Excreta

Excreta is the solid or liquid waste which comes out of living beings such as plants or animals. It is organic and it fertilizes the soil. There are many sanitation techniques to dispose excreta. The first technique is to dump them into the wasteland. This allows the soil to absorb the excreta and it fertilizes the soil. This is good for the plants growing on it. The second method is to allow it flow into the river. The excreta are disposed in the deep sea to avoid them from polluting the water too far and wide. However, this has led to water pollution and the habitation is getting extinct the regions of disposal.
