The relationship of nature and society - the dialectical unity of man and the environment. Man as an integral part of the Earth’s biomass throughout the evolution was and is directly dependent on the surrounding nature. With the development of higher nervous activity, man himself becomes a powerful environmental factor (anthropogenic factor), therefore its influence on nature is dual-positive and negative.
Nature protection is a set of international, state and regional activities aimed at maintaining the nature of the Earth in a state corresponding to the evolutionary level of the modern biosphere and its living matter, including man.
Protection of the environment from pollution - a system of measures aimed at eliminating the negative impact of man, which is expressed in industrial emissions of poisonous gases, the discharge of polluted water, clogging of soil and water by pesticides, combustible materials, radioactive substances, in the creation of intense noise, etc.
