The author draws attention to the development of crisis phenomena in most of the developed countries of the world. Possible scenarios for resolving the growing crisis contradictions are briefly analyzed. It is noted that quite serious armed conflicts are not excluded, in which a drop in the standard of living of the population of many countries of the world is inevitable. It is noted that in this scenario, the developed agriculture will contribute to the minimum inevitable losses among the population of those countries that will be involved in the conflict. In a scenario in which armed clashes will not be a serious enough problem for developed countries, there will be a problem of a decrease in the number of the indigenous population of these countries, their replacement by a population with other cultural traditions, or, in general, a critical decrease in population density. The author analyzes the reasons for this phenomenon and comes to the conclusion that it is possible to reverse the current trend by involving the population in the development of agriculture on modern principles.
