Humanity will come early, and probably late, to the recognition of the need for international agreements to limit pollution and impacts on the biosphere according to the limits agreed for each country. Only such a radical way can prevent the development of a global ecological crisis on Earth. We have proposed a method for calculating the permissible pollution of the biosphere as a whole. According to our calculations, the annual mineralization and destruction of organic matter on Earth is accompanied by the formation of up to 9-12 billion tons of pollutants. In accordance with the ten percent rule, the permissible limit of all emissions on Earth is 0.9-1.2 billion tons. At present, emissions are 3-4 billion tons, and according to the latest data, 6 billion tons, i.e. 5 times higher than the permissible value. Countries' limits on technogenic pollution can be obtained by multiplying 0.9-1.2 billion tons on the relative contribution of their phytosphere to the annual bioproductivity of the Earth.
