What you can do to help our earth: 
1. Turn off the lights when not using
2. Reduce, resuse, recycle
3. Do not litter
4. When brushing your teeth, turn off the water.
5. Walk or ride your bike when you can; try not to drive.
We abuse land because we regard it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect.
~Aldo Leopold, A Sand County Almanac
