Ecology in antiquity Modern man has existed on Earth for about 40 thousand years. He began to engage in cattle breeding and agriculture only 10 thousand years ago. Therefore, for 30,000 years, hunting was an almost exclusive source of food and clothing. The improvement of tools and methods of hunting was accompanied by the death of a number of animal species.

However, the number of animals is decreasing not only as a result of direct extermination, but also due to the deterioration of the ecological conditions of their habitat. Deforestation, plowing steppes and prairies, draining swamps, polluting the waters of rivers, lakes and seas - all this, taken together, interferes with the normal life of wild animals, leads to a decrease in their numbers even when hunting is prohibited.

Tiger According to the latest data, there are only individuals of the Asian tiger left in the world - the main symbol of 2010. On the islands of Java and Bali, tigers have disappeared completely due to deforestation and poaching.

Leatherback Turtle The leatherback turtle, which has lived on our planet for hundreds of millions of years, has been brought to the brink of extinction by man in just a few centuries. For example, there are only adults left in the Pacific Ocean.

Mountain gorilla The last remaining 600 individuals may disappear along with their natural habitat as a result of deforestation. Many animals die from poachers' bullets and from human diseases such as measles. In addition, many circuses try to get at least one gorilla at their disposal.

Giant panda Even this one with the symbol of the World Wildlife Fund is on the verge of extinction: in wild nature there are only individuals.

Animal and vegetable world our planet is very large. But as a result of human activity, the process of extinction of unique representatives of the fauna is developing too rapidly. The number of many species has decreased significantly, and some of them have completely disappeared.

An environmental crisis can be:

global (a tense state of relations between humanity and nature, characterized by a discrepancy between development productive forces and production relations in human society to the resource-ecological possibilities of the biosphere);
local;

Renewable natural resources(soil, fresh groundwater, zones of active water exchange, flora and fauna);
Non-renewable (coal, oil, - i.e. resources that are not revived or are restored hundreds of times slower than they are spent);

Climate resources(atmospheric air, wind energy);
space resources(solar radiation and tidal energy);
Water resources(waters of the oceans);

Socio-political aspect (the results of human impact on nature depend not only on the development technical progress and population growth, but also on the social conditions in which they manifest themselves. Developing countries serve as an important source of raw materials for developed countries seeking to locate their extractive industries, use

their mineral and

protection of animals living in it); "width="640"

When using natural resources, it is necessary to be guided by the rule of regionality (must be taken into account when using subsoil, water resources, forests and wildlife);
the protection of one natural object can simultaneously mean the protection of other objects closely related to it (for example, the protection of a reservoir from pollution = the protection of animals living in it);

Throughout its history, mankind has repeatedly faced catastrophes - unexpected, disastrous events that brought death to people, destroyed their cities and crops. They were caused by various natural phenomena - volcanic eruption, earthquakes, tsunamis, floods, tornadoes, epidemics. Until recently, it seemed that the main culprit of unexpected disasters is unreasonable elements.

In early 1976, the Olympic Brewery supertanker with a displacement of 275,000 tons, the property of a company founded by the Greek magnate Onassis, crashed off the coast of Brittany. Up to 5 tons of fuel oil were poured out of the holes into the open sea daily. A monstrous black oil mess flooded the shores of the once picturesque French island of Ouessant. The government was forced to take naval forces and sapper units to clean the coast of the island.

April 26, 1986 - the worst accident in the history of mankind occurred at the Chernobyl nuclear power plant (Ukraine, USSR). As a result of the explosion of the fourth reactor, several million cubic meters of radioactive gases were released into the atmosphere, which many times exceeded the release from nuclear explosions over Hiroshima and Nagasaki. The winds carried radioactive substances throughout Europe. From a zone with a radius of 30 km from the exploded reactor, a complete evacuation of residents was carried out. Living in it is prohibited. Many years will pass before the whole horror of the Chernobyl catastrophe, its terrible consequences for mankind, will be known and comprehended.

The conclusion suggests itself: main reason environmental disasters of the second half of the XX century is the intervention of Man! Earthquakes and floods, droughts and explosions of underground gases - to all these disastrous events, a person applied his hand in one way or another.

Causes of environmental disasters in the second half of the 20th century: neglect of security measures, negligence of enterprise personnel, political and administrative ambitions, greed, thoughtless desire to save money and disinformation or complete concealment of information about the disaster.
