...what did you do for the Earth today? For my self, I am taking the bus to and from work. My lunch did not require cooking, heating up or any other expenditure of energy. Dinner will require enough to nuke leftovers but in a microwave, that's pretty quick. Last but not least, I try to respect this Earth we live on...face it folks, unless something happens in the Space programs across the globe, at this time, this is the only place we have to live. If we take care of it, it will take care of us.
