What we should be doing [in US] is accelerating every year our efforts to reduce our greenhouse gas emissions, have a cleaner energy future, have much more energy conservation. And this won't hurt anybody. This will create a new economy for America, if we've got the discipline to do it.

We are more connected than ever before, more able to spread our ideas and beliefs, our anger and fears.
