2. A.We throw away so much glass, paper, metal and plastic. We mustn't do that. We can recycle or reuse these things. B. Our factories throw a lot of dirt into the air. We are pol­luting the atmosphere. C. Our drinking water is full of chemicals. The seas are dirty because we continue to put chemicals and litter into them. D. We spend too much energy and burn a lot of gas, coal (yroль) and oil (Heфть). This causes global warming. E. Paper comes from trees. If we use a lot of paper we kill a lot of trees. Three hundred thousand square kilometres of forests disappear every year. F.The gases from aerosol cans and refrigerators can destroy the ozone layer. We can find alternatives to such gases. G. Animals are in danger. We pollute the atmosphere and dis­turb the wildlife. A lot of animals are disappearing
