When an animal as big as a whale dies, its body becomes a whole new ecosystem. One whale carcass can support other forms of life for 50-to-75 years—basically as long as the whale itself lived.
This gorgeous video (I am not kidding. You will not need a unicorn chaser.) illustrates how that cycle works, using paper cutouts and simple puppetry. It's mesmerizing and enlightening.
