Estuaries are often highly polluted bodies of water and can be used to measure the overall health of an ecosystem. devise a logical argument for why estuaries become so polluted and provide at least 2 examples of the importance of estuaries.

The reason why estuaries have become so polluted is that humans have been piling their various wastes in them. We have introduced chemicals and many waste products that are hazardous or potentially harmful to the estuaries ecosystem.

Estuaries are very important and vital for the ecosystem. They provide two important services that ensure life. They provide water filtration and habitat protection.

I hope it helps, Regards.
