A. 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 lastic 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.

When he was 23, Bell emigrated to Canada with his parents and the next year moved to the United States to teach deaf-mute children. With his colleague Thomas Watson, Bell worked very hard on the experimentation to invent devices such as the harmonic telegraph(used to send multiple messages over a single wire) andphonautograph (used to draw the shape of the sound waves). The first telephone communication was said to have happened between Bell and Watson in 1876 while Bell was at one end of the line, and Watson worked on the telephone in other room. The first transmitted words were, ‘Mr Watson, come here. I want to see you’.
