Water plants Lagarosiphon Ludwigia On our planet there is a lot of water; water is in rivers, in lakes, in ponds, in seas and in oceans. The water in the sea is salty, but in the river the water is fresh. In the water live many plants.

Water animals Tiger shark Slope In the water live fish and animals. A fish moves its tail from side and swims in the water. Fish are covered with scale. Some fish eat plants or smaller fish and worms under the water; others eat flies and other insects on the top of the water.

Sea turtles in danger Sea turtles are of different colours, shapes and sizes, they are found in the Mediterranean. They have existed for millions of years but their survival is now being threatened.

Importance of water Water is necessary for life. All organisms contain it, some drink it and some live in it. Plants and animals require water that is pure, and they cannot survive, if water contains toxic chemicals or harmful microorganisms. Water pollution kills large quantity of fish, birds, and other animals.

Water and its protection We must keep water clean in the rivers and lakes, because we need clean water for drinking. Plants and animals die in the water which is polluted. Especially great harm to the river and lakes is done by oil products.

The main problem of water pollution The problems associated with water pollution have the capabilities to disrupt life on our planet to a great extent. But global environment collapse is not inevitable.

Pollution Pollution, pollution – you can use the latest toothpaste And then rinse your month with industrial waste. Just go out for a breath of air And you’ll be ready for a Medicare. The city streets are quite a thrill – if the hoods don’t get the monoxide will. Pollution, pollution – wear a gas mask or a veil, Then yon can breathe – long as you don’t inhale. Fish gotta swim, birds gotta fly – But they don’t last long if they try. A generation which doesn’t think of nature will not have future!

Thank you for attention!
