The world largest conference and expo dedicated to green building, GreenBuild 2011 started with an opening plenary at Air Canada Centre in Toronto, Canada. Some of the guest speaker included, NY Times reporter and Pulitzer Prize-winner, Thomas Friedman, who spoke about the necessity of green revolution. Friedman recalls the year of 1979 as the year on path of consumption and the 2008 Economic crisis as the wake-up call of the downward spiral we the world have created. Ending with a call to action, Friedman said, "The challenge we have today is that we must become the regeneration."
