What ecological problems do you know? (Snowball method)
P1 I found a lot of information connected with the problem of the ozone layer. The pollution and the ozone layer destruction could lead our planet to a global catastrophy. About 5 billion tons of carbon dioxide is released in to the atmosphere every year. These gases hold heat. Trees and plants help to take gases such as carbon dioxide from the atmosphere, but we have now destroyed too many trees. There aren’t enough trees and plants to do this job. We make carbon dioxide when we burn wood of drive cars.
P2 People have to solve a lot of environmental problems and one of them is water pollution. For example, lake Baikal. Fifty percent of the world’s purest water has been ruined by the activity of a pulp – and – paper factory. It was the problem of Baikal that made out people think seriously about the man – nature relationship.
P3 More than 30 years ago the Aral was a bright blue sea with a lot of fish. The rivers Amudarya and Syrdarya supplied it with water. But then the water of the rivers was diverted to cotton plantations. As a result, the level of the sea has dropped 13 metres and the shores have gone back 70-80 kilometres. The exposed seabed has turned into a desert which sends 70 million tons of salty dust info the atmosphere every year. The disaster in the Aral puts in a dangerous position the health and lives of nearly three million people living by the sea.
