Actually, I would think looking at the amount of lead weight from
abandoned fishing lines would have a more significant potential impact
than diver's weights. For example, one of our divers recently took part
in a lead fishing weight recovery effort with 10 other divers. With 11
people doing two dives each, they recovered over 220 pounds of lead
fishing weights at one dive site on Oahu.
