Water is an important resource not just for humans but for all the organisms on earth. Therefore, contaminating this natural resource has dire consequences. The main reasons for water pollution are our commercial and industrial activities. All the waste effluents that reach water bodies result in water pollution. In the long run, this can cause many diseases and health hazards for us.

For instance, in Minamata City, Japan, mercury which runoff from a factory polluted the waters and the poisoning went undetected for decades. It came to notice only when the people saw their newborns had unusual birth defects. It was found that mercury runoff had contaminated the marine ecosystem, resulting in fish species ingesting the mercury. Over a period of time, mercury accumulation in fish species got transferred into human bodies that consumed contaminated fishes. This adversely affected bodily functions and caused a lot of problems for the people and their descendants. Hence, we need to take care of such issues by preventing industrial effluents which pollute our most precious resource – water.
