Re: The world has plenty of plastic
Lost fishing nets are awful, especially the monofilament ones. In my younger days, I used to go wreck diving off the UK coast, mainly in the North Sea. Some of these wrecks had clumps of tangled netting, and the trapped, dead fish and crabs therein thus attracted further victims. There's no safe way for divers to remove this stuff in the low-viz, dark and tidal conditions, and monofilamnet is nearly invisible underwater, and practically impossble to cut.
I've also dived from chartered fishing boats, where fishermen would routinely discard cut ends of polyprop rope overboard with never a backward glance. This was a quarter of a century ago, so perhaps attitudes have changed.
