Naomi Klein environmental video.

Naomi Klein spoke to a packed house in Bellas Artes last night, to present her latest book, on the topic of climate change, This changes everything.
Here's an interesting, if challenging, video she's made on climate change which I hope you will enjoy. Most of the participants speak slowly and clearly. 

Some terms you may not be familiar with are:

Tar sands = sand from which Canada is extracting oil.
First nation = Native canadian indians.
