To save our mother nature we have to unite ourselves. Stop polluting the environment and grow more and more trees. yes! this is the only way in which we protect our earth. If you afford a little more then you can use CNG in our vehicles in place of petrols and deasels. Turn off the engine at traffic jam and signal. Encourage every one to participate in campaign like** Van Mohtsav** . You have to plant individually more trees in your house and in your locality.
