Banks are increasingly viewed as a bane to a healthy economy. But done right, banks can play a key role in the shift to sustainability. Today, Sea Change presents three perspectives on futures for banking. Peter Blom, CEO of Triodos Bank in the Netherlands, proposes a shift in the mission of banks, from maximizing profit to maximizing sustainability. Doug Rushkoff, author of LIFE INC, discusses how a surplus of debt that banks needed to sell triggered the financial meltdown. And Lyle Estill describes the role a chapter in his book SMALL IS POSSIBLE played in a local currency in North Carolina, The Plenty, being carried by a local bank.
