On the worldwide root the merciful beings population has revealed a J shaped pattern (fig 1 and 2) of escalation over the past years, while the availability of natural funds are required for human survival is in late decline (Cohen J.E.1995).

physique 1 Human population growth work on 2000 (2) Population policies which ge ars to reduce future growth represent lawfu! l responses to the environmental implications of population size (Stern et all 1995) although fertility step-down cannot be seen as sufficient response to contemporary human bring on environmental change. A decrease in human numbers game does not necessarily extract a decrease in environmentally significant behaviours. In addition, supposition that each further individual has an equal carry on on resources is too simplistic. Factors related to both the individual and to the fond and environmental...
