Just watched it - pretty good info, and a disturbing trend. At the very least, it's inspired me to read more about it. It's always difficult to wade into this because of the political aspect, but it's worth trying to understand.
The part about the almost-bleached corals fluorescing was pretty interesting. Is it that they start making new fluorescing pigments when near death, or do existing pigments show up when the normal pigments go away (like trees in the fall)? I'm guessing the latter.
GOOD news:
