environmental crisis of global scale - Myth or Reality?Environmental problems arise from time to time, for many centuries in a row, each time becoming more and more threatening.But in the second half of the nineteenth century, thanks to the total industrialization of society, they sharpened repeatedly.Over the last hundred years, about two-thirds of all the forests growing on the planet, were cut down, about a quarter of fertile land became unusable.And today, thanks to the activities of huge mismanagement of agricultural holdings, growing for several years in a row in one place are depleting the land of culture, like corn, and etched, indiscriminately, fields of peasants and the surrounding forests, this process is much uskorils ,.
Every ten years, the world is losing seven percent of the fertile soil.From the fields of our planet each year shall be made up of twenty-six billion tons of fertile soil.There are signs that the global environmental crisis occurs.This character, this problem has become a matter of fact since the late fifties and early sixties of the past twentieth century.
modern ecological crisis is growing rapidly in every country, on every continent.The scale of human impact on nature is so great that there is a real threat of large biogeocenosis imbalance that can lead in the future to serious problems for the species diversity of nature and to the existence of mankind in a way to which we are accustomed to lately.In fact, the environmental crisis is the transition of all mankind to the next level of its dependence on gradually but steadily the impoverished surroundings.
How will presumably events unfold in the near future?
traditional areas in which developing environmental crisis:
- excretion increasing the area of land from agricultural land due to considerable abuse of chemical fertilizers, water and wind erosion and soil salinity.
- Increasing chemical impact on water, animal and vegetable products, the very environment in which man lives, the destruction of forests and the like - all of this can not but affect the health, and human life itself, not to mention the direct threat of the loss of capacityto self-reproduction of the natural environment.
- Increased emissions of various pollutants into the atmosphere - hundreds of thousands of tons of sulfur dioxide, hydrocarbons, carbon monoxide, and the like.These substances are gradually destroying the protective ozone layer around the planet, and the prospects for the elimination of this layer are unpredictable.
- Large areas of land are converted into landfills and industrial waste, which means that not only reduced the amount of land suitable for agriculture, but also formed pockets of high-risk chemical contamination and soil, and the atmosphere and groundwater.
- construct new nuclear power plants.And though their creators assure the security of people in their creations, but the scenario at this site we have already seen in the case of the Chernobyl disaster.Many people died, two of the city is completely deserted, forests, water, land contaminated by radioactive isotopes, radiation rain fell on the villages and towns, located thousands of kilometers from the accident site.
aggravate the environmental crisis, and local military conflicts.Laos, Afghanistan, Cambodia, Vietnam, Central America, Africa - as a result of these wars burned forest giant space that stood untouched for centuries, thousands of warships, training and fighting, dropped into the ocean a wide variety of ammunition and a huge amount of leaked oil.Humanity urgently need to revise their attitude to nature, otherwise it will answer destructional and sweep away from the face of the Earth most people.
