To begin with, I've always known that I was a little bit different. And, I have a lot of relatives who own farms. I grew up in the American South where political issues and issues of justice were at the forefront. What I do now is a combination of all these factors.

The drive behind what I do is really to make sure that people don't go to bed hungry. It's not just that I have a love of diversity, it's the importance of the uses of that diversity.

To many people, 'biodiversity' is almost synonymous with the word 'nature,' and 'nature' brings to mind steamy forests and the big creatures that dwell there. Fair enough. But biodiversity is much more than that, for it encompasses not only the diversity of species, but also the diversity within species.

It is impossible to talk about slowing climate change without talking about reducing CO2 emissions. Equally, it is impossible to talk about adapting to climate change without considering how we will feed ourselves. And it is out of the question that we can adapt agriculture without conserving crop diversity.
