakistan. Urdu in Pakistan has undergone changes and has incorporated and borrowed many words from regional languages, thus allowing speakers of the language in Pakistan to distinguish themselves more easily and giving the language a decidedly Pakistani flavor. Similarly, the Urdu spoken in India can also be distinguished into many dialects such as the Standard Urdu of Lucknow and Delhi , as well as

Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef . These reefs are composed of large coral colonies of a variety of species living together. The corals form multiple symbiotic relationships with the organisms around them. Mangroves are trees or shrubs that grow in low-oxygen soil near coastlines in tropical or subtropical latitudes. They are an extremely productive and complex ecosystem that connects

4500-471: Is used in education , literature , office and court business, although in practice, English is used instead of Urdu in the higher echelons of government. Article 251(1) of the Pakistani Constitution mandates that Urdu be implemented as the sole language of government, though English continues to be the most widely used language at the higher echelons of Pakistani government. Urdu is also one of

Due to the large variance of conditions possible in this region, it is inhabited by resilient wildlife that can withstand these changes such as barnacles, marine snails, mussels and hermit crabs. Tides flow over

4750-566: The Bombay , Bengal , Orissa , and Hyderabad State as well. Before independence, Muslim League leader Muhammad Ali Jinnah advocated the use of Urdu, which he used as a symbol of national cohesion in Pakistan. After the Bengali language movement and the separation of former East Pakistan , Urdu was recognised as the sole national language of Pakistan in 1973, although English and regional languages were also granted official recognition. Following

4875-645: The Central Hindi Directorate was established earlier in 1960, and the promotion of Hindi is better funded and more advanced, while the status of Urdu has been undermined by the promotion of Hindi. Private Indian organisations such as the Anjuman-e-Tariqqi Urdu, Deeni Talimi Council and Urdu Mushafiz Dasta promote the use and preservation of Urdu, with the Anjuman successfully launching a campaign that reintroduced Urdu as an official language of Bihar in

5000-683: The Dakhni ( Deccan ) of South India. Because of Urdu's similarity to Hindi , speakers of the two languages can easily understand one another if both sides refrain from using literary vocabulary. Although Urdu is widely spoken and understood throughout all of Pakistan, only 9% of Pakistan's population spoke Urdu according to the 2023 Pakistani census . Most of the nearly three million Afghan refugees of different ethnic origins (such as Pashtun , Tajik , Uzbek , Hazarvi , and Turkmen ) who stayed in Pakistan for over twenty-five years have also become fluent in Urdu. Muhajirs since 1947 have historically formed

5500-580: The Karachi Port Trust (KPT) is not directly responsible for managing marine pollution, it was tasked with establishing a treatment plant near Mai Kolachi Road along the Chinna Creek as part of a Wetland Park Project . This initiative aims to address the issue of approximately 500 million gallons of untreated sewage being dumped into the Arabian Sea daily, representing 99% of the total sewage. The plant

5625-426: The Karachi Port Trust , was once lush with mangroves and abundant wildlife. However, efforts in recent decades to build the KPT Officers Society on 130 acres have resulted in substantial habitat destruction. The creek's land was appropriated, and the mangroves were cleared. The mangrove ecosystem of Chinna Creek not only served as a protective barrier against coastal erosion and storm surges but also contributed to

Additionally, there is an indirect impact stemming from approximately 200 million gallons per day of wastewater discharged by the Lyari River . These combined discharges have implications for the marine ecosystem of Chinna Creek, leading to the degradation and loss of natural flora and fauna essential for maintaining

6000-477: The Punjabi elite of Pakistan, have adopted Urdu as a mother tongue and identify with both an Urdu speaker as well as Punjabi identity. Urdu was chosen as a symbol of unity for the new state of Pakistan in 1947, because it had already served as a lingua franca among Muslims in north and northwest British India . It is written, spoken and used in all provinces/territories of Pakistan , and together with English as

Species at the surface are not distributed uniformly; the ocean's surface harbours unique neustonic communities and ecoregions found at only certain latitudes and only in specific ocean basins. But the surface is also on

