Sustainable Water November 28 & 29, 2012

Water is in every living thing. Our body is nearly 65% water. An ear of corn is nearly 70% water, a potato is about 80%, and a tomato is about 95%. In order for living things to carry out life processes, we must keep our water supply clean and healthy. We can live without food for two months, but we cannot live without water for more than a week. Why Is Water Important ? Life is not possible without water!

Drinking Agriculture Washing Transportation Recreation Hydroelectricity Industrial uses Food Processing Scientific/Chemical uses What do we use it for?

How Much Do We Have?

70% of the earth is water 97% is in the oceans The fresh water available for us to use is about 3% of the earth's water supply. Three-fourths of the fresh water is unavailable because it is in icecaps and other glaciers. Let's look at the numbers!

Americans use more than 400 billion gallons of water in one day, more than our total oil consumption in one year! More Numbers... Every day 5,000 children die from diseases associated with inadequate water supply, sanitation and hygiene. All of which are preventable

DO WE HAVE ENOUGH? Yes, we do! But... We need to use it more wisely!

Sustainability means providing an adequate and reliable water supply of desired quality – now and for future generations – in a manner that integrates economic growth, environmental protection and social development. Sustainable Water

What Can We Do?

How are humans affecting the Hydrological System, and contributing to the depletion of fresh water? List 4 things. What can we do to change what is happening to our fresh water supply? If this continues, what do you think will happen? Blue Gold: World Water Wars

Desalination PROS: Creates clean water Better for the earth than pipelines and dams CONS: Energy Pollution Money Location Hurts marine life

Is pumping and transporting water a good or bad thing?

Aral Sea

1. What are humans doing to affect the hydrological system, and how is it affecting the depletion of the freshwater supply? List 4 things. 2. What can we do to change what is happening to our water supply? 3. If we continue to use the water the way we are currently, what do you think will happen?

Now research water in your MUN country. Write a one- paragraph solution on how your MUN country could solve some of the water problems that exist there. Research!
