The ‘high seas’ are areas of ocean open to use by all nations. This makes them vulnerable to exploitation. Marine protected areas (MPAs) are parts of the ocean in which most commercial activity (e.g. trawler fishing) is prohibited, in order to prevent over-exploitation. Most of these MPAs are not in the high seas, but in areas near coasts, controlled by individual nation states. The map shows the existing high-seas MPAs and some of the areas which are candidates for new ones (described in the text boxes).
