Vegetarian, Vegan and Animal Rights

I hate the idea of killing these mighty animals. But these are among the most dangerous and likely destructive beast which you could ever image. They should be killed outright or tranquilized and brought to zoos (if that is possible). The biodiversity will take a big hit with these aquatic monsters taking out large swaths of wetlands. Sadly it needs to be done now or allow them to become a monumental catastrophe in the future.
