The National Geographic Magazine is a treasure trove of knowledge.

Save the Key Largo Cotton Mouse

"A cotton mouse is truly the least among us, but shouldn't we show consideration to all creatures? Or do we alter our behavior only when it's convenient, or when money isn't a factor? We live in an age where we are drilling for oil in the last, best places - when citizens allow laws to be passed that actually lower the quality of water and air. We vote based on prices at the gas pump.

Against this background, I know that a little mouse isn't a big priority. It's a battle to get anyone to pay much attention. But since the fate of humanity is tied to the rest of the Earth's species, I have to try. Everyday, I teach my children to care for the natural world, because it's humankind's gift to imagine the future and to implement change."
