Biodiversity at Risk

Why is biodiversity in an ecosystem so important?

• Because it can help humans where to determine good places to develop farm land.

• Because places that have a healthy biodiversity are unaffected by major disturbances.

• Because having a high biodiversity allows ecosystems to withstand major changes.

• Because having a high biodiversity allows for fewer opportunities of competition for similar resources.
