Although we often think our planet will
never fail to provide us with enough drinking water, this may not be
true, at least not if we continue adding people and polluting our
water. Even today some people pay more for bottled water than they
do for gas for their car.
It's not just drinking water we need,
we also use water in agriculture; to grow plants, and for our
livestock animals. As we add more people to what many would say is
an already overpopulated planet, we will continue to require more
fresh water.
How Much Fresh Water is there?
About 98% of our water is in the
oceans, leave 2 % as fresh water, of which 1.6% is frozen in icecaps
and glaciers. 0.36% is ground water, leaving only 0.036% available
to us in our rivers, lakes, and streams. Other water is in cloud
form, or actually in the bodies of animals, and in plants.
Many people look naively at the oceans
and think we have an unlimited amount of water. Even those that are
smart enough to realize our fresh water resources are at risk
sometimes are ignorant to the risks that our oceans face, and the
problems of relying on ocean water to solve the impending crisis of
not having enough fresh drinking water. In other words desalinization
plants may not be the answer if we continue to add to the population
at the rate we currently are.
The Water Crisis will be Fueled by Human Overpopulation
Today we live in a paradox, we are
finding ways of bringing fresh, safe, drinking water to more people,
but industrialization is resulting in more and more chemicals finding
their way into streams, rivers, and eventually the ocean. More
people means more demand for fresh water, and it means more people
polluting the water we have.
People in some nations (such as El
Salvador) are spending over 10% of their total income on safe
drinking water. In a world with a growing population and increased
pollution, water is becoming a premium resource. For now it might
seem that we are improving the supply of fresh water to people who
have not had it in the past, but at the same rate we keep adding
people to the planet, and making demands of a valuable resource.
Terra Nova got it Wrong
If you have been watching FOX network
(American TV) show Terra Nova, you will have seen an overpopulated,
over polluted planet in the year 2149. The show is fun to watch but
has some flaws, one flaw being that while the people in 2149 live in
domed cities and require masks to breath the air they sent people
back into the past (through a portal in time to the time of the
dinosaurs) to rape the planet for minerals. It seems far more likely
to me that the resources they would most want would be fresh drinking
water and perhaps even a few dinosaurs to feed all the people.
A Wake Up Call
I just know somebody who is reading
this is probably thinking: “What about desalinization?”, Sure we
can remove salt from the sea, but desalinization plants cost money
how far inland will we pump the water, how much will it cost the
consumer, will coastal countries pump water inland to countries that
do not have coastlines?

Have you ever heard of the Aral Sea?
If you haven't it is probably because the sea barely exists anymore
compared it to what it was years ago. Although it is in a
state of recovery now (due to pressure to save the Aral Sea) it was
almost gone, due to water being diverted from it for agricultural
purposes. It is still mostly too salty for life (having become salty
due to the lack of fresh water reaching it for years). It is
alarming that so few people have even heard of it since, at one time, the
Aral Sea was one of the four largest lakes in the world.
As such I suggest that the most
valuable substance on earth is not oil, uranium, gold, or silver, but
is one thing we take for granted: Fresh water.
Brenda, I hope it is not too late for us to protect the fresh water of the world. I am afraid that water will be more valuable than gold in the future. It is so sad considering our planet is 75% water and then we don't have enough water to drink. I hope we can all work together to fix the future fresh water shortage.
