Many students are optimistic about life in the

next fifty years. They think the world will be a

better place and that our lives will be greatly

improved. What's more, people will have a

higher standard of living and live longer.

However, other students are worried about the

future. They say that the world will become more

crowded. Therefore, there will be even more

environmental problems and we'll live in a world

with less energy available.

But in my opinion, I think we will find ways

to solve these problems and that everyone will

live more happily.
