Lecture video description from TED: Why do we turn to nonprofits, NGOs and governments to solve society’s biggest problems? Michael Porter admits he’s biased, as a business school professor, but he wants you to hear his case for letting business try to solve massive problems like climate change and access to water. Why? Because when business solves a problem, it makes a profit — which lets that solution grow.

Michael E. Porter wrote the books on modern competitive strategy for business. Now he is thinking deeply about the intersection between society and corporate interests.
