When Eric Mann first encountered environmentalists, he saw them as a bunch of “arrogant, racist airheads.” When Frances Beinecke first encountered environmentalists, she felt she’d found her cause. Now, both are tireless proponents of environmental sanity, but they work in very different ways. Mann is director of the L.A.-based Labor/Community Strategy Center, where he fights for environmental justice, immigrant and labor rights, and economic equity. Beinecke is president of Natural Resources Defense Council, one of the nation’s biggest green groups. We got the two of them talking about poverty, the environment, and building a stronger movement; find out what they had to say.
