I learned a lot of interesting stuff in this book, like rot is really important. If we didn't have rot, we wouldn't have any new growth. I learned the life cycle of rot: New growth, let's say a tree. Fungus gets into it (like mushrooms), and then the fungus and other microbes eat away at the branches core until it falls of and bes a soft log on the ground. Then, insects and other critters (ants, termites) get into the wood and eat their way through. It's their living! Then, the tree is weak and soft and will eventually become fresh soil for new things to grow. Now that I know how important rot is, I'm not unhappy about rot. It can make you brain damaged, but that's another story.
