 The following are predictions about the second half of the twenty-first century:

          The world’s population will increase from the present 6 billion to 10 billion. Most of this increase will be in Africa, Asia, and Latin America.

          The earth’s climate will become warmer. This will create major problems for agriculture and we will see droughts and famine in Africa. We will even see these problems in southern Europe.

          Attempts to produce an electric vehicle will fail and we’ll continue to use our normal cars. In the second half of the 21^st century, however, the world’s supplies of petroleum will run out.

          With new technology people won’t need to be in the same place to communicate easily. They’ll be able to stay at home and do everything by computer and videophone.

          Patterns of work may change. People might decide  that they don’t actually need to go to banks, offices, schools, universities or shop any more.
