Trawling destroys the natural seafloor habitat by essentially rototilling the seabed. All of the bottom-dwelling plants and animals are affected, if not outright destroyed by tearing up root systems or animal burrows.

How are longlines threats to sharks?

For instance, long-line fishers leave lines drifting in the ocean for hours, sometimes days, then come back to collect the catch and throw away the dead animals they can’t sell. Researchers believe such practices have contributed to a 60 percent decline in shark numbers in Costa Rican waters over the last decade.
