Ecosystem Diversity

009 - Ecosystem Diversity In this video Paul Andersen explains how biodiversity can be measured through genetic, species, or ecosystem variety on the planet. Species diversity is increased through speciation and decrease through extinction. The mechanism for speciation is evolution through natural selection. The planet provides ecosystem services at no cost to humanity. The supporting, provisioning, regulating and cultural services are all discussed in more detail. Do you speak another language?
