Some young people may be pessimistic about the future of the world. I think the reason for this is that young people will deplete our water resources in the future, the soils will dry out, the possibility of food will be lost, the fact that animals will become extinct, and also the extinction of plant species and the decrease of species.
Optimistic-minded young people think that current people will use all resources properly. They think that they will protect nature, that people will not harm nature and living things, and that they will do what is necessary to prevent climate and global warming.
I think in the future technology will advance and life will become easier. With the advancement of technology, a solution will be found for diseases. Feelings of sadness and boredom will decrease, lessons will be more fun. There will be no automobile accidents, and very few if any. Houses can be designed according to our taste.
Whatever we think, we should think well, as it is highly likely to happen to us. We must always be positive. We must protect nature and treat everyone well.
