Many commercial fishing vessels practice bottom-trawling in order to catch sea animals who live near, on, or under the sea floor, such as flounder, cod, grouper, shrimp, and scallops. Scientists say that the destruction caused by bottom-trawling is similar to that caused by clear-cutting old forests, only on a far greater scale. For example, the area of seabed trawled each year is roughly the size of the 48 contiguous states: 150 times greater than the area of forest cut! Elliot Norse, president of the Marine Conservation Biology Institute, says, “Scientists find that bottom-trawling is the largest disturbance to the world’s sea floor and possibly the largest human-caused disturbance to the biosphere.”
