Two out of every five people on Earth today owe their lives to the higher crop outputs that fertilizer has made possible.

Oh, I think there are a lot of people who would be buying and selling online today that go up there and they get the information, but then when it comes time to type in their credit card they think twice because they're not sure about how that might get out and what that might mean for them.

The part of uranium that's fissile - when you hit it with a neutron, it splits in two - is about 0.7%. The reactors we have today are burning that 0.7%.

People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.

Almost every way we make electricity today, except for the emerging renewables and nuclear, puts out CO2. And so, what we're going to have to do at a global scale, is create a new system. And so, we need energy miracles.

There are two sides to every story, and sometimes three, four, and five.
