Many of the technologies we've invented are necessary to keep 6.5 billion people alive. We can't go back from that, so we need to decarbonize really rapidly.

You can never properly predict the future as it really turns out. So you are doing something a little different when you write science fiction. You are trying to take a different perspective on now.

Life is insanely robust, though we can make species go extinct, and this is the bad thing. So I always make the point that you can't say, 'Is it too late?' That is the terrible question, because either answer promotes inaction. If it's too late, you don't need to act; if it's not too late, you don't need to act.

If the amount of money going into the war economy were invested in landscape restoration, we would be in a far more positive position. It may get a little dire before we pull together, but I think when the prosperous nations, and in particular the U.S., realize they're wrecking their own kids' lives, there will be a mass change in value.

If a doctor said you had stomach cancer, would you consult Rush Limbaugh for a second opinion? Of course, that sounds like nonsense, but many Americans have no qualms about listening to political commentators and untrained activists when it comes to even more complex scientific questions.

I suggest Substituting Inedible Nurturance, or SIN. Don't replace overeating with virtuous work or exercise; instead, make a list of things you love, from watching TV to hanging out with favorite people.

I do a lot of weight training, and my workouts are intense, which include cardios, core body workouts, and functional training.

Americans want jobs. They want affordable health insurance. They want an education.
