Which of the following best explains the environmental problems associated with trawling?

Trawling uses nets that can catch many kinds and sizes of marine life, including unintended species, so it is often criticized for being indiscriminate. It can also damage seafloor habitats, but it does not always destroy them; therefore, “all of the above” is not correct. The best choice is “Trawling gathers fish indiscriminately.”
