. Coast watch. Marine resources; Oceanography; Coastal zone management; Coastal ecology. ea turtles have survived for more than 150 million years with little more than their shells to shield them. They have swum the oceans since the time of dinosaurs, outliving their reptilian cousins by centuries. But now, sea turtles seem headed for a similar fate. Of the seven species in the world, six are considered endangered or threatened with extinction. Five species—loggerhead, leatherback, green, Kemp's ridley and hawksbill—can be found in the Southeast. More than 99 percent of the nesting turtles in North Carolina are loggerheads. Some theories hold that the populations of these giant sea creatures are declining naturally. Extinction is a normal biological process, some researchers say. It's im- portant in the evolution of new species. But most scientists and environmentalists blame the turtle's demise on people. And now, they say the responsibility to halt the decline and to aid in the turtles' recovery is ours, too. "Sea turtles have been a great success through time, until about 100 years ago, " says Bill Brooks, naturalist for the Bald Head Island Nature Conservancy. Excessive exploitation began then. People around the world captured sea turtles and their eggs for food, fisheries and trade. By the 1960s, more than 75 percent of the population had been eliminated. Conservationists retaliated and the government took action. A ban was placed on turtle fishing, and in 1973, the Endangered Species Act made it illegal to Surviv take or disturb adult turtles and their eggs. Worldwide, treaties were passed for further protection. Still, sea turtle populations decline. Many countries ignore the international treaties that protect the turtles, says Marydele Donnelly, director of the Sea Turtle Rescue Fund of the Center for En- vironmental Education. From 1970 to 1986, 2 million hawksbill sea turtles were killed for their shells and sold in the Japanese market. Olive
