"You know, the poor people are the ones who are going to suffer the most from climate change. It's unfortunately the poor people of the world who live in tropical zones, and....that's where agricultural productivity is already barely good enough for survival. Think of people in places like Ethiopia, Somalia, Sudan. There, climate change will clearly reduce productivity without some big innovation in the seeds and the approaches."
-Bill Gates, Q&A with Technology Review
Quite an interesting Q&A session on energy, philanthropy, market incentives, and the power of innovation.
