Environment is an essential part of our life. It is the source which we used to live and to do any actions. The environment is our surroundings. The quality of our life depends on the quality and proper existence of our environment. In these days we are harming and degrading the environment and indirectly harming ourselves-physically and biologically. So the ecosystem is affected. Its balance is affected and recycling phenomenon of ecosystem are tampered. Power of the technology and science has enabled the man to exploit the use of environment for selfish and indiscriminate use and create a problem for everyone. We have to adapt to the environment. We have to follow regenerative and recycling mechanism's. The young must be educated to live in harmony with environment rather than exploit it
In the past, the major need of people in this world was arable land. Man did not have to think about animate things. However, now the adverse effects on forests through over-population and the development of various chemical elements in the atmosphere have led to irregular rainfall and global warming. This global warming has brought changes in climate, including making perennial snow mountains melt, thereby adversely affecting not only human beings but also other living species.

This dangerous situation is being taken very seriously by the world. In the past the perennial snow mountains of Tibet had very thick snow. Older people say that these mountains were covered with thick snow when they were young and that the snows are getting sparser which may be an indication of the end of the world. It is a fact that climate change is a slow process taking thousands of years to realize its effect. Living beings and plant life on this planet also undergo change accordingly. Man's physical structure too changes from generation to generation along with the change in climatic conditions.
