1. Planet earth or Planet water?
Without water, life could not exist. Because water is essential to all life, we
must manage it intelligently and carefully. We think there is plenty of it –
oceans, lakes, rivers, and streams. It may even seem as though we have
more water than we need. Unfortunately, the reality is not the case. Water
is essential to people in more ways than you might think. We need water
for cooking, bathing, transportation and recreation. We eat aquatic plants
and animals. We use water to irrigate our crops, and to manufacture
products. Most of the water on Earth (97 percent) is salt water stored in
oceans. Only about three percent of the Earth’s water is fresh water, and
most of that is locked up in ice caps and glaciers. There will never be more
water on Earth than there is now. The same water is simply recycled over
and over again. Just think – the water we are using now is the very same
water the dinosaurs used to drink millions of years ago.
