Now, if coral reefs are that important, OK.

"Artificial reefs" are a fantasy. Dumping big hunks of garbage on the sea
bed does not work. It's just a phony political excuse to make throwing
something away sound charitable, like giving your busted junk to Goodwill.

In Florida they are paying many times the original "savings" picking up
tires that were dumped offshore to supposedly be an "artificial reef", but
wound up just being garbage. I remember how holy this was all supposed to
be during the "ecology" craze of the 1970s.
