Inuit and others across northern Canada have taken to social media to post #sealfies, or photos of themselves wearing, eating or hunting seals. It began as a protest against Ellen Degeneres' decision to donate money from her Oscar #selfie to an organization that opposes the Canadian seal hunt. But the trend has emerged as a social phenomenon in itself-a mass collection of photographs that show how important the seal hunt is to Canadian Inuit and others.
