Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.

Polio's pretty special because once you get an eradication, you no longer have to spend money on it; it's just there as a gift for the rest of time.

When you want to do your homework, fill out your tax return, or see all the choices for a trip you want to take, you need a full-size screen.

If you're using first-class land for biofuels, then you're competing with the growing of food. And so you're actually spiking food prices by moving energy production into agriculture.

The most interesting biofuel efforts avoid using land that's expensive and has high opportunity costs. They do this by getting onto other types of land, or taking advantage of byproducts that aren't used in the food chain today, or by intercropping.

A bad strategy will fail no matter how good your information is. And lame execution will stymie a good strategy. If you do enough things poorly, you'll go out of business.
