You compost and recycle. You buy organic local goods. You ride your bike to work, and you shower in under five minutes. You make sustainable choices, because you know that while we have been able to run on oil and gas for a long time, accomplishing a great many things, these resources are rapidly depleting. We must now instead find sustainable renewable energy from more abundant natural resources like the sun and wind. However, as Señor Ghandi so wisely said if we must "be the change [we] wish to see in the world," supporting Mother Earth begins at the most local ecosystem we know.
