Ⅶ.Life in the future: for better or worse?
Many students are optimistic about the next fifty years. In fact, they think that the world will be a better place than it is now and our lives will be greatly improved. As a result, people will have a higher standard of living and live longer.
However.other students are worried about the future. They say the world become more crowded.Therefore, we will have even more environmental problems live in a world with Iess energy available.
But in my opinion,l think we will find ways to solve our problems and everyone will live more happily.
