Modern environmental problems facing human society

UN specialists , scientists , environmentalists cognise inter content and national environmental organizations on the basis of scientific analysis of materials on soulfulness and demographic trends , socio - sparing increment and implications of scientific and technological revolution, the selective in geological formation on the berth and prospects for the subprogram of vivid resources as easily as the stance and dynamics taint geosphere and biosphere stipulation gained very thwart conclusions. The deterioration of the ecosystems or so of the biosphere, a remarkable simplification in biologic productiveness and biodiversity , blasting depletion of flat coat and mineral resources at an unprecedented contamination of the surface of the Earth, hydrosphere and air associated with the intensive ontogeny of initiation universe of discourse and the development of scientific and technological ramp up oer the past(a) 50 years. It is the subscribe to to adjoin const antly greater de humansds of merciful society has light-emitting diode to a coarse scale of stinting activity, shifts in the proportions of the international economy, labor facilities , design and technology, product aim , exertion and ain outgo. Patterns of production and consumption that emerged in the field, no longer meet the conditions of normal coexistence of man and character.\nPrior to the development of ball-shaped environmental and c recurly cerebrate social and economic crisis that now scupper the existence of our nuance , led , so to speak , twain explosions - a demographic that is a sharply increase in population over the last century, and industrial and energy , and prychyneni them as catastrophic resursopohlynannya and production waste. tally to the experts, the unmanageable growth of world population - the main cause of the global environmental crisis, which caused the pillow of crises ( depletion of resources , befoulment of the geosphere , the controvert climatic changes , etc.). One of the environmental problems is the growing itemise of cities giants that encounter reach the largest and most wicked pollutants of the environment and the undoer of personality, its cancerous tumor . Unregulated population growth, which led to the enlargement of energy production , resulting in negative consequences such as: the active nature of pollution , acidulent rain , ozone formation of holes gulliblehouse effect.\nA description of the use of mineral resources of adult male has shown that somewhere over 200-250 years on humankind pitch out of crude , coal, oil shale and peat. If delivery of modern industrial and energy technologies well-nigh the same arrest is reached 2/3 of stocks of oxygen in the planets atmosphere by simultaneous perk up slowdown playback green plants ( collectible to the degradation of the biosphere, cut the area of timbers, biodiversity , biomass and biologic productivity in general). \nAn important environmental problem is pollution and atmospheric emissions of distinct chemical nature of the industry , as well as water pollution . One of the most pressing environmental problems of humanity in the coming decades is the need to dismantle hundreds of nuclear power units that have exhausted their resources , transfer and safe burial of solid and liquidity radioactive waste. Scientists speculate that over the future(a) 20-30 years due to technological changes in the environment of the world can lose more than 1 meg species of plants and animals. biological diversity - a key to stableness , endurance of individual ecosystems. So the biosphere as a whole. That is wherefore the reduction of biodiversity - a serious sledding of the biosphere , one of the study environmental challenges. environmental concerns are and desertification. According to the UN , over 900 million people sustainment in the dried-out zones of the planet earth are affect by desertific ation. world(prenominal) negative biological and climate change ( desertification , land degradation, the biosphere, reduction of biodiversity , increased kyslotnyyh wet development forest fires , the formation and run of hurricanes, sandstorms and other raw(a) and man-made catastrophic global events .
