show that if the number of dams are increased, the cultivated around rivers
areas will fade away.
On the other hand, these floods like I
indicated previous paragraph cause deterioration of human settlements. For
instance, the Teton Dam, which was an earthen dam on the Teton River in Idaho,
United States, suffered a catastrophic failure on June 5, 1976, as it was
filling with for the first time. The collapse of
the dam resulted in the deaths of 11 people and 13,000 cattle. The
dam cost about $100 million to build and the federal government paid over $300
million in claims related to its failure. Moreover, because construction of a dam takes up a large chunk
of land, it forces relocation of humans. A quotation of The Guardian article, which was released
in 2010, can be exemplified this case:
hydroelectric dams being built or planned in remote areas of Brazil, Ethiopia,
Malaysia, Peru and Guyana will devastate tribal communities by forcing people
off their land or destroying hunting and fishing grounds, according to a report
global assessment of the impact of the dams on tribes suggests more than
300,000 indigenous people could be pushed towards economic ruin and, in the
case of some isolated Brazilian groups, to extinction.
Thus, we can say that hydroelectric power
plants just conduce that rich guys fill their pockets with money.
However, against these propositions, people say that hydroelectric power
is cheaper than its alternatives and it does not pollute air, water or soil.
Yes hydropower is cheaper than its alternatives, but when it harms the soil, we
will not be able to turn back to those days, and yes it has not visible
pollution, but it deteriorates the environment in long time. They cannot see
the corruption, but it goes on. So when they assert these claims, they are
Most people think that hydroelectric
plants are innocent, because there is no pollutant or wasted water. However, they
cannot understand that hydropower dams deteriorate habitats of animals and
humans, and also decrease productivity on agricultural areas. Every year
because of the dam failures thousands of people die and become homeless.
However, the number of dams increases, since thanks to the indifferent attitude
of society, governments keep on permitting to construct new ones. Even if there
are some environmental movements like the International Anti-Dam Movement,
researches and movements on the issue are still insufficient.
