On this water planet we often think of the land before the sea. 14% of Earth’s land is protected where as not even a percent of the world ocean is a marine reserve. Abundant large predators are signs of a stable ecosystem; animals at the top of food chains are most vulnerable (as well as those that mature and reproduce late in there lives). At one time there were Bluefin Tuna as large as 14 feet long and around 2,000 lbs! Callum Roberts, author of The Unnatural History of the Sea, says that we need to have at least 20 -40% of the ocean off-limits to fishing. Currently, the less abundant fish are caught by more complex fishing technology. We could be more blue.
