A population is all the organisms that both belong to the same species and live in the same geographical area. The area that is used to define the population is such that inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas. Normally breeding is substantially more common within the area than across the border.

The population of world is going bigger and bigger. Some population is leading us to droughts like "AFRICA".

We have to thnk ways to minimize it!!!!!!!!!!!!