6250-438: The carbon dioxide causing global warming and heat captured by global warming are absorbed by the ocean, ocean chemistry is changing through processes like ocean acidification which in turn threatens marine ecosystems. Because of the opportunities in marine ecosystems for humans and the threats created by humans, the international community has prioritized "Life below water" as Sustainable Development Goal 14 . The goal

There have been attempts to purge Urdu of native Prakrit and Sanskrit words, and Hindi of Persian loanwords – new vocabulary draws primarily from Persian and Arabic for Urdu and from Sanskrit for Hindi. English has exerted

7125-647: The 32 largest cities in the world, 22 are located on estuaries as they provide many environmental and economic benefits such as crucial habitat for many species, and being economic hubs for many coastal communities. Estuaries also provide essential ecosystem services such as water filtration, habitat protection, erosion control, gas regulation nutrient cycling, and it even gives education, recreation and tourism opportunities to people. Lagoons are areas that are separated from larger water by natural barriers such as coral reefs or sandbars. There are two types of lagoons, coastal and oceanic/atoll lagoons. A coastal lagoon is, as

7250-581: The Capital was relocated to Delhi and named Shahjahanabad and the Bazar of the town was named Urdu e Muallah. In the Akbar era the word Rekhta was used to describe Urdu for the first time.

It belongs to the Western Hindi group of the Central Indo-Aryan languages. The contact of Hindu and Muslim cultures during the period of Islamic conquests in the Indian subcontinent (12th to 16th centuries) led to the development of Hindustani as a product of a composite Ganga-Jamuni tehzeeb . In cities such as Delhi,

Some who are from a non-Urdu background now can read and write only Urdu. With such a large number of people(s) speaking Urdu, the language has acquired a peculiar Pakistani flavor further distinguishing it from the Urdu spoken by native speakers, resulting in more diversity within

8000-407: The ancient language Old Hindi began to acquire many Persian loanwords and continued to be called "Hindi" and later, also "Hindustani". An early literary tradition of Hindavi was founded by Amir Khusrau in the late 13th century.

The mangrove ecosystem is also an important source of food for many species as well as excellent at sequestering carbon dioxide from the atmosphere with global mangrove carbon storage is estimated at 34 million metric tons per year. Seagrasses form dense underwater meadows which are among the most productive ecosystems in

8375-421: The coast of Northern California . The implementation of marine protected areas is one management strategy useful for addressing such issues, since it may limit the impacts of fishing and buffer the ecosystem from additive effects of other environmental stressors. Estuaries occur where there is a noticeable change in salinity between saltwater and freshwater sources. This is typically found where rivers meet

8500-583: The court language of various Indo-Islamic empires . Religious, social, and political factors arose during the European colonial period that advocated a distinction between Urdu and Hindi, leading to the Hindi–Urdu controversy . According to 2022 estimates by Ethnologue and The World Factbook , produced by the Central Intelligence Agency (CIA), Urdu is the 10th-most widely spoken language in

Atoll lagoons are often much deeper than coastal lagoons. Most lagoons are very shallow meaning that they are greatly affected by changed in precipitation, evaporation and wind. This means that salinity and temperature are widely varied in lagoons and that they can have water that ranges from fresh to hypersaline. Lagoons can be found in on coasts all over

8875-415: The early 21st century an increasing percentage of Indian Muslims began switching to Hindi due to socio-economic factors, such as Urdu being abandoned as the language of instruction in much of India, and having limited employment opportunities compared to Hindi, English and regional languages. The number of Urdu speakers in India fell 1.5% between 2001 and 2011 (then 5.08 million Urdu speakers), especially in

Marine pollution occurs when substances used or spread by humans, such as industrial , agricultural and residential waste , particles , noise , excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there. The majority of this waste (80%) comes from land-based activity, although marine transportation significantly contributes as well. It

9500-508: The front line of climate change and pollution. Life on the ocean's surface connects worlds. From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment. This sun-drenched habitat can be defined as roughly one metre in depth, as nearly half of UV-B

