Study Says Trawling for Fish May Unleash as Much Carbon as Air Travel

The report also found that strategically conserving some marine areas would not only safeguard imperiled species but sequester vast amounts planet-warming carbon dioxide, too.

For the first time, scientists have calculated how much planet-warming carbon dioxide is released into the ocean by bottom trawling, the practice of dragging enormous nets along the ocean floor to catch shrimp, whiting, cod and other fish. The answer: As much as global aviation releases into the air.

While preliminary, that was one of the most surprising findings of a groundbreaking new study published on Wednesday in the journal Nature
