Topic you just read about. Unfortunately, each of the strategies described in the reading has a weakness. First, if we protect turtle eggs with a wire fence, the small turtles that hatch from these eggs may experience problems later in life. Remember, sea turtles need a highly developed magnetic sense to navigate in the sea. They use this sense to locate critical feeding and mating spots as well as to return to shore to lay their eggs. But if we build wire fences around the eggs, the metal of these wire fences distort the magnetic field in that area. Because of this distortion, the magnetic sense of the young turtles might not develop properly. Without a well developed magnetic sense, these turtles may have trouble surviving and reproducing later. Second, it's true that sea turtles are threatened by plastic bags and we should avoid adding more to the world's oceans. The problem is there are already billions if not trillions of plastic bags in the ocean. And these bags may take hundreds of years to decompose. And even as these bags slowly break up into smaller pieces, they remain harmful to sea turtles that swallow them. So even if we stop using plastic bags immediately, it won't solve the problem sea turtles are currently facing. Finally, the problem with turtle excluder is that fishers are very reluctant to use them. That's because excluders often reduce the amount of fish the fishers catch in their nets. That reduces the fishers’ income. Even if there is a law to use turtle excluders, fishers can easily avoid it. They can remove the excluder once they are at sea and then put it back when they return to port. So it looks like they used it the whole time even though they didn't. Since it's difficult to enforce the use of turtle excluders, their benefits would probably be fairly limited.