9625-401: The global population . Human uses of marine ecosystems and pollution in marine ecosystems are significantly threats to the stability of these ecosystems. Environmental problems concerning marine ecosystems include unsustainable exploitation of marine resources (for example overfishing of certain species), marine pollution , climate change , and building on coastal areas. Moreover, much of

9750-518: The grammar and core Indo-Aryan vocabulary of the local Indian dialect Khariboli, it adopted the Nastaleeq writing system – which was developed as a style of Persian calligraphy. Throughout the history of the language, Urdu has been referred to by several other names: Hindi, Hindavi, Rekhta, Urdu-e-Muallah, Dakhini , Moors and Dehlavi . In 1773, the Swiss French soldier Antoine Polier notes that

9875-473: The independence movement. But after the 1947 Partition , when it was chosen as the national language of Pakistan to unite all inhabitants with one linguistic identity, it faced serious competition primarily from Bengali (spoken by 56% of the total population, mostly in East Pakistan until that attained independence in 1971 as Bangladesh ), and after 1971 from English. Both pro-independence elites that formed

10000-570: The influence of humans has often contributed to kelp forest degradation . Of particular concern are the effects of overfishing nearshore ecosystems, which can release herbivores from their normal population regulation and result in the overgrazing of kelp and other algae. This can rapidly result in transitions to barren landscapes where relatively few species persist. Already due to the combined effects of overfishing and climate change , kelp forests have all but disappeared in many especially vulnerable places, such as Tasmania 's east coast and

10125-532: The introduction of invasive species , ocean pollution , ocean acidification and ocean warming . These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. The ocean can be described as the world's largest ecosystem and it is home for many species of marine life. Different activities carried out and caused by human beings such as global warming, ocean acidification, and pollution affect marine life and its habitats. For

10250-428: The land and sea. Mangroves consist of species that are not necessarily related to each other and are often grouped for the characteristics they share rather than genetic similarity. Because of their proximity to the coast, they have all developed adaptions such as salt excretion and root aeration to live in salty, oxygen-depleted water. Mangroves can often be recognized by their dense tangle of roots that act to protect

10375-541: The language as " Moors " or "Moorish jargon". John Gilchrist was the first in British India to begin a systematic study on Urdu and began to use the term "Hindustani" what the majority of Europeans called "Moors", authoring the book The Strangers's East Indian Guide to the Hindoostanee or Grand Popular Language of India (improperly Called Moors) . Urdu was then promoted in colonial India by British policies to counter

10500-458: The language in the Perso-Arabic script in courts and government offices, though Hindus continued to employ the Devanagari script in certain literary and religious contexts. Through the late 19th century, people did not view Urdu and Hindi as being two distinct languages, though in urban areas, the standardised Hindustani language was increasingly being referred to as Urdu and written in the Perso-Arabic script. Urdu and English replaced Persian as

10625-570: The language of Bollywood films tend to contain a large number of Persian and Arabic words and thus considered to be "Urdu" in a sense, especially in songs. India has more than 3,000 Urdu publications, including 405 daily Urdu newspapers. Newspapers such as Neshat News Urdu , Sahara Urdu , Daily Salar , Hindustan Express , Daily Pasban , Siasat Daily , The Munsif Daily and Inqilab are published and distributed in Bangalore, Malegaon, Mysore, Hyderabad, and Mumbai . Outside South Asia, it

10750-883: The language. In India, Urdu is spoken in places where there are large Muslim minorities or cities that were bases for Muslim empires in the past. These include parts of Uttar Pradesh , Madhya Pradesh , Bihar , Telangana , Andhra Pradesh , Maharashtra ( Marathwada and Konkanis), Karnataka and cities such as Hyderabad , Lucknow , Delhi , Malerkotla , Bareilly , Meerut , Saharanpur , Muzaffarnagar , Roorkee , Deoband , Moradabad , Azamgarh , Bijnor , Najibabad , Rampur , Aligarh , Allahabad , Gorakhpur , Agra , Firozabad , Kanpur , Badaun , Bhopal , Hyderabad , Aurangabad , Bangalore , Kolkata , Mysore , Patna , Darbhanga , Gaya , Madhubani , Samastipur , Siwan , Saharsa , Supaul , Muzaffarpur , Nalanda , Munger , Bhagalpur , Araria , Gulbarga , Parbhani , Nanded , Malegaon , Bidar , Ajmer , and Ahmedabad . In

