Two eco activists from Canada will join me on the Green Front. Lynn Palmer and Scot Kyle are both from Ontario where environmental issues center around preserving forests and fighting threats from extractive industries, primarily mining. Lynn - who has participated in UN conférences - and Scot - a Green Party candidate in Canada - weigh in on Canada's recent pullout from Kyoto Accords, Keystone controversy and the threat of climate change. Next, a chat with Ken Silber, a conservative Republican writer and blogger who is trying to move his party leaders in a greener direction, and advocating for a carbon tax.
