Quote: "Ocean bulldozers" - enormous nets weighed down with rollers - scrape the ocean floor

I mentioned earlier that those rollers have the power to push aside twenty-five-ton boulders. They pulverize everything in their path, crushing deep coral, grinding boulders to rubble, wiping out populations of old fish and other creatures, which will take generations to recover, and leave behind a flat, lifeless moonscape of gravel and sand.
