This vid is very provocative and entertaining, but it is wrong in a number of places including linking the Prius to ecological damage around the Nickel factory. The Mail on Sunday ran this story earlier this year and had to retract it.
On the bigger picture - if only the big problem was too much green consumption. Global damage is being caused predominantly by non-green consumption (the lady's family would probably buy 7 non-hybrids instead).
Anyway, enjoy it, let it make you think, but don't take it as gospel!
