To more or less quickly elaborate on what you just asked, when you look at the environment, you can't just separate that from economics, but you also can't separate economics from the environment.
If you look at the effects of one thing, on the one hand it may be economically viable to do something, but on a health level, it may not be a viable alternative, with long-term health effects—diabetes, heart disease, different other factors in there—or if you lose a single species but gain that one year or that bottom line on your business.
For some of those things in there, I think it's very important, when we're looking at that.... You know, we went from an age of technology to knowledge, and I think all forms of knowledge are necessary in order for us to actually achieve what's considered a sustainable economy and a sustainable environment.
