We are now heading down a centuries-long path toward increasing the productivity of our natural capital - the resource systems upon which we depend to live - instead of our human capital.

We assume that everything's becoming more efficient and in an immediate sense that's true our lives are better in many ways. But that improvement has been gained through a massively inefficient use of natural resources.

Meat is a wasteful use of water and creates a lot of greenhouse gases. It puts enormous pressure on the world's resources. A vegetarian diet is better.
