Read the passage below and answer the questions that follow.
Our planet is at risk. Our environment is under threat. The air we breathe, the water we drink, the seas we fish in, the soils we farm, the forest, animals and plants which surround us are in danger.
More and more gases and rubbish escape from our factories. Rubbish, oil spillage and detergents damage our rivers and seas. The loss of forests results in soil erosion and also endangers wildlife.
The richer countries of the world are mainly responsible for industrial pollution. This is where most of the commercial energy is consumed.
In developing countries, poverty causes people to overgraze grasslands and to cut down trees for timber building, furniture and fuel. They are also destroyed to provide land on which to graze animals and build new villages and towns.
But trees are needed to protect the land from heavy down pour of rain and their roots help hold the soil together. In our forests, there may be plants and animals which could help in the discovery of new medicines or 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.
