Ecological health is the most important thing to keep all ecosystems and our earth clean and beautiful. All these ecosystems are influenced by human activities. These ecosystems need us to stop polluting and damaging all organisms' habitats. The fact that aquatic ecosystems cover such a large part of the earth means that it's pretty important. As I stated in the introduction, all of these ecosystems are vulnerable to climate change, pollution, and even overfishing. All of these ecosystems have very different diversities such as the animals or organisms you might find in that ecosystem. Each ecosystem has different ways to maintain ecosystem health to improve the quality of life and quantity of organisms. All in all I think aquatic ecosystems play a huge role in our daily lives and without them humans might never have existed; we may not even have ever had water or food from animals and organisms from them
