Why is biodiversity so important?

• Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well

• Because it’s better to have only one variation of each species.

• Because it better to only have a few species on Earth.

• Honestly, I have no idea what biodiversity is!
