Greenpeace and Canned Tuna Truth Squad : In Their Own Words
Marine reserves are highly protected areas that are off limits to all extractive and destructive uses, including fishing. They are the most powerful tool available for the conservation of ocean wildlife.
The creation of marine reserves cannot guarantee the survival of tuna, and could actually lead to further declines. Ocean acidification, warming oceans, sea level rise, unregulated fishing, dead zones from pollution and illegal fishing are all greater threats to the survival of tuna, and the creation of marine reserves wont address any of them. Furthermore, tuna are a highly migratory species, making the use of marine reserves to preserve their numbers a problematic exercise.
