Ocean conservation: Uncertain sanctuary.

The article discusses the insufficient environmental protection efforts of some countries in their designated and declared marine protected areas (MPAs). It says that studies reveal some MPAs like the Great Barrier Reef Marine Park in Australia have adequate protection to marine ecosystems but some MPAs only exist in paper and offer no real protection and have design flaws that protects the wrong habitats. Furthermore, these problems will grow as countries join forces to establish larger MPAs.
