How might biodiversity be important to an ecosystem's health and stability?

We rely on many different species as food or sources of medicine so it is important to the health of future generations that organisms that supply us with these resources are not lost. This is an example of the importance of biodiversity on a global scale.

Ecosystems with higher biodiversity are more stable as they can easily adjust to changes. They also have fewer species that depend on just one another for food, shelter and maintaining their environment
