Why should we care about Global Warming?

This beautiful blue-green planet on which we live is, as far as scientists can tell, the only world that can sustain life. The atmosphere has the perfect mix of air that we need to breathe and which trees and plants need for survival.

The earth is the perfect distance from the sun, allowing ideal temperatures to enable millions of species of animals and plants.  The vast oceans are kept at a temperature where so many species of fish are able to survive. In short, the planet Earth supports every species in the food chain, right from the bottom to the top.

Immense problems would be created if the planet were to cool permanently - even a few degrees. As an example, can you imagine what might happen if snow came earlier and stayed later in the Midwest of the USA? Production of grain grown there would decrease sharply, creating a huge shortage of meat as well as a grain famine.

More importantly, what would happen if the earth were to heat up several degrees permanently? The ocean water temperature would no longer support plankton, which support fish, which support birds, and so on up the food chain.

The weather would change beyond recognition; as the atmosphere heats, rivers and oceans would evaporate. The levels of carbon dioxide and methane in the atmosphere would increase, making the quality of our air- the air that you and I take for granted every day - unsafe to breathe.

Every degree that our atmosphere changes is harmful to the life cycle of all humankind in some way. Think Globally!
