9. What can we do?
1) Using smokeless sources of energy like biogas, solar etc.
2) Using devices for filtering smoke in chimneys of factories.
3) Planting more trees (afforestation and reforestation)
4) Recycling-various products instead of dumping them into rivers, e.g.,
biogas can be made from city waste.
5) Avoiding polythene bags.
11. Conclusion
We know that certain environmental conditions like air, water,& food are
essential for man’s survival. Apart from their availability their quality &
quantity must be assured according to man's natural & acquired capacity
for sustenance progress in industrialization has brought environmental
hazards such as air water & noise pollution. These have caused many health
problems & diseases.
As it has been said-
we do not inherit the environment from our forefathers,we
borrow it from future generation.
Stockholm conference of 1972 proclaims that:
The protection & improvement of human environment is a major issue
which affects the well being of people & economic development throughout
the world & it is duty of all governments & people to common efforts for
the preservation & improvement of environment for the benefit of all
people & their prosperity.
12. This year’s theme for World Environment Day – Go
Wild for Life – encourages you to celebrate all those
species under threat and take action of your own to
help safeguard them for future generations. This
can be about animals or plants that are threatened
within your local area as well as at the national or
global level - many local extinctions will eventually
add up to a global extinction! Whoever you are, and
wherever you live, show zero-tolerance for the
illegal trade in wildlife in word and deed, and make
a difference.
