John Kerry: “we can't do much about the past, but we can certainly do something about today and the future.”

People think this is now, you cannot reverse it, it is irreversible.

We are competing, but everybody has their own approach, which is one of the exciting things here.

What a shame for our country that that happened.

I have to admit to you, if anybody thinks it is radical to care about the protection of this planet for future generations, sign me up.
