Our own economy tells us to take as much as we can get, right? Our own economy says, you’re going to be the most successful graduate if you go into the business world and take as much you can get. That’s not how nature works. Nature has a much simpler economy. Everything in nature takes what it needs. That’s it. You don’t see an oak tree gathering up all the resources. An oak tree takes what it needs to be the authentic oak tree it is.
– Tom Shadyac
While there is competition in nature, there are also limits to how much any one individual plant or animal can consume.
