I stand by my assertions that although you can know what happens to any individual species that you modify, you cannot be certain what will happen to the ecosystem. Also, we have a strange situation where we have malnourished fat people. It's not that we need more food. It's that we need to manage our food system better.

There really is no such thing as race. We all came from Africa. We are all of the same stardust. We are all going to live and die on the same planet, a Pale Blue Dot in the vastness of space. We have to work together.

I tell personal stories associated with aspects of the theory, and I hope they are interesting and compelling. I don't feel you're going to change a grownup's mind in one reading. People have to be exposed to scientific ideas over and over again for years. It's also not a textbook.

If you look back on all the teachers that you liked, I am sure you will find they were very entertaining.

If the Earth gets hit by an asteroid, it's game over. It's control-alt-delete for civilization.

I try to speak plainly and be sympathetic to the idea of religions where people gather in community. They get a sense of people looking out for each other. My claim is that we have a tendency to look out for each other whether or not there is a religion involved.

I hope climate science becomes the big thing. And then what I want is electrical engineers to solve the world's energy problems, energy distribution problems. I want mechanical engineers to make better transportation systems. I want chemical engineers to develop better solar panels, and so on.
