Man and nature are inseparable and closely interrelated. Forhumans, as well as for society as a whole, nature is the environment
of life and the only source of resources necessary for existence.
Nature and natural resources are the basis on which human society
lives and develops, the primary source of meeting the material and
spiritual needs of people. Without the natural environment, society
cannot exist. Man is a part of nature and, as a living being, exerts a
tangible influence on the natural environment by his elementary vital
activity.

Environmentalcrisis
Ecological crisis – the crisis of the relationship
between society and nature, the preservation of the
environment. For thousands of years, man has
constantly increased his technical capabilities,
increased his interference with nature, forgetting
about the need to maintain biological balance in it.

The environmental burden increased especiallysharply in the second half of the 20th century. There
was a qualitative leap in the relationship between
society and nature, when, as a result of a sharp
increase in the population, intensive industrialization
and urbanization of our planet, economic loads began
to exceed the ability of ecological systems to selfclean and regenerate everywhere. As a result, the
natural cycle of substances in the biosphere was
disrupted, and the health of the current and future
generations of people was threatened. The

DEPLETION ANDDESTRUCTION OF
THE NATURAL
ENVIRONMENT
At least 94% of the roughly half a billion different
species that lived on earth have disappeared or
evolved into new species. Mass extinction in the
distant past occurred as a result of unknown
natural causes. However, since agriculture began
10,000 years ago, the rate of species extinction has
increased millions of times as a result of human
activity, and this trend is expected to continue in
the coming decades.

Household and industrial waste is one of the factors of destruction of thenatural environment. Household and industrial waste is one of the factors of
destruction of the natural environment. For many years, recycling activities
were hampered by the perception that any business should be profitable. But
what was forgotten was that recycling, compared to landfill and incineration, is
the most effective way to solve the waste problem, since it requires less
government subsidies. In addition, it allows you to save energy and protect the
environment. And as the cost of landfill space increases due to stricter
regulations, and furnaces are too expensive and dangerous to the environment,
the role of waste recycling will steadily increase.

BASIC PRINCIPLESAND METHODS OF
ENVIRONMENTAL
PROTECTION
Three main strategies are used to protect
endangered and endangered wild species and to
prevent the danger to which other species may be
exposed: The adoption of agreements, laws and
the establishment of nature reserves The use of
gene banks, zoos, research centers, botanical
gardens and aquariums to preserve a small number
of wild animals The protection and protection of
the diversity of unique and typical ecosystems
around the world
