2 hundred years in the past, on November 17, Connecticut ship captain Nathaniel Palmer noticed the Antarctic continent, considered one of three events to take action in 1820. Not like explorers Edward Bransfield and Fabian von Bellingshausen, Palmer was a sealer who rapidly noticed financial alternative within the wealthy sealing grounds on the Antarctic Peninsula.
Within the two centuries since, Antarctica has seen a spread of economic, scientific and diplomatic developments. Whereas some nations tried to assert territory on the continent within the first half of the twentieth century, at present the area is ruled by means of the worldwide Antarctic Treaty System.
Though the treaty claims to control Antarctica within the pursuits of all “mankind,” some nations have gained larger advantages from the area than others. Whereas mining is at the moment banned beneath the Antarctic Treaty and the times of sealing and whaling are over, Antarctica’s marine dwelling assets are nonetheless being exploited to this present day.
Fur and blubber
Palmer was adopted by a rush of different sealing ships, principally from the USA and Britain, that methodically killed fur seals alongside Antarctic seashores, swiftly taking populations to the brink of extinction. Seal fur was used for clothes within the 18th and nineteenth centuries in lots of elements of the world and was an essential a part of U.S. and European commerce with China within the nineteenth century.
Fur sealing had an actual boom-and-bust high quality. As soon as a area was picked over, the sealers would transfer to extra fruitful grounds. Earlier than 1833, at the very least 7 million fur seals have been killed within the Antarctic and sub-Antarctic. As early as 1829, British naturalist James Eights lamented the lack of the fur seal on the Antarctic peninsula: “This lovely little animal was as soon as most quite a few right here.”

Elephant seals have been additionally hunted, however for his or her blubber, which could possibly be transformed into oil. It was not troublesome for hunters to drive them to the seashores, lance them by means of the guts (or, later, shoot them within the cranium), drain their blood and take away their blubber. “We left the lifeless issues, uncooked and meaty, mendacity on the seashore,” in accordance with one sealer. The birds would choose the skeletons clear inside days.
Sealing quickly declined within the Nineteen Sixties, owing to a mixture of evolving cultural sentiments and altering availability of different supplies, comparable to plastics, that could possibly be made into heat artificial clothes and petroleum-based lubricants.
The published of footage exhibiting Canadian sealing within the early Nineteen Sixties scandalized North American and European residents and prompted a fast shift in attitudes towards sealing. The Conference for the Conservation of Antarctic Seals was signed in 1972, regulating the large-scale slaughter of seals for all nations within the area. At the moment, the inhabitants of fur seals has rebounded, with a colony of over 5 million on South Georgia alone, although numbers have declined since 2000. Elephant seals, too, have largely rebounded, with an estimated secure inhabitants of 650,000 because the mid-Nineteen Nineties.
The whaling grounds off Antarctica have been so wealthy they drew fleets from many countries. First got here Norwegian and British corporations, later to be joined by others from Germany, Russia, the Netherlands and Japan. Whaling had occurred within the Southern Ocean within the nineteenth century, but it surely wasn’t till the primary half of the twentieth century that whales have been hunted to close extinction there.
Within the nineteenth century, whale oil was used primarily for lamp gasoline. However after 1910, new makes use of have been discovered for the oil, together with as industrial lubricants and edible fat.
Whaling turned extraordinarily profitable for a small group of corporations, together with Unilever, whose early fortunes have been constructed from margarine made with whale oil.

At first, whales killed at sea needed to be dropped at a shore station to be processed. In 1925, an observer wrote, “What an appalling stench it’s…The water wherein the whales float, and on which we too are using, is blood purple.” From the late Twenties on, these shore stations have been changed by pelagic whaling stations, the place whales have been processed extra effectively on manufacturing facility ships at sea.
In 1946, some worldwide efforts have been made to guard whales. The purpose of the Worldwide Whaling Fee created that 12 months was “to supply for the right conservation of whale shares and thus make doable the orderly growth of the whaling business.”
However, once more within the Nineteen Sixties, public attitudes towards whales, like seals, started to alter when environmentalists revealed they have been extremely smart, sociable creatures that sang within the ocean depths. Most nations ceased whale searching within the Antarctic by the top of the Nineteen Sixties – due to this consciousness and likewise as a result of there have been cheap alternate options to whale merchandise.
Antarctica’s wealthy marine life continues to be exploited at present. Krill and toothfish started to be fished within the Nineteen Seventies.
Krill, a small shrimp-like crustacean, is utilized in dietary dietary supplements and pet meals. Norway, China, South Korea and Chile are its greatest harvesters. Toothfish, which has been marketed as Chilean sea bass, is on menus worldwide.

Since 1982, the Fee for the Conservation of Antarctic Marine Dwelling Sources has managed these fisheries with the overriding purpose of sustaining the entire ecosystem. Whales, seals, birds and different fish depend on krill, making them important to the Antarctic marine ecosystem. Whereas krill and toothfish are at the moment each plentiful within the Antarctic, it’s unclear how a lot the discount of sea ice and the altering migration patterns of predators who feed on these species are affecting their populations.
Traditionally and at the moment, solely a small variety of individuals have profited from Antarctica’s dwelling assets, on the nice expense of animal populations. Even when sustainable harvesting is feasible now, local weather change is quickly undermining Antarctic’s ecological stability. Whereas main environmental campaigns attempt to increase consciousness of Antarctica’s fragility, most shoppers of its merchandise doubtless don’t even know their provenance. Whale and seal populations proceed to recuperate from previous overexploitation, however the future impacts of present fishing practices and local weather change are unsure.
