Don't be fooled by the title. Dr Guy McPherson is no climate change sceptic, or anything similar. I don't really understand why he chose this title, but it seems he prefers the term 'durability'.
In this hard-hitting lecture you will hear a lot of important information and ideas. Mcpherson's remedy against the impending doom is to resort to permaculture.
If you can find just under an hour and a half to hear what he says, I think you will agree it's worth listening to, and that you'll hope he's wrong.
