It is estimated that 100 million animals die every year due to water pollution.
In addition, ocean pollution affects 1,000 species of marine animals. However, these are rough estimates because it is almost impossible to calculate the exact number of animals killed by water pollution. Polluted water can pose a serious threat to both animals and humans. Animals and plants living in this water often die from this pollution.
Even if a particular animal did not die from pollution, it would likely die from changes in the food chain. Animals and people who drink water from this source can contract bacteria and diseases that are often carried in this water.
