                                                   Is blue growth the beginning or 
                                                        end of a healthier ocean?

March 17th 2015

Across the globe, countries are increasingly looking seaward in search of new economic opportunities, including oil, gas, and mineral extraction from the sea floor, renewable energy development, and biotechnology.
The push to expand this so-called “blue economy" comes at a time when the ecological health of the oceans is seriously degraded. Last year, the Economist's World Ocean Summit concluded with a resounding consensus that more needs to be done to protect and restore the world's seas, especially the high seas. Will blue growth help or harm efforts to achieve a healthier ocean ecosystem?
The U.N. has proposed ambitious sustainable development goals relating to ocean health. They include reducing pollution from agriculture run-off, decreasing untreated sewage and solid waste, rebuilding depleted fish stocks, and protecting and restoring natural habitats.
A healthy ocean ecosystem is a public good—both locally and globally. Mangroves, corals, and salt marshes protect  coastal towns from storms. Oceans store carbon and produce oxygen that benefits us all. And areas of high biodiversity support global fisheries and are essential for resilient and productive oceans.
These natural benefits can remain intact if nations encourage—and even require—participants in the blue economy to reinvest the economic capital created from that economy in the natural capital of marine and coastal ecosystems; namely by restoring degraded habitats, protecting healthy ones, and financing blue economy “greening" efforts.
Channeling the new wealth of a growing blue economy into projects that will build a healthier ocean will require new financial tools. For instance, a global ocean trust fund, eco taxes, or user fees could be managed at the global level (say the U.N., World Bank, or the Global Environmental Facility) or even at a regional level, perhaps through existing regional seas organisations.
But for now the blue economy needs to aim higher than merely to do no harm. Converting blue economic capital into blue natural capital can raise all boats and produce a healthier, more sustainable blue economy.

                                                 SOUTHERN HUMPBACK WHALE

INTRODUCTION




    During the Australian winter, these ocean leviathans journey 3,100 miles north from their Antarctic feeding grounds to the warm tropical waters near Australia´s Whitsunday Islands. At the southern edge of the Great Barrier Reef, the 40-ton female humpbacks give birth to calves measuring 14 feet long and weighing over one ton. The Whitsundays´ sheltered bays keep the calves warm and safe from predators. During the next few months, the whales rest, sing, play and mate. The calves nurse, but the one thing the adult whales don´t do while in the tropical seas is eat. By winter´s end, adults are famished, and they head south. This life cycle is repeated throughout the Southern Hemisphere: one group migrates along the western coast of Australia, others to southern Africa and South America.

                                                                SIGHT UNSEEN



    Underneath the blue Australian ocean, film crews captured the elegant rituals of southern humpbacks as they swim, sing, nurse, and play. A mother humpback whale supported her young calf from underneath, so it could breathe easier near the surface. Calves drink 130 gallons of milk a day! While baby grows fat, the mother starves for five months, her blubber stores depleting daily. Unlike the cold Antarctic waters, the seas here don´t grow rich with krill that humpbacks filer through their baleen plates. But she provides her calf with rich milk that contains some of the highest fat content of any mammal´s milk – 45 percent.
                                                             UNIQUE BEHAVIOR

    Humpback males sing a unique melody, full of high-pitched chirps and whistles interspersed with deeper gurgles and moans. Each male repeats his song for hours, which likely plays a role in courtship. The song may change over time, with males singing a modified melody in consecutive years.
    Whale-watching tours take advantage of the humpback´s playful and curious nature. They often approach boats and put on quite a show. As whales journey south along the eastern coast of Australia, many stop in sheltered Platypus Bay around Fraser Island – a World Heritage Site – where they display the charismatic behaviors loved by whale-watchers. The crystal blue waters give a perfect window to watch the whales twist, roll and swim upside down, emerging to breathe, slap their tails or pectoral fins on the water´s surface. Breaching whales jump nearly all the way out of the water. “Spyhopping" means their head emerges, and they peer at the surroundings with their large eyes.

                                                        STATUS/CONSERVATION

    Commercial hunting in the 19th and 20th centuries decimated most whale species. Because they migrate close to shore and swim slowly, humpbacks became a popular whalers´ target, and were hunted down to a few hundred animals in the Southern Hemisphere. The International Whaling Commission (IWC) implemented a moratorium on harvesting all species starting in 1986, and in 1994, declared Antarctica´s Southern Ocean a whale sanctuary. Now numbering over 10,000 in the Southern Hemisphere, humpbacks have shown incredible resilience, but their numbers still remain a fraction of their historic abundance. Recovery of regional populations varies, and the World Conservation Union (IUCN) lists the humpback as vulnerable.
     Humpbacks also have two Northern Hemisphere populations that number around 11,500 in the North Atlantic and 6,000 in the North Pacific. Northern humpbacks are genetically differentiated from the Southern Hemisphere population, and have dark bellies, while the southern humpbacks have all-white bellies. They don´t interbreed, because while the southern populations are mating and calving in the warm tropical seas, northern populations are near the polar Arctic.

