Question 4```Our planet is at risk. Our environment is under threat. The air we breathe the water we drink, the seas we fish in and soils we farm, the forests animals and plants which surround us are in danger. New terms and words describe these problems: acid rain, the greenhouse effect global warming holes in the ozone layer, desertification and industrial pollution. We are changing our environment. More and more gases and wastes escape from our factories. Rubbish, oil spillage, sand detergents damage our rivers and seas- forest give us timber and paper, but their loss results in soil erosion and also endanger wildlife. The richer countries of the world are mainly responsible for industrial pollution. This is where most of all the commercial energy is produced. In developing countries, poverty causes people to change their environment to over-graze grassland, to cut down trees for new land and firewood, to farm poor soil for food.

The United Nations Environmental Protection Agency says that an area of forest the size of Sierra Leone disappeared every year. Trees are cut down for timber which is used for building, furniture paper and fuel. They are also destroyed to provide land on which to graze animals and build new villages and towns. But downpour of rain and their root help to hold the soil together. Forests are also the home of many living things. The Amazon forest contain one fifth of all the species of birds in the world. In our forests, there may be plants and animals which could help in the discovery of new medicines of crops. To rescue and conserve our beautiful world, we must act cooperatively. Individuals, communities, nations and international associations, all have a responsibility. By learning to protect the natural environment, we can manage the earth's resources for generations to come```
