Stanford Biologist Sees Money in Preservation

Gretchen Daily wants to protect the planet by convincing governments and big investors there's money to be made - or at least saved - in preserving nature instead of exploiting it.

It's a fresh approach to conservation that is drawing international attention to this unpretentious Stanford biologist who has garnered some of the world's most prestigious scientific honors. At its most basic, Daily is figuring out how to put a price tag on the natural world. And colleagues say she has done what many scientists have not: connected theory to practice.
