So---why can't they bring up this fishing net? Or do they just leave it there permanently to snag marine life and kill things--including people now.
There are thousands (tens of thousand ?) fishing nets left on the ocean floor snagged on reefs, wrecks, and rocks underwater.
Identification alone is nearly impossible, recovery unreasonable (billions of dollars), and even if you tried, your never get all of the pieces, nor even all of the of the major parts up.
And, to what end?
