The environment is everything around us, both natural and man-made. A major problem in the world today is the destruction of the natural environment.
This is complicated problem. We burn fuels, and this causes air pollution. We throw away many kinds of plastic things such as plastic bags, toys and even tables and chairs. These stay in the environment, they are not like paper or wood that slowly disappear. We have also 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. Humans seem to be good at poisoning themselves.
