The Gulf of Mexico is losing sea grass beds at an alarming rate. According to a new aerial survey, Mobile Bay has lost nearly 14-hundred acres of sea grass beds in the last few years. And as Tanya Ott reports, that could affect your dinner plate.

Americans love shrimp. And shrimp love sea grass beds. But as Tanya Ott reports sea grass beds are dying at an alarming rate.

Each American eats on average four pounds of shrimp a year. But a new aerial survey of the Gulf of Mexico finds the place where shrimp, crab and a lot of different fish find their food is disappearing. Scientists say agricultural runoff and sediment from development are killing off sea grass beds. Dauphin Island Sea Lab scientist Ken Heck says part of the problem is PR. Sea grass beds just are’t as sexy as some other ecosystems.

“Many people know about coral reefs and they know about tropical rain forests. But sea grass habitats are a bit under-loved and under-appreciated.”

Sea grass decline isn’t just a problem in the Gulf of Mexico. Heck is part of team doing a global sea grass census. He says worldwide a third of sea grass beds have disappeared.
