Summary: <p>Jefferson Exchange — February 27, 2013, HOUR 2</p><p><b> <span class="headlinetext">Life on the Brink</span> </b><br><br> There is little question that the human impacts on the Earth would be less if there were fewer humans living on the planet. But bringing up population in an environmental context can be hazardous for the person discussing it. Several authors join up for just such a discussion in <a href="http://www.ugapress.org/index.php/books/life_on_the_brink/" target="_blank"><strong>"Life on the Brink: Environmentalists Confront Overpopulation,"</strong></a> a series of essays on the subject. Editor Philip Cafaro and essayist Charmayne Palomba will join us. </p>
