Author Zac Unger dragged his family to northern Canada in order to write a book about a vanishing species. He wanted to write the quintessential requiem about the magnificent polar bear dying off.

“In 1973, there was a global hunting ban. So once hunting was dramatically reduced, the population exploded,” he explained on NPR.