10875-729: The leadership of the Muslim League in Pakistan and the Hindu-dominated Congress Party in India had been educated in English during the British colonial period, and continued to operate in English and send their children to English-medium schools as they continued dominate both countries' post-Partition politics. Although the Anglicized elite in Pakistan has made attempts at Urduisation of education with varying degrees of success, no successful attempts were ever made to Urduise politics,

11000-466: The legal system, the army, or the economy, all of which remained solidly Anglophone. Even the regime of general Zia-ul-Haq (1977–1988), who came from a middle-class Punjabi family and initially fervently supported a rapid and complete Urduisation of Pakistani society (earning him the honorary title of the 'Patron of Urdu' in 1981), failed to make significant achievements, and by 1987 had abandoned most of his efforts in favour of pro-English policies. Since

11125-404: The main languages of instruction, although the people from differing provinces may have different native languages. Urdu is taught as a compulsory subject up to higher secondary school in both English and Urdu medium school systems, which has produced millions of second-language Urdu speakers among people whose native language is one of the other languages of Pakistan – which in turn has led to

11250-451: The majority population in the city of Karachi , however. Many newspapers are published in Urdu in Pakistan, including the Daily Jang , Nawa-i-Waqt , and Millat . No region in Pakistan uses Urdu as its mother tongue, though it is spoken as the first language of Muslim migrants (known as Muhajirs ) in Pakistan who left India after independence in 1947. Other communities, most notably

11375-456: The marsh. Intertidal zones are the areas that are visible and exposed to air during low tide and covered up by saltwater during high tide. There are four physical divisions of the intertidal zone with each one having its distinct characteristics and wildlife. These divisions are the Spray zone, High intertidal zone, Middle Intertidal zone, and Low intertidal zone. The Spray zone is a damp area that

11500-407: The meadows uprooting the grass, and overfishing which unbalances the ecosystem. Seagrass meadows are currently being destroyed at a rate of about two football fields every hour . Kelp forests occur worldwide throughout temperate and polar coastal oceans. In 2007, kelp forests were also discovered in tropical waters near Ecuador . Physically formed by brown macroalgae , kelp forests provide

11625-399: The middle intertidal zone two times a day and this zone has a larger variety of wildlife. The low intertidal zone is submerged nearly all the time except during the lowest tides and life is more abundant here due to the protection that the water gives. Organisms that live freely at the surface, termed neuston , include keystone organisms like the golden seaweed Sargassum that makes up

11750-403: The most Urdu-speaking states of Uttar Pradesh (c. 8% to 5%) and Bihar (c. 11.5% to 8.5%), even though the number of Muslims in these two states grew in the same period. Although Urdu is still very prominent in early 21st-century Indian pop culture, ranging from Bollywood to social media, knowledge of the Urdu script and the publication of books in Urdu have steadily declined, while policies of

11875-564: The most alive language and moving ahead with times" in India. This phenomenon pertains to the decrease in relative and absolute numbers of native Urdu speakers as opposed to speakers of other languages; declining (advanced) knowledge of Urdu's Perso-Arabic script, Urdu vocabulary and grammar; the role of translation and transliteration of literature from and into Urdu; the shifting cultural image of Urdu and socio-economic status associated with Urdu speakers (which negatively impacts especially their employment opportunities in both countries),

12000-628: The natural world, marine ecosystems also provide social, economic, and biological ecosystem services to humans. Pelagic marine systems regulate the global climate, contribute to the water cycle , maintain biodiversity, provide food and energy resources, and create opportunities for recreation and tourism. Economically, marine systems support billions of dollars worth of capture fisheries, aquaculture, offshore oil and gas, and trade and shipping. Ecosystem services fall into multiple categories, including supporting services, provisioning services, regulating services, and cultural services. The productivity of

