Watched it today. The last bird singing for a mate brought a tear to my eye. The whale shark being cut up did too. A few years ago I got to snorkel with a whale shark in Mexico. It's an amazing experience I will never forget. In little Cayman I got to tour a research facility where one of the projects they're working on is reef restoration. They monitor the water parameters to see what could cause bleaching events. Years ago their stag horn coral population was nearly wiped out so they're propagating new colonies to transplant out into the reef. I would love to take part in a project like that some day.
