Day by day, man is responsible for the pollution.

Look at an example.

The photo shows the sewage disposal of untreated water into the rivers.

Rivers are the source of drinking water for the people living near them. The sad thing about it is the fact the these people use the water without any treatment for their daily needs.

Although there are ecological standards they are ignored without realizing that it is for their own damage. Besides polluting the river one damages the surrounding eco-system.

This can be seen in many communities in Columbia.
