Everyone can do one small thing to help. Many can do lots of things to help. Some of us can do vast amounts of things to help. Help what? Slow the changing climate so that life can adapt. There is no harm in trying. Do something. Buy glass. Try & avoid plastics. Replace that lawn. Buy electric as opposed to petroleum energy. Remove that swimming pool in Arizona. Compost your shredded paper. Remove invasive plant species. Plant a native tree, a patch of prairie flowers. Save those 150 year old burr oaks. And most of all, stop contributing to over population of humans infecting the planet.
