Global problems of humanity - problems that have arisen as a result of the interaction of humanity and nature. While the standard of living and economic development increases significantly, the level of equilibrium or restoration of natural processes decreases. In the 21st century, the greatest threats to humanity are both social and environmental problems. Let's highlight three of them:

demographic problem;

environmental problem;

the problem of the nuclear threat.

Within each one, we can identify a number of other problems, but let us focus on the main ones, because it is their solution that will allow a person to preserve and restore the world in which he lives.

The 19th century, with the growth of production, the development of medicine and new social laws, led to an increase in the birth rate in underdeveloped countries. This situation persisted throughout the 20th century, and only in the 21st century did countries move from a demographic explosion to a demographic transition. This social policy is aimed at reducing the birth rate (legally in underdeveloped countries) and increasing mortality (by increasing the birth rate in countries where the aging of nations is planned). Controlling population growth will help to stabilize the social development of countries, which will lead to a reduction in national conflicts, a revision of foreign policy and an emphasis on solving domestic problems.

It is social instability, as well as the struggle for resources, that is the main cause of military conflicts between countries. With the invention of nuclear weapons, this problem has become global, because every knowledgeable person knows the consequences of a nuclear explosion. After its application in 1945, the politicians of the world thought about deterrence. In 1972, the world powers signed the first treaty on curbing the growth of weapons. Then the States adopted treaties on the reduction of nuclear weapons stockpiles. In 2017, the Treaty on the Prohibition of Nuclear Weapons was drawn up, it will enter into force after ratification by fifty States.

The 21st century has turned man to face an environmental catastrophe. There is also the pollution of the environment by industrial and household waste, the depletion of natural resources, the destruction of ecosystems as a result of illiterate use. With the growth and development of industry, people have reached a new level of consumption. Energy resources: oil, gas, coal-have been used on a scale that leads to the depletion of non-renewable natural deposits. At the same time, transport and industrial enterprises emit such a large amount of waste into the environment that disturbs the balance in nature due to the deterioration of water, air and soil pollution. This leads to the death of animals, the disappearance of rare species, mutation and the emergence of new diseases.

Today, solutions are a priority:

Control of the production of harmful substances (Montreal Protocol on Substances that Deplete the Ozone Layer, Kyoto Protocol);

equipping the production with modern high-tech waste disposal equipment;

sorting and recycling of garbage:

control over the consumption of energy resources (heat and electricity saving, maintenance of equipment in proper mode, to avoid losses and unauthorized emissions);

transition to alternative energy sources (solar, wind, tidal power plants, replacement of fuel engines with electric ones);

various conservation and recreational measures in wildlife.

Remaining indifferent to environmental problems, humanity is digging its own grave with its own hands. After all, decisions start with each of us. Consumption meters, a serviceable car, sorted and properly disposed of garbage-these are the first steps to solving environmental problems. This is the least that an ordinary citizen can do. Getting an education in the field of high technologies, medicine, economics and law will allow everyone to make a feasible contribution to the stabilization of relations between Humanity and the Earth.
