How do you put a dollar value on something that in some ways is priceless? Like the Mona Lisa? Or biodiversity?

Bruce Hungate is the director of the Center for Ecosystem Science and Society at Northern Arizona University and lead author of a paper on the economic value of soil carbon storage. The paper was published in "Science Advances."
