In environments where corporations become too interventionist and capture regulation themselves, the government must be able to battle back so that the people have a chance.

I think it's fantastically narcissistic to believe that in the entire universe, with all of the planetary systems that we've already discovered and the countless others that are out there, that we are the only forms of life. Now, the real question is not are there other forms of life out there, but are there other intelligent forms of life out there right now.

We live in a fantastically wealthy country. We don't have to worry about food. We don't have to worry about clothing. We don't have to worry about our safety. It's very easy for me to be an environmentalist. It's very easy for me to care about making sure that we protect the forests and the whales, and all that stuff.
