If you haven’t sold your soul, you have to be willing to criticize the people you admire on your, quote, side, and my owning my bias by going out there onstage with Donald Trump and saying, “I’m voting for him, and you should, too” is a bonus when it comes to my credibility

In the past, human progress had to come at the cost of the environment. If we wanted energy, we had to burn wood or we had to burn fossil fuels. If we wanted to grow more food, we had to expand farmland, often at the cost of forests. But technology and innovation means we're very quickly decoupling these impacts, such that this conflict is no longer true.