12125-523: The ocean or sea. The wildlife found within estuaries is unique as the water in these areas is brackish - a mix of freshwater flowing to the ocean and salty seawater. Other types of estuaries also exist and have similar characteristics as traditional brackish estuaries. The Great Lakes are a prime example. There, river water mixes with lake water and creates freshwater estuaries. Estuaries are extremely productive ecosystems that many humans and animal species rely on for various activities. This can be seen as, of

12250-606: The oceans for environmental conservation purposes and to enable collaborative ecosystem-based management in transnational areas, in a way consistent with the 1982 UN Convention on the Law of the Sea . This name refers to relatively large regions on the order of 200,000 km (77,000 sq mi) or greater, characterized by their distinct bathymetry , hydrography , productivity , and trophically dependent populations . Such LMEs encompass coastal areas from river basins and estuaries to

12375-461: The official languages in northern parts of India in 1837. In colonial Indian Islamic schools, Muslims were taught Persian and Arabic as the languages of Indo-Islamic civilisation ; the British, in order to promote literacy among Indian Muslims and attract them to attend government schools, started to teach Urdu written in the Perso-Arabic script in these governmental educational institutions and after this time, Urdu began to be seen by Indian Muslims as

12500-565: The officially recognised languages in India and also has the status of "additional official language" in the Indian states of Andhra Pradesh , Uttar Pradesh , Bihar , Jharkhand , West Bengal , Telangana and the national capital territory Delhi . Also as one of the five official languages of Jammu and Kashmir . India established the governmental Bureau for the Promotion of Urdu in 1969, although

12625-438: The ongoing Hindi–Urdu controversy and modern cultural association of each language with the two religions has led to fewer Hindus using Urdu. In the 20th century, Indian Muslims gradually began to collectively embrace Urdu (for example, 'post-independence Muslim politics of Bihar saw a mobilisation around the Urdu language as tool of empowerment for minorities especially coming from weaker socio-economic backgrounds' ), but in

12750-668: The overall environmental health. However, the transformation of the creek's dynamics due to human interventions, including the closure of the Clifton entrance, had significant implications for the ecology and biodiversity of the area, altering the natural habitat and ecosystem dynamics over time. Chinna Creek faces significant environmental challenges due to the influx of untreated wastewater and toxic waste from various sources within Karachi. The creek receives inflows of approximately 16 million gallons of untreated wastewater daily, originating from

12875-596: The past 50 years, more than 90 percent of global warming resulting from human activity has been absorbed into the ocean. This results in the rise of ocean temperatures and ocean acidification which is harmful to many fish species and causes damage to habitats such as coral . With coral producing materials such as carbonate rock and calcareous sediment, this creates a unique and valuable ecosystem not only providing food/homes for marine creatures but also having many benefits for humans too. Ocean acidification caused by rising levels of carbon dioxide leads to coral bleaching where

13000-474: The planet. The deep sea contains up to 95% of the space occupied by living organisms. Combined with the sea floor (or benthic zone), these two areas have yet to be fully explored and have their organisms documented. In 1984, National Oceanic and Atmospheric Administration (NOAA) of the United States developed the concept of large marine ecosystems (sometimes abbreviated to LMEs), to identify areas of

13125-511: The position and prestige of English only grew stronger in the meantime. There are over 100 million native speakers of Urdu in India and Pakistan together: there were 50.8 million Urdu speakers in India (4.34% of the total population) as per the 2011 census; and approximately 16 million in Pakistan in 2006. There are several hundred thousand in the United Kingdom, Saudi Arabia, United States, and Bangladesh . However, Hindustani, of which Urdu

13250-476: The previous emphasis on Persian. In colonial India, "ordinary Muslims and Hindus alike spoke the same language in the United Provinces in the nineteenth century, namely Hindustani, whether called by that name or whether called Hindi, Urdu, or one of the regional dialects such as Braj or Awadhi ." Elites from Muslim communities, as well as a minority of Hindu elites, such as Munshis of Hindu origin, wrote

