I think the environmental movement is now so large and diverse that it's hard to talk of it as a single entity.

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.

In the food case in particular, one of the technologies that could help there - genetic technologies that could create better crops with higher yields and less need for water and fertilizer - is tremendously feared. Very little of that fear is scientifically grounded.

If you want to feed the planet and keep the forests we have, you need to be able to grow roughly twice as much food per acre around the world. How do you do that? New technology.

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.

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.

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