Safe From Harm?


Across the globe, some 5,000 marine protected areas (MPAs) have been created. These preserves were established to safeguard the areas' wildlife and habitats—but results are mixed. Some MPAs are closed to all activities, but many are open for recreational use and others still allow commercial and sport fishing. Currently, less than 1 percent of the world's oceans are closed to fishing.