13375-614: The rates of calcification is lowered affecting coral growth. Additionally, another issue caused by humans which impacts marine life is marine plastic pollution , which poses a threat to marine life. According to the IPCC (2019), since 1950 "many marine species across various groups have undergone shifts in geographical range and seasonal activities in response to ocean warming, sea ice change and biogeochemical changes, such as oxygen loss, to their habitats." Coastal marine ecosystems experience growing population pressures with nearly 40% of people in

13500-636: The same language, Hindustani (or Hindi-Urdu), share a core vocabulary and grammar . Apart from religious associations, the differences are largely restricted to the standard forms : Standard Urdu is conventionally written in the Nastaliq style of the Persian alphabet and relies heavily on Persian and Arabic as a source for technical and literary vocabulary, whereas Standard Hindi is conventionally written in Devanāgarī and draws on Sanskrit . However, both share

13625-895: The seaward boundaries of continental shelves and the outer margins of the major ocean current systems. Altogether, there are 66 LMEs, which contribute an estimated $ 3 trillion annually. This includes being responsible for 90% of global annual marine fishery biomass . LME-based conservation is based on recognition that the world's coastal ocean waters are degraded by unsustainable fishing practices, habitat degradation , eutrophication , toxic pollution, aerosol contamination, and emerging diseases, and that positive actions to mitigate these threats require coordinated actions by governments and civil society to recover depleted fish populations, restore degraded habitats and reduce coastal pollution. Five modules are considered when assessing LMEs: productivity, fish and fisheries, pollution and ecosystem health , socioeconomics, and governance. Periodically assessing

13750-633: The state of each module within a marine LME is encouraged to ensure maintained health of the ecosystem and future benefit to managing governments. The Global Environment Facility (GEF) aids in managing LMEs off the coasts of Africa and Asia by creating resource management agreements between environmental, fisheries, energy and tourism ministers of bordering countries. This means participating countries share knowledge and resources pertaining to local LMEs to promote longevity and recovery of fisheries and other industries dependent upon LMEs. Large marine ecosystems include: In addition to providing many benefits to

13875-583: The style of Urdu spoken on a day-to-day basis in Pakistan is akin to neutral Hindustani that serves as the lingua franca of the northern Indian subcontinent. Since at least 1977, some commentators such as journalist Khushwant Singh have characterised Urdu as a "dying language", though others, such as Indian poet and writer Gulzar (who is popular in both countries and both language communities, but writes only in Urdu (script) and has difficulties reading Devanagari, so he lets others 'transcribe' his work) have disagreed with this assessment and state that Urdu "is

14000-592: The two languages' mutual intelligibility effectively decreases as the factor of formality increases. Urdu originated in the area of the Ganges-Yamuna Doab , though significant development occurred in the Deccan Plateau . In 1837, Urdu became an official language of the British East India Company , replacing Persian across northern India during Company rule ; Persian had until this point served as

14125-425: The two official languages of Pakistan (along with English). It is spoken and understood throughout the country, whereas the state-by-state languages (languages spoken throughout various regions) are the provincial languages , although only 7.57% of Pakistanis speak Urdu as their first language. Its official status has meant that Urdu is understood and spoken widely throughout Pakistan as a second or third language. It

14250-853: The water column such as temperature and salinity. This data can be used in conjunction with satellite measurements of chlorophyll and sea surface temperatures to validate measurements and observe trends on greater spatial and temporal scales. Bottom-trawl surveys and pelagic-species acoustic surveys are used to assess changes in fish biodiversity and abundance in LMEs. Fish populations can be surveyed for stock identification, length, stomach content, age-growth relationships, fecundity, coastal pollution and associated pathological conditions, as well as multispecies trophic relationships. Fish trawls can also collect sediment and inform us about ocean-bottom conditions such as anoxia . Human activities affect marine life and marine habitats through overfishing , habitat loss ,

