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.

When it comes to trying to manage how our entire planet-wide market and all the people and businesses in it deal with nature and our natural resources - we first and foremost need to change the incentives.

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.

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.

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.

Whatever my current beliefs are, on any topic, they're all open to being changed by the right facts and the right evidence.

You have to be able to generate usable energy without greenhouse gas emissions and you have to be able to do it cheaply if you want people to choose that approach.
