Read the passage and choose the correct answer to each of the following questions.

The environment is everything around us, both natural and made by man. A major

problem in the world today is the destruction of the natural environment.

This is a complicated problem. We burn fuel, and this causes air pollution. We throw

away plastic bags, containing toys and other objects. These stay in the environment, they

are not like paper or wood that slowly disappear. We have made thousands of new

chemicals. Factories that make or use chemicals always have chemical wastes. These are

often poisonous, and they also stay in the environment.

Since 1945 several countries have been testing nuclear bombs in the air and

underground. The explosions in the air cause nuclear fallout. The fallout causes cancer

and kills animals and people. Nuclear power plants that make electricity also produce

dangerous wastes and have accidents that can be very disastrous.
