The issue of the lack of fresh drinking water in developing nations is most related to overpopulation.

Explanation:

The lack of fresh drinking water is not only due to its rapid depletion, but is also related to the growing pollution of fresh drinking water with growing pollution. The population growth in most developing countries is unregulated. Moreover, water management mechanisms are also not much sound. Lately, overpopulation of developing nations has resulted in severe water scarcities in such countries. Countries like India and Bangladesh can be looked at as an example of the same.
