What is the Most Secluded Place in the World?

Seclusion can be found while hiking in the Dolomites in Italy or by rowing in Sweden, but civilization is always only a few kilometers away. But what are the really isolated, inaccessible, and so remote places that hardly anyone has ever seen? This remains a question for scientists. Geography has a term for particularly remote places: poles of inaccessibility. According to the University of California's Department of Geography in Santa Barbara, “The pole of inaccessibility is the most challenging to reach owing to its remoteness from geographical features that could provide access.”

The poles of inaccessibility are usually continental or oceanic. The continental poles of inaccessibility are located on the farthest land from coasts. For example, the Eurasian pole of inaccessibility is located in the northwest desert of China, the German news agency reported.

On the other hand, the oceanic pole of inaccessibility is the place located in the ocean or the farthest point from any land. This pole is located in the South Pacific and is known as Point Nemo. It is about 2,700 kilometers from the nearest land, the Pitcairn Islands.

The most isolated island in the world is the uninhabited Bouvet Island, in the South Atlantic and makes part of Norway since 1930. But the island has little to offer to those who dream of seclusion due to its harsh weather conditions. It is mostly home to algae and fungi that only grow in areas where the earth does not freeze, along with albatrosses, penguins and other cold-resistant birds.

The question is: Are these remote places really untouched? Reinhold Leinfelder, a geophysicist at the Free University in Berlin, says humans have changed the earth and left their mark everywhere. Even at Point Nemo, the remnants of a small-scale civilization can be found, for example.

Killer whales have been caught on video breaking off pieces of seaweed to rub and groom each other, scientists announced Monday, in what they said is the first evidence of marine mammals making their own tools.

Humans are far from being the only member of the animal kingdom that has mastered using tools. Chimpanzees fashion sticks to fish for termites, crows create hooked twigs to catch grubs and elephants swat flies with branches.

Tool-use in the world's difficult-to-study oceans is rarer, however sea otters are known to smash open shellfish with rocks, while octopuses can make mobile homes out of coconut shells.

A study published in the journal Current Biology describes a new example of tool use by a critically endangered population of orcas., AFP reported.

Scientists have been monitoring the southern resident killer whales in the Salish Sea, between Canada's British Columbia and the US state of Washington, for more than 50 years.

Rachel John, a Masters student at Exeter University in the UK, told a press conference that she first noticed "something kind of weird" going on while watching drone camera footage last year.

The researchers went back over old footage and were surprised to find this behavior is quite common, documenting 30 examples over eight days.

One whale would use its teeth to break off a piece of bull kelp, which is strong but flexible like a garden hose.

It would then put the kelp between its body and the body of another whale, and they would rub it between them for several minutes.

The pair forms an "S" shape to keep the seaweed positioned between their bodies as they roll around.

Whales are already known to frolic through seaweed in a practice called "kelping".

They are thought to do this partly for fun, partly to use the seaweed to scrub their bodies to remove dead skin.

The international team of researchers called the new behavior "allokelping," which means kelping with another whale.

They found that killer whales with more dead skin were more likely to engage in the activity, cautioning that it was a small sample size.

Whales also tended to pair up with family members or others of a similar age, suggesting the activity has a social element.

The scientists said it was the first known example of a marine mammal manufacturing a tool.

Janet Mann, a biologist at Georgetown University not involved in the study, praised the research but said it "went a bit too far" in some of its claims.

Bottlenose dolphins that use marine sponges to trawl for prey could also be considered to be manufacturing tools, she told AFP.

And it could be argued that other whales known to use nets of bubbles or plumes of mud to hunt represent tool-use benefitting multiple individuals, another first claimed in the paper, Mann said.

Michael Weiss, research director at the Center for Whale Research and the study's lead author, said it appeared to be just the latest example of socially learned behavior among animals that could be considered "culture".

But the number of southern resident killer whales has dwindled to just 73, meaning we could soon lose this unique cultural tradition, he warned.

"If they disappear, we're never getting any of that back," he said.

The whales mainly eat Chinook salmon, whose numbers have plummeted due to overfishing, climate change, habitat destruction and other forms of human interference.

The orcas and salmon are not alone -- undersea kelp forests have also been devastated as ocean temperatures rise.

Unless something changes, the outlook for southern resident killer whales is "very bleak," Weiss warned.
