The correct answer is Biodiversity.

Biodiversity is well consistent with the United international locations environment Programme or additionally referred to as UNEP, biodiversity normally measures version on the genetic, the species, and the surroundings degree. Terrestrial biodiversity has a tendency to be more close to the equator, which seems to be the result of the nice and cozy weather and excessive primary productiveness. Biodiversity is not dispensed lightly on the planet, and is richest inside the tropics.
