1 Tropical Andes Biodiversity Hotspot The richest and most diverse region on Earth, the Tropical Andes region contains about a sixth of all plant life in less than 1 percent of the world s land area.2  One of the more unique plant species is an Andean bromeliad that require 100 years to mature. But the relationship between people and biodiversity is not simply one where more people lead to greater impacts on biodiversity. 2  Human population density among hotspots varies widely, from four people per km to as many as 336 people per km (in Japan). 3  Hotspots are also notable centers of violent conflict.
