Deset plants live clever.

I heard a speech by a woman who, when she was in school learning to be a civil engineer, had a job monitoring a landfill. The result of that job is that any object that comes into her life or that she might think of taking into her life, she thinks about her longterm relationship with that object. Object as in soda bottle. Object as in wrapping. She thinks hard about it all. She can't throw stuff away. She has visited away, and studied away in detail.

Desert plants don't look at their resources and go, "Oh, well," and drop them wherever.
