Summer Reading Post: Global Water Supplies: Are They Sustainable?
We are having one of the most glorious summers I can remember in a long time. Our days have been mild and our rainfall has been above average. It is July and we are only now seeing about 90 degree days. I hope you all are enjoying your break as much as I am. I have had the opportunity to work on some interesting projects this summer, one of which is to help collate some information on our county’s water quality and quantity. Get this:
The natural origin of the fresh water we use on a daily basis is limited to only one percent of the world’s water. Nearly 97% of the world’s water is salty or otherwise undrinkable, and the other two percent is locked in ice caps and glaciers:
• If five gallons represented all the water in the world – 34 tablespoons would represent water that was not ocean;
• Of the 34 tablespoons, 26 tablespoons would represent ice caps and glaciers;
• The remaining 8 tablespoons would represent water we can use for agricultural, residential, manufacturing, community, and personal needs.3
Water makes up almost two-thirds of the human body and 70 percent of the brain. The average daily requirement for water in the United States is about 341 billion gallons. We use one percent (3.4 billion gallons) in our homes and yards each day. On average, each of us uses almost 100 gallons of water a day including bathing, toiletry, cooking, cleaning, laundry and other non-drinking purposes. Americans drink more than one billion glasses of tap water per day. If we think of water as a precious resource, necessary for our survival as organisms, our focus on conserving water is emphasized.
This information above is from a brochure published by the Environmental Protection Agency called Source Water Protection: It’s In Our Hands. It made me start thinking about global water supplies. Will we always have adequate water supplies?
Consider these questions while reading the following article:
• How much water do people need?
• How abundant are world supplies of clean water?
• How much water is used in agriculture?
• Who provides the world’s water?
• What effects will population growth and development have on water supplies?
• How could disagreements over water lead to conflicts among nations?
• What effects will climate change have on water supplies?
One in six of the planet’s 6.4 billion people presently lack access to safe water, and a least 2.4 billion do no have access to adequate sanitation. Water demand is projected to grown by 40% over the next twenty years.
Answer one or all of the following questions:
1. How has climate change impacted global water supplies?
2. Why is it so important for individuals to have access to clean water supplies?
3. In your own words, put together a brief plan of how you might assist impoverished countries develop a program that ensures access to clean safe water?
Be thankful you are living in Berkeley Springs this summer. You could live in California, the state is literally on fire or you could be living in the Sudan.
