I’m going to speak about some kinds of pollution, for example air pollution or acid rain, water pollution. Now different kinds of trees, many of the animals, birds, fish are in serious danger. What should government do to stop the polluting, nowadays?
First of all I would like to speak about water pollution. There is no ocean or sea which is not used as a dump. Many rivers and lakes are poisoned, too. Fish and reptiles can’t live in them. There is not enough oxygen in the water. It happens so because factories and plants produce a lot of waste and pour it into rivers.
Now an even greater danger is threatening the woods and forests of Europe. This new danger attacks all trees – deciduous trees like oak, beech, birch as well as coniferous trees like fir and pine. First the branches turn yellow and brown. Then the tree’s needles or leaves fall. The roots and the trunk shrink. Finally the tree die. But what is killing the trees.
Nobody knows exactly but it is probably air pollution or acid rain. Factories, power stations, cars emit tons of smoke into the air. This smoke contains sulfur dioxide and nitrogen oxide. These substances mix with water vapour in the atmosphere and form sulfuric acid and nitric acid.…
