"The steep decline of the Pacific Ocean leatherback turtle has gone so far the species could be extinct within no more than a decade, conservationists fear. A report by the US group Conservation International says leatherback numbers there have fallen by 97% in 22 years. Five of the six other species of sea turtle are also at risk of extinction, though not necessarily as acutely. Threats include fishing practices and the poaching of the turtles' eggs, but scientists say they can still be saved.
