Having studied biology really helped me a lot because I quickly understand how biological systems work, and how they fail, and the tragedy of when they fail, because we are dealing with life systems, and when we hear that a species has become extinct, or is threatened, you realize that this could mean that this species will disappear from the face of the earth forever! So that understanding really gives you energy to do something to save it.

There is no reason why a company like Monsanto, for example, that is pushing GMOs, cannot go to Kenya, partner with the university, partner with the research institutions, and try to promote - in a responsible way - advanced techniques to help farmers. But this should be done in such a way that the farmers' livelihoods are not undermined because the government is irresponsible or careless, or because it is compromised.

The issue of climate change, it really does bring home the fact that we are on one planet, and that some of the impact of what human beings do in one corner of the world is going to affect people in a distant corner of the world.
