It’s 1964, and J pod ancestor Moby Doll is harpooned and put on display at Vancouver’s waterfront. The crowds are delighted, until he dies.

J pod is an urban orca family, but have we made the very water they swim in uninhabitable? And why are other orca populations thriving along the same tainted coast line? From pollution to the blob, we ask, are major ocean changes a killer?
