I attempt to look out for the earth as a whole, although I don't devote much time to it because no one is interested in the subject. Most people prefer to look at only a small part of the earth situation. For example, the diagrams produced by the global warming crowd totally ignore the huge amounts of solar energy used in the biosphere. All the energy we use to move our bodies by walking and picking things up comes from the sun. Plants convert solar radiation into the electron bonds that hold complex carbon molecules together. Humans and other animals can use this energy. The sun is also the original source of the substantial amount of energy that evporates water from the oceans and moves it thousands of miles inland.
