The fishing industry throughout the Pacific has been harmed by many factors, the largest of which is over-fishing by huge fishing fleets from Japan, South Korea, Taiwan, and the United States. These nations have often ignored restrictions placed on their
activities. Many nations also use fishing methods that kill large numbers of other animals. Drift nets, for example, can measure over
a mile long and catch not just tuna but marine mammals such as dolphins. The fragile coral reefs in the South Pacific are another
greatly threatened marine resource. Tourists and tour guides often approach the reefs too closely, and pollutants such as fertilizer
chemicals create runoff that damages the reefs.
