- Many environmental problems have been arisen due to effect of various natural and
artificial factors on the Earth.
- Environmental pollution is one of those main factors.
- Environmental pollution:
Unacceptable & unnecessary change in the surrounding environment due to natural
factors or human activities (i.e artificial factors) is called as environmental pollution.
OR
Direct or indirect changes in surrounding environment by physically, chemically, and
biologically which will be harmful to human and other living beings is environmental
pollution.
- Environmental pollution affect on existence of all the living organisms due to this, we
need of environmental conservation.
types of pollutions:
Air, water, sound, soil, thermal, Radioactive pollution etc.
