Naturally, Fidelity wanted readers to think about financial
investment opportunities, such as new technologies to produce fresh water in
areas that need it. Instead, I thought about how water affects our daily lives. Few people in West St. Louis County think of fresh water as a problem,
not even in the drought we have now. Not with the Missouri and Mississippi
Rivers in our backyards, so to speak. If you stand on the bank of either river and watch the
water flowing by it seems almost limitless.
When we brush our teeth we use one gallon. A ten-minute
shower uses about 25 gallons. A toilet flush takes between one and three
gallons. Washing your hands or face takes one gallon. About 100 gallons of
water are needed to make one cotton shirt. Producing one pound of wheat takes
80 gallons. (Source: http://ga2.er.usgs.gov/edu/sq3action.cfm)
Although West County residents seldom think about water
shortages, we are not insulated from fresh water supply problems. Witness what
has been happening over the last thirty years on the Great Plains. Also known
as America’s Breadbasket, the Great Plains is one of the world’s most fertile and
productive agricultural regions. Agriculture there, from which all Americans
benefit in terms of food products, is largely sustained by groundwater
irrigation from the Ogallala Aquifer. That massive underground system of nearly
175,000 square miles stretches from central Texas through southern South
Dakota. Nearly 30 percent of all irrigated land in the U.S. uses groundwater
from the Ogallala.
Only problem is, that Aquifer has been depleted over the
past several decades by excessive withdrawals for crop irrigation. You might
have seen the tell-tale green circles when you fly over the region. That
situation isn’t critical yet but needs to be carefully analyzed and viable
options pursued before it’s too late.
No matter what your opinion may be on environmental issues
in general, water use today and in the near-term future is an important
challenge because of present-day tight supply and looming population growth.
And here you might think about the one billion plus people in China who are
getting used to a diet higher in animal protein, especially beef, and remember
Fidelity Investment’s statistic of 635 gallons per hamburger and the 35 gallons used to produce each cup of coffee.
