On Tuesday, February 13, the NY Salon will host a discussion, discourse, dialogue, and—okay, I'll say it—a debate called The Human Footprint—Has Civilization Gone Too Far? DISCOVER's fearless leader, Corey Powell, will take part in the debate, and judging by his position paper, he should have some good things to say. The event will be webcast from NY Salon's Web site.

As for the other participants, they include Ronald Bailey, the science correspondent for Reason, an outspoken and intelligent libertarian magazine. If you think Corey is fearless, check out Reason, and Bailey in particular—his views on environmentalism probably don't line up exactly with most DISCOVER readers (basically: it's a load of bull), but he makes some interesting, iconoclastic arguments.
