Water Pollution
The sea is full of bacteria, plants and animals which eat waste. The sea cleans itself if we do not use it as a dump.
But if we dump too much waste in the sea, the bacteria, plants and animals cannot recycle it quickly, so the water becomes polluted.
Chemicals from farms and factories get into the rivers; and the rivers carry the waste to the sea. The chemicals get into the food chain and so fish and other sea animals can become dangerous to eat.
The worst kind of sea pollution is oil pollution. Oil is black and dirty and there are toxic chemicals in it. If oil gets in the sea water, it stays on top of it. Air cannot get to the plants and animals under the water and they die. Water birds become dirty with oil and are not able to fly. Very few of them survive. One of the worst oil pollutions in the world took place in 2011 in the Gulf of Mexico. When millions of tons of oil went into the sea. People had to work for months to stop the pollution and to clean up the place.
In the Gulf War3 in 1991 people themselves put oil on fire. A lot of oil went into the sea, got onto the ground. There were lakes of burning oil everywhere. The oil went down under the ground and polluted the water there. The pollution was terrible. Electric street lights burned all day in Kuwait because of the smoke4 from burning oil. Black and dirty rain fell on the Himalayan Mountains, thousands kilometres away.

Объяснение:
В море полно бактерий, растений и животных, которые едят отходы. Море очищается, если мы не используем его как свалку.
Но если мы сбрасываем слишком много отходов в море, бактерии, растения и животные не могут быстро их перерабатывать, поэтому вода становится загрязненной.
Химикаты из ферм и заводов попадают в реки; и реки переносят отходы в море. Химикаты попадают в пищевую цепь, поэтому рыбы и другие морские животные могут стать опасными для употребления в пищу.
Наихудшим видом загрязнения моря является загрязнение нефтью. Масло черное и грязное, и в нем есть токсичные химикаты. Если масло попадает в морскую воду, оно остается на поверхности. Воздух не может добраться до растений и животных под водой, и они умирают. Водоплавающие птицы пачкаются маслом и не могут летать. Очень немногие из них выживают. Одно из худших нефтяных загрязнений в мире состоялось в 2011 году в Мексиканском заливе. Когда в море вылилось миллионы тонн нефти. Люди вынуждены были работать месяцами, чтобы остановить загрязнение и очистить место.
В первой войне в Персидском заливе в 1991 году люди сами подожгли нефть. Много масла вылилось в моря, проникло в землю. Во всем мире были озера с горящей нефтью. Нефть ушла под землю и загрязнила там воду. Загрязнение было ужасным. Электрические уличные фонари горели весь день в Кувейте из-за дыма горящей нефти. Черный и грязный дождь шел в Гималайских горах, в тысячах километров от происходящего.
