The Antarctic waterfall is red in blood, flowing for hundreds of years, or related to a kind of creature

Antarctica, also known as “the Seventh Continent”, is the most desolate place on earth. It is not only the last continent discovered by human beings, but also the largest “no man’s land” in the world. The reason for this is that few people can live in such a harsh environment for a long time. Except for a few creatures that can adapt to the cold environment, no one wants to live in Antarctica, which also makes Antarctica a a world The least inhabited place on earth.

But Antarctica actually has great research value. The history of glaciers here can be as long as 200000 years, some even more than millions of years. Moreover, due to the cold climate in Antarctica, there is no man-made damage, so it still maintains its original appearance. In Antarctica, a series of changes have attracted people’s attention. Scientists have found that compared with the past 100 years, Antarctica is no longer a “pure land”, and it has changed from a “paradise” for animals to a hell.

We can clearly feel that global warming has spread to the polar regions of the earth, and more than two million tons of ice are now disappearing in the ocean, while Antarctica is also in danger. Moreover, in addition to scientists’ extreme concern about sea-level rise, a terrible creature is quietly waking up, that is algae, which is reported to have suddenly turned blood red near the British Antarctic observatory.

Scientists can study and analyze the past climate change and history of the earth by studying the bacteria in the air and glaciers. In addition, there is another fascinating place in Antarctica, the famous “blood waterfall”. “Bloody waterfall” sounds terrible, but it does exist. It’s on the desolate land of Antarctica. But in fact, the “bloody waterfall” in Antarctica has nothing to do with homicide or horror stories, it’s just carbohydrates formed after iron oxidation.

The researchers found that the culprit is a kind of algae called Chlamydomonas, also known as “monocytic algae”. This kind of algae will change differently in different environments. They should not have appeared in Antarctica, but as the temperature rises, they wake up from the soil, and under the action of ultraviolet rays, monocytic algae, which was originally green, turns bright red.

Finally, the scientists focused on the source of the “blood waterfall”. They found that the source is a huge underground ice lake. When it condenses, it will produce heat, thus releasing a large amount of clear water containing iron. Once the water contacts with the air, it will become a terrible bright red.
