Technology is incredibly powerful. And in many ways, the sky is the limit in terms of what you can actually accomplish with the right science and the right technology.

Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet. One leads to ecological collapse. The other is a reversion, in many ways, to poverty.

There are really two kinds of optimism. There's the complacent, Pollyanna optimism that says "don't worry - everything will be just fine" and that allows one to just lay back and do nothing about the problems around you. Then there's what we call dynamic optimism. That's an optimism based on action.

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

You have to be willing to spend an awful lot in that R&D phase before you see the benefits. When you look at the companies that have really won customers over in technology - say, Apple and Google - you find that they spend billions of dollars on R&D each year, often spending that much on a product before they ever make a dime back in profits.

Today, our incentives aren't set up well - you can make a lot of money burning fossil fuels, digging up wetlands, pumping fossil water out of aquifers that will take 10,000 years to recharge, overfishing species in international waters that are close to collapse, and so on.

If the incentives are aligned right - towards better preservation and restoration of nature and natural resources - then you'll see a tremendous amount of activity in that direction.