14375-543: The way their leaves absorb energy from waves as they hit the coast. They keep coastal waters healthy by absorbing bacteria and nutrients, and slow the speed of climate change by sequestering carbon dioxide into the sediment of the ocean floor. Seagrasses evolved from marine algae which colonized land and became land plants, and then returned to the ocean about 100 million years ago. However, today seagrass meadows are being damaged by human activities such as pollution from land runoff, fishing boats that drag dredges or trawls across

14500-455: The world , with 230 million total speakers, including those who speak it as a second language . The name Urdu was first used by the poet Ghulam Hamadani Mushafi around 1780 for Hindustani language even though he himself also used Hindavi term in his poetry to define the language. Ordu means army in the Turkic languages . In late 18th century, it was known as Zaban-e-Urdu-e-Mualla زبانِ اُرْدُوئے مُعَلّٰی means language of

14625-449: The world and are needed for healthy ecosystems and a healthy economy. They are extremely productive ecosystems and they provide essential services for more than 75 percent of fishery species and protect shorelines from erosion and flooding. Salt marshes can be generally divided into the high marsh, low marsh, and the upland border. The low marsh is closer to the ocean, with it being flooded at nearly every tide except low tide. The high marsh

14750-438: The world living within 100 km of the coast. Humans often aggregate near coastal habitats to take advantage of ecosystem services. For example, coastal capture fisheries from mangroves and coral reef habitats are estimated to be worth a minimum of $ 34 billion per year. Yet, many of these habitats are either marginally protected or not protected. Mangrove area has declined worldwide by more than one-third since 1950, and 60% of

14875-776: The world's coral reefs are now immediately or directly threatened. Human development, aquaculture, and industrialization often lead to the destruction, replacement, or degradation of coastal habitats. Moving offshore, pelagic marine systems are directly threatened by overfishing . Global fisheries landings peaked in the late 1980s, but are now declining, despite increasing fishing effort . Fish biomass and average trophic level of fisheries landing are decreasing, leading to declines in marine biodiversity. In particular, local extinctions have led to declines in large, long-lived, slow-growing species, and those that have narrow geographic ranges. Biodiversity declines can lead to associated declines in ecosystem services. A long-term study reports

15000-466: The world, on every continent except Antarctica and is an extremely diverse habitat being home to a wide array of species including birds, fish, crabs, plankton and more. Lagoons are also important to the economy as they provide a wide array of ecosystem services in addition to being the home of so many different species. Some of these services include fisheries, nutrient cycling, flood protection, water filtration, and even human tradition. Salt marshes are

15125-425: The world. They provide habitats and food for a diversity of marine life comparable to coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs . They function as nursery habitats for shrimps, scallops and many commercial fish species. Seagrass meadows provide coastal storm protection by

15250-403: Was characterised by a lush ecosystem dominated by dense mangrove growth, predominantly consisting of the species Avicennia marina . These mangroves played a crucial role in maintaining the ecological balance of the region, providing habitat and sustenance to diverse flora and fauna endemic to the coastal areas of Karachi. The eastern section of Chinna Creek, overseen since the 19th century by

15375-512: Was described as being "completely encircled by two branches of the North Western Railway ." Prior to the establishment of the Karachi port in 1873 , Chinna Creek boasted two entrances: one at the Manora channel and another at Clifton . The Clifton entrance was sealed off, redirecting its flow to utilise the western breakwater as an intertidal reservoir. The natural landscape of Chinna Creek

15500-591: Was intentioned as means of unification for Muslims in Northern India and later Pakistan, it adopted a modified Perso-Arabic script. Urdu continued its role in developing a Pakistani identity as the Islamic Republic of Pakistan was established with the intent to construct a homeland for the Muslims of Colonial India. Several languages and dialects spoken throughout the regions of Pakistan produced an imminent need for

15625-547: Was referred to as "Moors", which simply meant Muslim, by European writers. John Ovington wrote in 1689: The language of the Moors is different from that of the ancient original inhabitants of India but is obliged to these Gentiles for its characters. For though the Moors dialect is peculiar to themselves, yet it is destitute of Letters to express it; and therefore, in all their Writings in their Mother Tongue, they borrow their letters from
