Why have the bioluminescent bays
of Puerto Rico gone dark?
The ecology of dinoflagellates
is a complex system with many factors:
Temperature, salinity, depth,
and, of course, absolute darkness.
It may be that light pollution
has driven the glowing algae away.
One way to kill a thing
is to love it too much, to shine
Your light on it and make it burn
or slink away into the shadow.
