Question

How will loss in biodiversity negatively affect humans?

Answer 1

We will not be able to cure some diseases

Explanation:

Think: there is a creature (coded X). If we eradicate this species, we will never see it again.

Suppose this creature has a cure for a disease but we do not know it today. If we save it, we will probably find advantage of this creature. In the future, since we saved this creature from extinction, we can benefit.
