Brian Darling, Human Events & Erikka Knuti, Democratic Strategist & Heather Cirmo, Conservative Strategist join Thom.

For tonight's "Conversations with Great Minds" - Thom is joined by author, environmentalist, and activist Bill Mckibben. In 1988, he wrote "The End of Nature" - the heir to Rachel Carson's "Silent Spring" - and since then has gone on to write more than a dozen noteable books about the environment and our human impact on it. He is the co-founder and Chairman of the Board of the grassroots climate campaign 350.org, which has coordinated 15000 rallies in 189 countries since 2009. In 2010, the Boston Globe called him "the nation's leading environmentalist" and Time magazine described him as "the world's best green journalist." And recently he was elected a fellow of the American Academy of Arts and Sciences. His latest book - "Earth: Making a Life on a Tough New Planet" - is a guide to living on our fundamentally altered planet.

Meet Eric Schneiderman - he's our best shot at making sure banksters pay for the crimes they committed on Wall Street - crimes that have led to millions of Americans losing their jobs, homes, and livelihoods. Crimes that SO FAR - have gone unpunished. Earlier this week - Schneiderman - who is New York's Attorney General - was kicked off a panel of state officials from around the country who are working with the Obama administration to come up with a one-time settlement for banksters to pay up for their crimes. Once that settlement gets paid - then everything else gets swept under the rug - no further lawsuits - no jail time - no nothing - the crime of the century gets forgiven. The number being floated around is a $25 billion fine - to be shared by ALL the big banks on Wall Street. In other words - pocket change for banksters. But Schneiderman doesn't like the idea - that's why he was kicked off. As Attorney General of New York - and thus the lead police chief of Wall Street - Schneiderman has the power to bring whatever investigations he wants against banksters - and he plans to do just that. He's already launched investigations into Wall Street giants like Goldman Sachs, Morgan Stanley, and Bank of America. And he wants Wall Street held FULLY accountable for the damage they caused - and not just a slap on the hand. So why is the Obama Administration NOT on Schneiderman's side? And how much longer will the American people put up the banksters skirting the law?

John Deans, Greenpeace, joins Thom Hartmann. Are the Koch brothers playing into the hands of terrorists? According to a new Greenpeace report - the Koch's have spent huge sums of money lobbying against legislation that requires greater security at chemical plants prone to terrorist attacks. Currently - thousands of chemical facilities across America are putting more than 100 million people at risk if terrorists were to target those facilities. Koch industries and its subsidiaries run 57 of those chemical plants putting 4.4 million Americans in harm's way. And while countless environmental, labor, and health organizations are pushing for legislation that requires companies to beef up their security - the Koch's are quietly trying to defeat those efforts. That's because they know more money spent on security means less money in profits. So how are they getting away with this? And shouldn't profits come second to saving American lives?
