Polar bears would literally eat you alive if they got the chance. We need them as much as we need sabre-toothed tigers and velociraptors.
Wow, that's a really stupid point of view. Thanks for sharing. We need know-nothings who misunderstand biodiversity and how the ecology of this planet actually works about as much as we need velociraptors, I'd say.
I'm confused. In your last sentence you both imply that biodiversity is important and that having velociraptors back would be bad. But clearly, having velociraptors around would increase biodiversity. Make up your mind!
