Multi Purpose Things

Gotta hand it to you, Big Guy! This morning, while sitting under a coconut tree in Puerto Rico after a morning swim in the Atlantic Ocean, it occurred to me how this tree has many purposes. Not only did its leaves provide me shelter from the sun, but it is an important source of milk and food for animals, humans and probably bugs. There may be other uses for the coconut tree that I'm not aware of (since I did not create the world).

For Earth 2.0, I hope you'll err on the side of creating things with multiple purposes as opposed to one purpose -- like a golf course.
