Fifty Percent Of The World's Population Lives In Cities. In A Couple Of Decades, 70 Percent Of The World's Population Will Be Living In Cities. Cities Are Where The Problem Is. Cities Are Where The Solution Is, Where Creativity Exists To Address The Challenges And Where They Have Most Impact. This Is Why, In 2005, The C40 Was Founded, An Organization Of Cities That Address Climate Change. It Started With 18 Cities; Now It's 91. Cities Simply Are The Key To Saving The Planet.

And I Think The More Money You Put In People's Hands, The More They Will Spend. And If They Don't Spend It, They Invest It. And Investing It Is Another Way Of Creating Jobs. It Puts Money Into Mutual Funds Or Other Kinds Of Banks That Can Go Out And Make Loans, And We Need To Do That.

Cities With Clean Air Gain An Economic Advantage, Because Where People Want To Live And Work, Businesses Want To Invest.
