FORT MYERS, Fla. - The grandson of legendary ocean explorer Jaques Cousteau says he sees the environmental impact of the gulf oil spill lasting for a long time. Phillipe Cousteau is spending his days in the gulf coast documenting the spill for his show "Oceans Blue" on Planet Green.

Cousteau says there is evidence the oil is making it's way into the food chain. He says, "it's been found in the tissue of crab larvae... which is a worrisome sign it will be with us for some time." Cousteau also says on his scuba diving trips in the gulf he's seen underwater blobs of oil. He calls them "toxic" and says it is still "negatively affecting the fish eggs, larvae, mature fish and sea turtles that swim out there."

The episodes of Cousteau's work will be seen later on Planet Green. Right now's he's hosting the channel's month long series of water themed prorgamming called "Blue August." To learn more about Cousteau's work and this months specials, go to
