Over 125 people attended Professor Jeffrey Sachs' presentation. Despite a rainy start to the day, people waited patiently to check in and hear about the Future of Global Energy and Sustainable Development. The Harvard Club and the US Business Council on Sustainable Development also supported the event. Afterwards, Dr. Sachs stayed, signing books and answering questions. Appreciation certificates from the club, the city and Harris County were presented. Many pictures, many good memories were made.
