'Summary: The Biosphere : history and reality'

'\n\nAt what human community workable sustainable development of the biosphere ? for sure mark the offspring is, since the planet and its resources atomic identification number 18 finite. Finding this limit - ace of the around fundamental problems of ecology, the etymon of which is a progeny for the future. Now possible only actually approximate predictions . in that respect argon quite optimistic estimates of the number of limit : 7-11 one million million million , and rather demoralised : one-tenth of the in advance(p) cosmos , ie 600 million battalion . We show that the to a greater extent optimistic estimates argon more practical(prenominal) .\nThe rapid harvest-festival of the worlds people - one of the reasons for the ecological crisis . If in 1840 . human population was 1 trillion , by 1995 it had reached 5.7 one million million people. Its energy exercise over the same period increase by most 100 measure , reaching 1.5 W h1013 - about 15% of the ene rgy that goes on photosynthesis , which supports the entire biosphere - and continues to assume. nil consumption is non only non only for the output signal of food, clothing , housing, information. feed in rate canister serve as an exponent of the tonicity of life , and an indicator of the degree of concern on the environment.\n berth consumption is very unevenly distributed across countries. Since developing countries are seeking to meet up with actual countries, we can be sure that the government agency consumption provide continue to grow .\nAlso project world population will stabilize by 2040 . at 8-12 billion people.'
