The environment is everything around us, both natural and made by man.
The biggest 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 some
countries have been testing nuclear bombs in the air and underground. These
explosions in the air cause nuclear fall-out. The fall-out 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.
