The more widely you can spread this notion of achieving ROI by preserving and improving ecosystems, the better.

I was much more of a naïve techno-optimist than I am now. I still believe that technology can help us come out of this situation with a richer humanity with less impact on the planet, but now I think it has to be paired with effective policy in order to achieve that.

Ozone and climate are global issues, and it's hard to find a way in which the benefits of shutting down carbon emissions are going to pay for themselves for any given power-plant, say.

Often we need to use policy to level the playing field, or to be sure that a technology is managed in a responsible way.

TNC was once limited by the resources it could directly marshal to buy land. But teaching people a new idea is incredibly more scalable.

Unfortunately, in the environment, I don't see as much willingness to invest heavily in R&D as I do in consumer technology. And that's a pity.
