What will come to life with melted glaciers? Have you ever thought that melting glaciers are not just water? Antarctica and the Arctic were once home to many extinct creatures. We are used to thinking that nothing that is dead can be resurrected. But is it? The latest frightening scientific information suggests that it is quite possible that we will face an epidemic of unprecedented proportions to humanity. The dead will indeed rise, but they will not be people. This is a completely another creatures. In 2018, Russian scientists revived ancient nematodes 42 thousand years old, all this time the worms spent in the permafrost in Siberia. In May 2021, Russian scientists revived frozen rotifers that had been in the ice for 24 thousand years. Having melted samples of Antarctic ice from one hundred thousand to eight million years old, scientists from Rutgers University (USA) investigated the microorganisms found there. Even bacteria from the earliest specimens showed faint signs of life. Bacteria from 100,000-year-old ice, placed in a warm nutrient medium, came to life and showed the ability to grow. The bacteria that had been in the ice for about eight million years had significantly weaker signs of life. These microorganisms were freed from ice taken in the Antarctic Beacon Valley, believed to be the oldest ice on Earth. In the arctic, a species of arctic worm has also been found that lives in temperatures below freezing. In 2002, a group of American scientists managed to revive microorganisms, which are estimated to be 2800 years old. These microbes were found in Antarctica in the ice near the surface of the underground Lake Vida, which is 19 meters deep. According to scientists, the water in the lake contains seven times more salt than normal seawater and does not freeze at minus 10 degrees Celsius. In 2005, American scientists discovered new types of bacteria. They slept for 32 thousand years in the ice in Alaska. The bacteria came to life when they were thawed. In 2008, scientists thawed strains of bacteria from the 1960s-1970s and treated them with several types of antibiotics. Surprisingly, however, not all bacteria remained dead after treatment with lethal doses of rifampicin and ciprofloxacin. So, it is quite possible that the resurrection of the dead really awaits us. But these will not be people, melting glaciers will bring not only new diseases, but also new types of parasites. These organisms have been dead for thousands of years, but after they thaw, they will come to life and begin to take over the environment. I believe we are facing a global biological catastrophe in the next hundred years.
