There's a German standup comedian (Volker Pispers) who did a bit about this. It goes a bit like this: People always think that nature is so efficient. But nature doesn't optimize. Nature is lazy and does as little work as possible. You'll never see a lion hunt down a zebra and then go like "Okay, that took me 30 minutes, so I could do 10 more zebras today before dusk". He'll eat part of the zebra, leave the rest for the hyenas, and then spend the rest of the day basking in the sun.
