Bulldozing the Bottom of the Sea

It is a wonderfully clear expression, used by a U. S. biologist about the impact of bottom trawling. "Imagine using a bulldozer to catch songbirds for food — that's what it's like," marine biologist Sylvia Earle says. "After a trawler has gone by, it looks like a superhighway, it's just flat. Nobody's home. A few fish may swim in and out but the residents, those that occupy the substrate, they're just smothered, they're crushed. It's like paving them over."
