The planet Earth is mostly water. Oceans cover the biggest part of it – and there are lakes, rivers, streams, and even underground water.
People all over the world are worried about what is happening to the environment. Our oceans, seas, rivers and lakes are in danger. Factories produce a lot of wastes and pour them into the rivers. So they poison water. Rivers and lakes are polluted by garbage or by poisonous chemicals which are dumped right into them. This poison kills fish and sea animals. There is not enough oxygen in the water. Fish and reptiles can't live in this water.

THE MOST POLLUTED SEAS AND RIVERS OF THE WORLD
The river (Citarum) flows in the Western Java in Indonesia. This river is considered to be the most polluted river in the world. The river actively began to be polluted in the 80th years of the XX century, when the sharp lifting of the industry in Indonesia began. Besides industrial wastes into the river, the household garbage from Jakarta goes, where 9 million people live.
Yangzi's river, China The Yangzi is the longest in Asia and the third after Amazon and Nile river, has length of 6300 km. The Yangzi wins first place in WWF rating – 10 the dirtiest rivers in the world ,because more than 17 000 Chinese cities have no cleaning constructions and all waste migrates lengthways on a current. For such cities as Shanghai, Wuhan and Nanjing, this river is the only source of water therefore its condition belongs to the biggest problems of China. Yangzi's river
The Huang He (Yellow River) is the second-large river in China – its length makes 5464 km in length, and yellow color of water of the river received from loessial deposits. But now color became brown, and sometimes even happens also red – all because of the chemicals following from nearby plants. Due to the frequent change of a current and installation of the next dams, not many pieces the river dries up, and quickly developing cities increase level of pollution of waters. It, in turn, is a huge problem because it is the only source of water for million Chinese.

Waters of the Mediterranean Sea are especially polluted near large ports of the developed countries, such, as France, Italy, Spain. Every year in the sea casually or deliberately about 400 thousand tons of dangerous oil products and industrial drains merge. And on each square km of a seabed there are about 2000 subjects which are waste of activity of the person.
The Baltic Sea in itself is very dirty,, the sea is surrounded from all directions by industrialized countries: Sweden, Norway, Baltic countries. The Baltic fish isn't so safe, in its content mercury is exceeded. The Baltic Sea is also polluted by industrial drains.
The Black Sea is also present at this list of ecologically unsuccessful reservoirs. The rivers from all Europe flow into it, bringing different wastes of the person's activity. The Black Sea is polluted by oil products, Kerch accident in 2007 especially affected. The hydrogen sulfide, lying layers at the bottom of the Black Sea and periodically rising to a surface because of high summer temperatures worsens a situation.
