It has been more than 50 days since the Deepwater Horizon oil rig exploded in the Gulf of Mexico killing 11 workers.
The rig burned and sank but BP is still struggling to plug the leak that is pumping millions of litres of oil into the ocean.
Birds, sea turtles, dolphins and other animals are washing up on shore and the leak is not expected to be stopped for months.
Residents of the Gulf coast depend on those waters and the marsh for their livelihood.
From shrimping, fishing and oyster beds to tourism, the people who live there have built their lives around this habitat for centuries.
The scale of the damage is unknown but many fear that this man-made disaster will destroy that way of life.
On Wednesday's Riz Khan show we talk to Noah Hall, the executive director of the Great Lakes Environmental Law Center, and Diane Wilson, author of An Unreasonable Woman: A True Story of Shrimpers, Politicos, Polluters, and the Fight for Seadrift, Texas.
