Susan Shaw

Fabien Cousteau, a filmmaker, oceanographic explorer and grandson of Jacques Cousteau, and marine toxicologist Susan Shaw talk about the health of the oceans and conservation. Susan dove into the BP oil slick in May 2010 to assess the impact of oil and the chemical dispersants used to clean the spill, which had a devastating impact on marine life in the Gulf and human health.

It's been four days since BP put a cap on the Deepwater Horizon oil well and, with cautious optimism, people have begun talking about recovery. But just because the oil has stopped gushing doesn't mean the damage is done. In fact, say some scientists, more harm is soon to come.
