Tim Jackson : An economic reality check

Tim Jackson at TEDGlobal 2010
An economic reality check  (transcript)
Summary
I think that the speaker is an economist after all.
People must think that it's time to protect our Earth from climate change, even if economic GDP numbers are falling, however, his opinion seems to be different from that. 1)
I think that the example he shows in the talk that the system of a company works by drawing revenues from sponsored links is not right.
Sponsors have to create more products to give for advertisement. Even if allocating revenues to a rainforest protection,  the number of releasing carbon is not reducing.
GDP fell but a country's more beautiful and our lives are better is not wrong.
The world has to redefine a meaningful sense of prosperity that the speaker tells us will be right.
We have to check correctly what to do for our economy.
