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

We don't have good global policies in place for climate.

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.

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.

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

By focusing on teaching businesses about the ROI they can achieve by preserving and investing in nature, you're expanding the scope of the impact you can have.

We have climate change caused by greenhouse gas emissions, mostly from human power and transportation infrastructure. At the same time, we have 2 billion people who live in energy poverty.
