There would be a cost for dumping carbon into our atmosphere and a cap on total emissions. The government must make a clear and firm decision - terminating the idea in our society it is free to pump infinite amounts of carbon into the air. Once that happens, private capital will flow even more aggressively into developing and deploying the alternative, less-polluting technologies.

I think there's going to be a tug of war in this country over who are the real patriots because at a time of national crisis, economic collapse and calamity, ecological peril and social dislocation, the American people deserve to be a partner to the American government.

People in red states and blue states can agree that if we can fight pollution and poverty at the same time, letting people work their way out of poverty without undermining community health, we have a moral obligation to do so.

We have to accept that some very toxic stuff was marbled into the Trump phenomenon.

Environmental justice is the movement to ensure that no community suffers disproportionate environmental burdens or goes without enjoying fair environmental benefits.

The Trump phenomenon has a lot of really good stuff in it, the anti-elitism, the concern for America's economy in the Rust Belt, the desire to see better days for the country. That's all great stuff. Some of that stuff is Bernie Sanders stuff. The problem is that it's marbled through with xenophobia and misogyny and bigotry.

People in red states and blue states can agree that clean air is better than dirty air; therefore we should use clean energy where we can.
