In spite the fact
that it looks so abundant, almost endless, learn how many water
is available for human consumption.
It is widely known that 2/3 of the planet is water, being that
from all this water:
- 97% it’s salt water
- 2% is frozen in the poles, and
- only 1% of all the water in the planet is available to human
consumption.
Did you know that 14% of the world fresh water is found in Brazil?
We are a very rich country as far as water is concerned, but are
also facing a huge problem of distribution, since 80% of our fresh
water is in the Amazon.
Brazil has the greatest underground water reserves in the world.
Nevertheless, we have extremely critical areas, with shortage
and rationing, because of non equal distribution on this resource,
springs and rivers pollution, uncontrolled soil occupation, and
waste.
Recent studies shows that over 10 million people die every year
due to diseases transmittable by contaminated water, as typhus,
dengue, infections, hepatitis and cholera. The water pollution
is responsible, itself, for 33% of deaths around the world.
68% of hospital beds are occupied with illness caused by bad quality
water.
Years ago, water resources used to have a much higher quality
than they do now-a-days. The population growth made the water
pollution levels increase, moving some governments towards a greater
concern about this problem. It was necessary to enlarge the use
of decontaminating agents in the water, such as aluminum sulfate,
chlorine, among others. The chlorine, combined with organic materials
found in water, like wooden wastes, leaves, rot animals, etc.,
produces another element known as Trihalometano, highly carcinogenic.
The chlorine, extremely disagreeable to smell and taste, also
stops the cakes and bread growth, killing the micro-organisms
alive in baking powder.
Industrial wastes, frequently loaded with high levels of copper,
chrome, nickel, cadmium and other metals, thrown on rivers, pesticides
and other kinds of poison used in agricultural activities, which
infiltrate in the soil, also contribute to the underground water
pollution, jeopardizing more and more the quality of our rivers
and population health.
