"Is it really going to hurt if a few 1000 seals and sea lions are killed. I know it wouldn't hurt my feelings."

If a thousand sasquatches descended from the mountains and started seeking revenge on humans for exploiting "their" resource I'll bet you'd pat them on the back, damn humans keep stealing their fish...
