Pollution of rivers
The river pollution is a problem older than the pollution, but with the increasing population of the cities that were born on the banks of the same, the volume of both organic waste, sewage product, including chemicals as consequences of industrial development, increased so that the waters are affected the same so that its composition is no longer natural, affecting both fauna and flora that eats the same as the humans who drink.
The examples in the world of rivers that have suffered irreparable damage and provocation are many of them usually is due to the installation priority industries and factories that generate jobs, but their waste production cycle. The big companies that started mainly in Europe, after having caused damage to their countries and that they themselves may legislate to prevent installation, migrated to underdeveloped countries where there were no such requirements and laws that put a framework for the installation of these plants, causing damage in these countries again.
The example of this, we are experiencing at this stage of civilization in Eastern countries, mainly in China, where industrial development impetuous, has caused environmental impacts in rivers that have caused the transfer of large populations which inhabited the shores traditional extracted from the same river the necessities of life, both from the standpoint of food and income generation to cover other basic needs.
The manufactured and installed in industries located along the banks of these rivers for use, go paradox, the waters of the same for their production cycle, so as to have low costs, then punish the same shipment on track all types of pollutants and chemicals harmful to animal life existing in it, and killing much of it. In this way, and fishing decreases, the water can not drink safely and those who lived it have to migrate to the negative consequences this entails.
Another factor that negatively influences the survival of the rivers, mainly in countries with high agricultural production, and the indiscriminate use of insecticides without established protocols and herbicides, which are often scattered by aircraft spraying, falling part of them in rivers, adding to this the washing of the remains have also produced fish kills in waterways used.
Contamination with the sewer without having a treatment prior to arrival at the river, is very common in developing countries, causing an excessive increase in the number of coliforms with subsequent development of disease. They are famous rivers like the Ganges in India where religious grounds is customary to use it for rituals such as the morgue for the dead in them, defying the heavy pollution of wastewater.
