Pollution of rivers, lakes and seas is a major concern for people who seek to protect the environment. What are the possible causes of water pollution, and what effects does this have on animal life and human society? Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Pollution of

water

bodies

is one of the main environmental challenges that faces society currently. As all know 70% of

this

planet is

water

, but unfortunately, we are not taking care properly of

this

vital resource and the reason is because many economic

activities

have contributed to contaminate indiscriminately our lakes, rivers, streams and ocean affecting negatively

wildlife

, ecosystems even human life. Within the main reasons to pollute the

water

bodies

we can find: industrial

activities

, mining, pesticides and fertilizers, etc. Regarding the industrial

activities

, big companies release to the rivers and oceans chemistry waste that mixed with the

water

produce the destruction of ecosystems and

wildlife

.

Also

these

activities

release to the air carbon dioxide that combined with the vapor of

water

produce acid rainfall. Mining is

also

one of the most dangerous

activities

that contaminate the

water

because not only the soil is removed and contaminate rivers and lakes, but the coal extracted

also

release dangerous particles with the same negative effects for native species of amphibians, fishes which become carriers and transmit

this

waste to the humans. The indiscriminate usage of pesticide and fertilizers to protect the crops from bacteria and plagues is another cause of contamination of

water

bodies

. The chemistry components of these substances mixed with the

water

is capable to kill

wildlife

and affect negatively complete ecosystems.

Also

we have the oil leakage in oceans.

This

oil layer is very destructive and hard to remove from the

water

bodies

affecting a wide range of

wildlife

such

as whales, turtles, coral reef, etc.

Also

the effects due to

this

kind of pollution can take over 100 years to overcome. Despite of

this

hard reality, the efforts to overcome

this

situation have been carried out by many people and organizations interested in protect the natural resources, mainly the

water

bodies

because we have

finally

understand that without

water

there is no life in the planet. These efforts are represented by the application of certain alternatives to avoid the spreading of sewage and other dangerous chemistry and toxic wastes,

for instance

: the industrial treatment in which the levels of pollution of sewage is decrease through chemical processes.
