I just think that a much more important part of the problem we face, which was evident 10 years ago and is even more evident now, is that the way we share information among ourselves as American citizens has been radically transformed. The line between news and entertainment has almost dissolved, where ratings now have a big impact on what kinds of stories are covered and not stories.

I think it's harder for people than it should be. But as more and more of us become carbon neutral and change the patterns in our lives to be part of the solution instead of part of the problem, we are now beginning to see the changes in policy that are needed.

For me, the most serious problem is how America became so vulnerable to the assertion of blatant falsehoods that drive policy and are not corrected by the so-called immune system of democracy, a free press and a free democratic discourse.

Judge Roberts is a brilliant lawyer, a brilliant judge. He is a very careful judge, a thoughtful judge. I would agree with what the President said earlier. He is a decent man. I think everybody who knows him likes him.

We have arrived at a moment of decision. Our home - Earth - is in grave danger. What is at risk of being destroyed is not the planet itself, of course, but the conditions that have made it hospitable for human beings.

The choice to 'do nothing' in response to the mounting evidence is actually a choice to continue and even accelerate the reckless environmental destruction that is creating the catastrophe at hand.

Remember America, I gave you the Internet and I can take it away.
