each year is extracted from the earth about one hundred billion tons of resources, including fuel, ninety billion of whom later turned into waste.Therefore, the issue of resource these days has become very topical.If at the beginning of the last century using only twenty chemical elements of the periodic table, in our time - more than ninety.Over the past four decades has increased the consumption of resources in the twenty-five times, and the amount of waste produced - a hundred times.
rational use of natural resources - is the most important problem of the modern society.Development of the progress in science and technology is accompanied by a negative impact on the environment.The natural conditions - it is something that a person can not affect, as an example you can bring climate.Natural resources - a natural phenomena or objects that are used to meet the material needs of society, or for production, contributing to creating and maintaining the conditions necessary for the existence of mankind, as well as to improve living standards.
rational use of natural resources is the result of a reasonable investigation, which prevents the harmful effects of human activity, increases productivity and supports the natural complexes and objects of nature.Natural resources can be divided into several basic types: virtually inexhaustible (air, solar, intraterrestrial heat and so on), renewable (plant, soil), non-renewable (living space, natural resources, energy, rivers and so on).
rational use of renewable natural resources should be based on the type of suspension of expenditure, as well as renewal, providing for their reproduction.Their stocks usually recover more quickly than used.Rational use of non-renewable natural resources should be based on the type of economical and integrated their production and expenditure, as well as recycling of various wastes.Natural resources can also be divided into potential and actual.Potential resources engage in economic turnover, and real - are actively using.Unfortunately, today there is a problem of depletion of natural resources.Their level has decreased to such an extent that it becomes low man.Due to the depletion of the natural resources of their further development is more economical and environmentally inappropriate.When uncontrolled use of certain kinds of resources may disappear, and the process of self-renewal stop.The term recovery of some of them is a few hundred or even thousands of years.
Any human intervention entails the destruction of the unity between man and nature.The continued existence of life on Earth will depend on the growth of production, which in turn depends on the depletion of natural resources.Therefore, natural resources and their rational use must be under the strict control of the whole of humanity as a whole.It is necessary to make rational use of natural resources, to prevent the possible harmful effects of human activity, to maintain and improve the productivity of individual objects of nature and natural systems in general.
Proper use of natural resources - is the choice of a more suitable option for achieving economic, social and environmental impact of use of natural resources.Especially important is the integrated use of them, which involves the use of low-waste and non-waste technologies, re-use of recycled resources.This saves resources and prevents environmental pollution food production.
