The new Netflix series “Our Planet” documents the devastation wrought by humans on animals and their habitats. It’s heartbreaking. In fact, some scenes are so wrenching that Netflix last week tweeted a list of time stamps for scenes that “animal lovers may want to skip.”
One of those scenes is in the second episode (“Frozen World”). It shows Pacific walruses, one after another, tumbling off 250-foot-high cliffs to their deaths.
