When Wal-Mart brings water down to the Katrina victims, it's not doing that to be nice; it's doing it to make larger profits and to increase the value of its shares. If its actions are not accomplishing those objectives, the shareholders can sue the executives, and sue them successfully, because it is illegal for them to act on behalf of any other reason than increasing the value of their shares. There is nothing wrong with that. That is the way that they were created and the way we want them to function to increase prosperity in the market.

You show me a polluter, I'll show you a subsidy. I'll show you a fat cat using political clout to escape the discipline of the free market and force the public to pay his production costs.

Those guys are doing the Koch Brothers bidding and are against all the evidence of the rational mind, saying global warming does not exit. They are contemptible human beings. I wish there were a law you could punish them with. I don’t think there is a law that you can punish those politicians under.

I think we as Americans know there's a much better alternative than the 17th century practice of burning rocks to power our economy.

The most patriotic thing you can do is to take care of the environment and try to live sustainably.

It is more important to be of service than successful.
