What is the most important problem of the changing world from your point of view?

There are several problems. The main one is long overdue. This is a problem with food and drinking water. At the moment, a huge number of people are not getting enough rations. This problem is especially common in African countries. The water problem complements it and makes it catastrophic. All this is complemented by the problem of war. Due to military conflicts, there is a massive migration of people to Europe. This is also a problem. Nobody is waiting for them there and there they are not needed at all. They oversaturate the labor market and significantly increase the population.
