What can people here do to save Earth?

instead of blaming and thinking what to do. we have to walk the talk. as for me, we have to preserve and conserve. conserve water usage, recycle, reuse... put off the lights when not in use, etc... if you can walk, then walk, don't use your own vehicle. we should start at our home, office and community. let us preserve what is left to us. conserve, preserve and the earth will be saved. this is the only home we have. let us protect our home.
