Is Antarctica really some kind of entrance? Why is Antarctica off limit?

Actually, not necessarily, because the South Pole itself is at the pole of the earth, and it should be relatively cold.

No, Antarctica is Antarctic, it is not the entrance to some mysterious place, the climate of Antarctica is cold and naturally sparsely populated, and there is basically nothing else except ice. We are curious about things that we don't have a clear understanding of, and the cold exploration of Antarctica also makes everyone curious about it.

I don't think Antarctica is some kind of entrance, maybe everyone thinks that Antarctica is very mysterious to think so, but in fact, Antarctica is just a special terrain.

Because to protect the environment.

The increasing number of tourists visiting Antarctica will jeopardize the fragile environment of the region. Environmental protection is the number one priority for Antarctic tourism. The Antarctic ecosystem is so fragile that even a single alien seed can devastate Antarctica and threaten species patterns.

Developing safe and environmentally responsible Antarctic tourism has become a consensus for human development.

Antarctic tourism has been managed under the Antarctic Treaty framework and has been a key topic of the Antarctic Treaty Consultative Meeting. In addition, IAATO has developed and implemented environmental standards for the Antarctic tourism industry in accordance with the environmental requirements of the Antarctic Treaty system, and regularly provides reports on Antarctic tourism to the Antarctic Treaty Consultative Meeting.

At the beginning of the 19th century, the Antarctic continent was discovered. But because of the cold climate of Antarctica, there are no permanent inhabitants, and there are no immigrants from other places, so there are no settlers and no ** or state is established.

By the mid-20th century, the United Kingdom, France, Germany, Australia, New Zealand and other countries put forward territorial claims to the Antarctic continent, and since then the United States, Chile, Argentina and other countries have also put forward territorial claims to the Antarctic continent.

On December 1, 1959, representatives of 13 countries, including Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the United Kingdom, the United States, and the Soviet Union, signed the Antarctic Treaty in Washington.

The treaty stipulates that Antarctica shall be used only for peaceful purposes, guarantees freedom of scientific exploration in the Antarctic region, promotes international cooperation in scientific exploration, prohibits all activities of a military nature and the nuclear and processing of radioactive materials in the Antarctic region, freezes claims to territorial ownership, and promotes international cooperation in science.

The Antarctic continent is almost entirely covered by ice and snow, and there are many tall ice shelves, ice barriers and icebergs on the surrounding sea, and only 2 of the land is not covered by ice and snow all year round, which is known as the "oasis" of the Antarctic ice sheet and is the main habitat of Antarctic animals and plants. The average thickness of the Antarctic ice sheet is about 2400m, covering an area of about 13.9 million km2, accounting for more than 70% of the total land ice and freshwater on the earth. It is the coldest place in the world, with an average annual temperature of minus 25 and a minimum temperature of minus zero at the pole.

The Antarctic ice sheet began to form 26 million years ago and reached its current size 5 million years ago. After that, the Quaternary Ice Age was experienced, and the ice sheet expanded more than 1,000 km into the sea, occupying almost the entire continental shelf. About 10,000 years ago, as temperatures rose again, the ice sheets began to retreat.

In particular, in the past half century, due to the impact of global warming, the average summer temperature of the Antarctic Peninsula has risen by about one, resulting in an accelerated rate of melting of the Antarctic ice sheet. Since the 80s of the 20th century, the amount of ice in the western part of the Antarctic Peninsula has decreased by 20 percent, many ice shelves are gradually disintegrating and crumbling, icebergs are breaking away from ice shelves, and glacier fronts floating on the ocean are retreating at an accelerated pace. If the planet continues to warm, perhaps in a few hundred years, we will see the entire melting of the Antarctic ice sheet, the global sea level will be **60m, and all coastal countries will be affected.

The melting of the Antarctic ice sheet is sending us a strong warning that the trend of continuous global warming will not be stopped, and humanity is on the verge of extinction.

Harsh climates are more prone to hazards. The total area of the Antarctic continent is 13.9 million square kilometers, which is equivalent to the area of China and the Indo-Pakistani subcontinent combined, ranking fifth among all continents in the world. The entire Antarctic continent is covered by a huge ice sheet, with an average elevation of 2,350 meters, making it the highest continent in the world.

There are more than 220 kinds of minerals in Antarctica.

On February 9, 2020, a weather station on Seymour Island, Antarctica, recorded news of high temperatures.

Antarctica is divided into two parts: East Antarctica and West Antarctica. East Antarctica extends from 30°W to 170°E and includes Coates Land, Queen Maude Land, Enderby Land, Wilkes Land, George V Coast, Victoria Land, the Antarctic Plateau, and the Pole.

It covers an area of 10.18 million square kilometers. West Antarctica is located between 50°W and 160°W, including the Antarctic Peninsula, Alexandria Island, Ellsworth Land, and Bird Land, covering an area of 2.29 million square kilometers. Antarctica has only a few scientific expeditions and whaling teams from other continents.
