WIKI WATER QUALITY AND ECOLOGY
Liquid water is the difference between frozen dead Mars, hot dead Venus and the vibrant, life filled Earth. Go to a site like http://www.africam.co.za/ and you will see that the video cameras (cams) are set around water holes because most wildlife will come to the water holes sooner or later. Access to fresh water is essential for land based animals. It is essential for human life as well. Humans can only go a couple days without water but can go weeks without food. Water is a commodity that has social, economic and political consequences.
