2. For example, waste gases cause acid rains; this leads to forest damage and therefore reduces the resources of forests. Another problem is water shortage resulting from unlimited use of it. The third one is destroying the ozone layer of the Earth through pollution from plants and cars. One more problem is damage to wildlife. It is possible that some kinds of animals can disappear due to people’s activities.

The Telephone

Alexander Graham Bell never planned to be an inventor, he wanted to be a musician or a teacher of deaf people. The subjects that he studied at school included music, art, literature, Latin and Greek. They didn’t include German, which all scientists used in their books.

When Alexander was only sixteen, he became a teacher in boys’ school in Scotland. He liked teaching there but still he wanted to become a teacher of deaf people. He read all the books about sound that he could find and started to work on some of his own experiments. At twenty-five Alexander became interested in finding a way of sending human voice through an electric wire. The parents of his pupils contributed money for the equipment. He found an assistant, Tom Watson, who worked in an electric shop. For two years Tom and Alexander had been working together to build a machine that people could use to talk one to another over long distances. One day they were working on a new transmitter. Tom Watson, who was alone in another room, heard a voice. The voice was coming through a wire to a receiver on the table. The voice was of Alexander Bell. It was saying. “Come here, Mr Watson. I need you.”
