BIODIVERSITY refers to the variety of species in a specific area increases as one moves toward the equator (WHY?)

Why is biodiversity important?

According to ecologists… …without it, we will not survive.

BIODIVERSITY supports many basic natural services for humans, such as fresh water, fertile soil and clean air helps pollinate our flowers and crops, clean up our waste and put food on the table
