There are many regions around the globe that contain the majority of living species. These centers of species richness are usually situated in the tropics, or along the margins of the tropics. Their study has revealed a number of characteristics that allow so many species to co-exist.

We call the character of measuring multiple species within a certain area, biodiversity, simply put, "biological diversity". There are regions of land and sea that contain the majority of living species on earth. There are other regions that are very low in biodiversity. These latter regions are depauperate, or impoverished, having very few species. Polar regions and most deserts of the world are depauperate. Unfortunately, humans have been creating regions of low biodiversity throughout recorded history. Paleontological evidence indicates humans have been causing species extinction as long as we have been walking the earth. Today humanity is causing an unprecedented extinction of species throughout the earth.

This lecture will discuss the factors that generate high biodiversity, why high biodiversity is important, and how it allows life to survive on earth. The lecture will also discuss local centers of biodiversity, their importance and value, and some recommendations on how we might conserve and protect species diversity that enriches our region of Florida.
