"The Earth isn't dying, it's being killed, and those who are killing it have names and addresses."

  "The Earth" isn't being killed. Human activity (emissions of CO2, toxic metals, persistent organic toxics and so on, and deforestation, soil depletion, etc) is changing evolutionary selection parameters in myriad ways for myriad lifeforms. That is indeed unprecedented for a single species. However, it's happened before. For example, the emergence of photosynthesis profoundly altered the atmosphere. That brought extinction for most existing species (anaerobic bacteria). But it obviously set up the game for multicellular life. Anyway, my point is that change is normal. Maybe we humans will drive ourselves extinct. But I rather doubt that. Most other species won't be so lucky, however.
