Basically, I get paid to be crazy. I get paid to believe I'm someone else, live in a completely false reality, and believe it's real. And that's a little scary. And I do it to the best of my ability. But it's kind of like swimming out to sea. You have to leave enough energy to swim back, and sometimes you get scared you swam too far.

We see evidence that lakes and forests and wetlands can have different equilibria - so you have a savanna system that may be stable and thriving, but it can also tip over and become an arid steppe if pushed too far by warming, land degradation, and biodiversity loss.
