"Number 8: The ecosystem collapses. Last July, in Science, the journal Science, 19 oceanographers published a very very unusual article — it wasn’t really a research report, it was a screed. They said, we’ve been looking at the oceans for a long time now, and we wanna tell you they’re not in trouble, they’re near collapse. Many other ecosystems on Earth are in real, real danger. We’re living in a time of mass extinctions that exceeds the fossil record by a factor of 10,000. We have lost 25% of the unique species in Hawaii in the last 20 years, California is expected to lose 25% of its species in the next 40 years. Somewhere in the Amazon forest is the marginal tree. You cut down that tree, the rain forest collapses as an ecosystem. There’s really a tree like that out there. That’s really what it comes to. And when that ecosystem collapses, it could take a major ecosystem with it, like our atmosphere."
