There has to be - you know, this is like what I think Americans really have trouble with, an economy that's working for the privileged few, and there those privileged few are getting special favors from the political elite.

I was recruited to sort of be the doc to advocate for communities that were struggling with polluting incinerators, polluting coal plants, toxic waste sites, etc.

And "all the above" [what President Barack Obama calls his policy of promoting all forms of domestic energy], compared to "drill, baby, drill," if you actually look at the track record, we've massively escalated the emissions of methane and carbon dioxide.

My struggles have been around protecting our air quality, protecting people from mercury in fish. I was very involved in the effort to get the FDA to recognize that mercury in fish is a real health issue and the FDA, you know, needed to be on that. But they were very tight with the fishing industry and did not want the public to be aware in the same way that they later didn't want the public to be aware of the problems with Vioxx, and they sat on the studies for many years and allowed 140,000 people to develop heart disease.

I think, it was like 30 million dollars the Libertarians talk about that it cost them to get on the ballot. We don't have 30 million dollars. We're a people powered campaign.
