All of us must take a pledge to protect our environment. The joint effort of every one can easily protect the environment from contamination. We should not put garbage, flowers, worship material, burnt wood, idols etc. in the rivers, nor let anyone else put them in the rivers.
We have to bring awareness among people that these works pollute the environment. People should be stopped from washing clothes and bathing animals on river, ponds so that the environment is not polluted.
The remaining dirt of the big factories, leftover oil, garbage, etc. Should be stopped from flowing in rivers. If this is happening somewhere, we should try to stop it. If there is protection of human being only in the protection of nature.
