Stress kills turtles. Even if an animal survives, the damage has been done, and it's only a matter of time until it dies. In fact, we forced them to put in some humane standards back in the early 1970s. You don't condemn a whole activity by an isolated shipment. Dogs have disease, too.
Dogs run free.
There's a split in the environmental community. There are some people who believe in sustainable use. There are some that don't. I guess it depends how you define sustainable. Something was bothering me about all the turtle conservationists I talked to.
