As you probably have both
read and heard, shortages of safe drinking water exist in many places around
the world. The World
Health Organization reports[1]
“at least 2 billion people use a drinking water source contaminated with faeces
[feces],” and also states that “By 2025, half of the world’s population will be
living in water-stressed areas.”
In recent months numerous
articles have reported on water shortages that exist in various places
worldwide, including one from Reuters.[2] A list of “10 Cities Most
at Risk of Running Out of Water” is provided by US
News & World Report.[3] India is one of the
countries already experiencing major water shortages, as reported by CNN[4]
and other news sources.
Shortage Is of Drinking Water, Not Water Overall
It
is important to remember that although the supply of drinking water is
declining, there is no shortage of water overall. The oceans contain a huge
quantity of salt water.
A
2008
Scientific American article[5]
discusses why we don’t desalinate more ocean water to alleviate drinking water
shortages. However, despite issues with desalination, it is becoming much more
common.
Two
big problems with desalination are its cost and the environmental damage it
causes. A January
2019 Reuters piece[6]
cites a UN study discussing environmental damage from the thousands of desalination
plants in the world. However, Columbia
University researchers reported[7]
in May 2019 that they had developed a new desalination process that may make
water desalination more feasible on a large scale.
Desalination is already
widely used. A USGS
webpage[8]
states that “According to the International Desalination Association, in June
2015, 18,426 desalination plants operated worldwide, producing 86.8 million
cubic meters per day, providing water for 300 million people.” And, an International Desalination Association
webpage[9]
states there are now 20,516 “desalination plants worldwide.”
Suggestions for Dealing With Water Shortages
·
As water desalination becomes cheaper, more
environmentally friendly, and more widespread, it can do much to alleviate water
shortages.
·
We can do more to conserve water. Let’s avoid
wasting it.
·
Let’s devote more time, talent, and money to
research into alleviating water shortages and less into military weaponry and
wars. But, that’s easier written than attained.
·
Agriculture uses a huge amount of water to
provide for livestock and the crops that we humans eat. Changing to a vegan
diet that eliminates the need for huge quantities of cows, pigs, sheep,
chickens, etc. could greatly reduce water usage according to a Guardian
article[10]
and other sources.
·
Reducing population growth through more
sexual abstinence and/or consistent proper use of contraceptives could greatly
reduce the increase in water consumption that is forecast for future years.
·
Also, we need to plant billions more trees
worldwide. According to a piece
on the North Carolina State University website[11]
“Trees . . . help increase ground water recharge, reduce soil erosion and storm
water run-off thus reducing the amount of water we consume and the need for new
water treatment plant and storm water structures.”
Closing Thoughts
I think cheaper more environmentally friendly desalination on a large scale, slower population growth, persons eating vegan diets, and a massive increase in tree planting would go a long way toward solving our water problems. Progress is being made in all these areas and in others, but we have a long way to go. What do you think?
