perform valuable ecosystem services, such as removing pollutants from the air and storing carbon,» says Steve Frank, an associate professor of entomology at North Carolina State University and co-author of the paper.
If that's just a bunch of international relations - speak to you, this is why this is important: The idea behind
ecosystem services payments is that in exchange for preserving intact (or at least not entirely degraded)
ecosystems, which
perform valuable social functions such as improving air quality, flood protection, traditional medicines, sequestering carbon emissions, et cetera, nations should be compensated.
