I'll give you that "Once Upon a Forest" is kind of an eco-toon. But I really don't think so. It's far more about the journey of the furlings; of them becoming adults. The poisonous gas is just a plot-device to make the trip necessary. And it was the result of an *accident*, not an intentional evil.
