Recently I thought, what kind of world will we and our children live in? I would like to believe that it will be better, because all technologies adapt to the needs of people.

But there is one problem that has not yet been resolved. This is an environmental problem. For thousands of years people have been drinking clean water and breathing clean air. But then a scientific and technological revolution began. The ecology began to deteriorate rapidly, and this process does not stop, but becomes more and more intensive. Already in big cities, people wear gauze bandages. What will happen next?