                                                                  OUTLOOK



     The International Whaling Commission (IWC) allows hunting by indigenous cultures but bans hunting of humpback whales. Japan has long engaged in IWC-sanctioned “scientific whaling" of minke and other whales, and plans to start hunting humpbacks in 2007. “We are all concerned about Japan´s plans to add this species to the scientific whaling quota", says Dr. Scott Baker, a renowned cetacean conservation biologist. Iceland also just started commercial whaling in 2006.

    Some Asian countries allow the sale of whale meat from incidental bycatch, and a whale´s value of $100,000 provides incentive for illegal harvest. Baker and colleagues used DNA to show that the whale meat being sold in South Korean shops did not match that reported to the IWC. Illegal harvest and sale of whale meat is occurring.

    Australia and New Zealand have petitioned the IWC to create a South Pacific Sanctuary adjoining the Southern Ocean Sanctuary where whaling would be illegal. Thus far, it has not been approved by IWC.

                                                 SOUTHERN HUMPBACK WHALE

INTRODUCTION




    During the Australian winter, these ocean leviathans journey 3,100 miles north from their Antarctic feeding grounds to the warm tropical waters near Australia´s Whitsunday Islands. At the southern edge of the Great Barrier Reef, the 40-ton female humpbacks give birth to calves measuring 14 feet long and weighing over one ton. The Whitsundays´ sheltered bays keep the calves warm and safe from predators. During the next few months, the whales rest, sing, play and mate. The calves nurse, but the one thing the adult whales don´t do while in the tropical seas is eat. By winter´s end, adults are famished, and they head south. This life cycle is repeated throughout the Southern Hemisphere: one group migrates along the western coast of Australia, others to southern Africa and South America.

                                                                SIGHT UNSEEN



    Underneath the blue Australian ocean, film crews captured the elegant rituals of southern humpbacks as they swim, sing, nurse, and play. A mother humpback whale supported her young calf from underneath, so it could breathe easier near the surface. Calves drink 130 gallons of milk a day! While baby grows fat, the mother starves for five months, her blubber stores depleting daily. Unlike the cold Antarctic waters, the seas here don´t grow rich with krill that humpbacks filer through their baleen plates. But she provides her calf with rich milk that contains some of the highest fat content of any mammal´s milk – 45 percent.
                                                             UNIQUE BEHAVIOR

    Humpback males sing a unique melody, full of high-pitched chirps and whistles interspersed with deeper gurgles and moans. Each male repeats his song for hours, which likely plays a role in courtship. The song may change over time, with males singing a modified melody in consecutive years.
    Whale-watching tours take advantage of the humpback´s playful and curious nature. They often approach boats and put on quite a show. As whales journey south along the eastern coast of Australia, many stop in sheltered Platypus Bay around Fraser Island – a World Heritage Site – where they display the charismatic behaviors loved by whale-watchers. The crystal blue waters give a perfect window to watch the whales twist, roll and swim upside down, emerging to breathe, slap their tails or pectoral fins on the water´s surface. Breaching whales jump nearly all the way out of the water. “Spyhopping" means their head emerges, and they peer at the surroundings with their large eyes.

                                                        STATUS/CONSERVATION

    Commercial hunting in the 19th and 20th centuries decimated most whale species. Because they migrate close to shore and swim slowly, humpbacks became a popular whalers´ target, and were hunted down to a few hundred animals in the Southern Hemisphere. The International Whaling Commission (IWC) implemented a moratorium on harvesting all species starting in 1986, and in 1994, declared Antarctica´s Southern Ocean a whale sanctuary. Now numbering over 10,000 in the Southern Hemisphere, humpbacks have shown incredible resilience, but their numbers still remain a fraction of their historic abundance. Recovery of regional populations varies, and the World Conservation Union (IUCN) lists the humpback as vulnerable.
     Humpbacks also have two Northern Hemisphere populations that number around 11,500 in the North Atlantic and 6,000 in the North Pacific. Northern humpbacks are genetically differentiated from the Southern Hemisphere population, and have dark bellies, while the southern humpbacks have all-white bellies. They don´t interbreed, because while the southern populations are mating and calving in the warm tropical seas, northern populations are near the polar Arctic.
