Global problems of humanity

Global problems concern all humanity and need the cooperation of all states to solve. They sharpened through the industrial and scientific-technical revolutions, rapid population growth, the disturbed balance of nature and the world economy becoming one system. The main problems are: preserving peace and security (disarmament, non-proliferation of nuclear weapons), the ecological problem (climate change, pollution, loss of biodiversity, shortage of clean water), poverty and gaps in development, the demographic problem, food, energy and raw-material problems, use of the World Ocean, health and others. They are interlinked: for example population growth increases food demand and the way energy is produced affects the climate. The solution to the energy problem is saving energy and a gradual shift to alternative sources such as solar, wind and geothermal; for ecological problems international documents such as the 2015 Paris Agreement matter. Problems are solved not by a single state but through international cooperation and by the actions of each person.
