World circumstantial degradation
of natural resources, wild animal, and environmental pollution has been brought
every community, fund and organization and nation for conservation of
environment and natural resources for long time sustainable development in
common practice. Declining condition of natural environmental source, highly
pressure of population, atmosphere pollution, industrial production, and production
of greenhouse effect gases negatively effects on global climate change bribing
challenge for biosphere global ecological situation make the world’s developed
and developing countries in united for conservation of environment, sustainable
development of economics, human and security for entire living system by making
polices.
There has been seen many
international conferences held for improve and conservation of environmental situation.
Many policies and strategies have made these conferences and still applying it

practice for environmental conservation. This message helped to the American
government to build national policies in 1873 for conservation of forest and
started to control the hunting activities of wild animals and species.
The world’s common policies for
conserve environmental situation
1 Maintains the essential
ecological processes and life support systems on which we survive.
2 preserve the genetic diversity
on which ecological processes of life support system are based.
3 Ensure the sustainable utilization
of species and ecosystems which support millions of biological communities.
