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.

[@jnzk6467]

😂 what in the world

[@nosleepdelirium1214]

how do we know it is the worst mass extinction when we can't possibly compare to the other extinction events that happened millions of years ago? we can compare to fossil record which is not complete, it will never show everything the way we can see it in real time today.

[@joeyama2259]

I hope I can too

[@afiyasiddiqui7311]

Yes it was helpful
