What global problems threaten humanity?

1. The most basic problem is that even now, a significant part of humanity is experiencing a lack of food and fresh water. The population is constantly growing and this problem will become more and more acute. This is a food problem.
2. The previous problem is closely intertwined with the first. Absolutely uncontrolled population growth in some states creates a shortage of food and water. Insufficient fertility in other countries leads to the disappearance of nationalities. There is uncontrolled migration from countries with high birth rates to others. These are demographic problems.
3. The more people on the planet, the more they generate various waste. This is an environmental problem.
4. The energy problem is partly caused by raw materials and overpopulation. Many people have many needs. This requires raw materials and energy.
5. The problem of peace and disarmament. Wars have been and will always be. But modern technology can destroy everyone.
6. The use of the resources of the World Ocean is directly related to overpopulation and the need for food, raw materials, energy.
7. Peaceful space exploration is currently unlikely. Even now, all powerful states have spy satellites.
