Humans were always in a fight with viruses; it was a little victorious when humans discovered penicillin. Now, humans are facing serious problems since bacteria are starting to improve their antibiotic resistance.
As the climate is changing, Scientists have been arguing about the possibility of the frozen soil releasing some new and fatal bacteria humans don’t know anything about.
In august 2016 in the Siberian Tundra, there was an illness hidden and locked inside ice; it was released to injure people. As a result, a 12-year-old boy died and about 20 people were injured but later treated with anthrax.
Scientists believe that anthrax is rooting from a reindeer which was dead more than 70 years ago. They also think it was locked under permafrost. Therefore, when the permafrost melted in 2016 because of a heat wave, the anthrax was unleashed.
Researchers are not certain if such an incident will repeat itself or not.
“Permafrost is a very good preserver of microbes and viruses, because it is cold, there is no oxygen, and it is dark. Pathogenic viruses that can infect humans or animals might be preserved in old permafrost layers, including some that have caused global epidemics in the past,” Biologist and member of France’s Aix-Marseille University, Jean-Michel Claverie, said.
Debates About Concerns
However, some bacteria may never come back to life. It is debatable whether humans should concern themselves about the threats climate change will cause or not. Claverie believes that it is possible that dormant and asleep microbes may come back to life and harm humans.
“How likely that is not known, but it’s a possibility. It could be bacteria that are curable with antibiotics, or resistant bacteria, or a virus. If the pathogen hasn’t been in contact with humans for a long time, then our immune system would not be prepared,” Claverie stated.
