Poor water quality means water pollution, it means that one or more substances have accumulated in the water to the point that it causes problems for animals or people, there are many causes in our world that need to be solved by assistance health or by humanity The world will be in chaos, animals will be extinct, and diseases that cannot be cured will spread among humans. 40% of water has been polluted and the mortality rate in human civilization will continue to increase until extinction. The effects of water pollution are multiple. They include poisonous drinking water, poisonous edible animals, imbalanced river and lake ecosystems that can no longer support full biological diversity, increased acid rain, and many other effects.
