What are the motives for establishing marine sanctuaries and reserves?
What will be an ideal response?
With the great majority of commercial species overfished or fished to the limit, marine reserves and sanctuaries give some of these species' populations a change to recover. These protected areas allow habitats of marine life to recover in biodiversity and productivity, and the proven success of reserves in many types of ocean environments is having a "spillover" effect as protected species spread outside reserves.
