Can cloning stop extinction?

Malaysia is trying to think of ways to prevent the leatherback turtles from going extinct. Because of pollution, eggs are no longer fertile and turtles cannot produce offspring. Scientists have come up with a solution to save these animals by cloning them. However, turtles are reptiles and scientists never cloned reptiles before, only mammels. The project will cost about $9 million and there is a chance that it will fail. Should it be done?
