INTRODUCTION:-
GREENHOUSE EFFECT:-
It is warming effect found in greenhouse by allowing solar radiation to pass in but preventing long wave wave heat radiation to pass out due to glass paints water vapours in carbon dioxide.
The gases which are transparent to solar radiation but retain and partially reflect back long wave heat radiation are called greenhouse gases.
Green house gases are response essential for keeping the earth warm and hospitable.
They are also call radiatavely active gases
Regular assessment of abundance of greenhouse gases and their impact on global environment is being made by IPCC.
The various greenhouse gases are carbon dioxide carbons and nitrous oxide
ENVIRONMENT POLLUTION :-
Human population size has grown enormously over the last 100 years. This means increase in demand for food water home electricity roads automobiles and numerous other commodities. This demand sar exerting tremendous pressure on our natural resources and are also contributing to pollution of air water and soil.
The need of the hour is to check the degradation and depletion of our precious natural resources and pollution without halting the process of development.
Pollution is any undesirable change in physical chemical characteristics of air land water or soil.
Agents that bring about such as an undesirable change are called pollutants.
In order to control in environmental pollution the Government of India has pass the environment protection act 1986 to protect any program quality of our environment air water and soil.
