The cleanest place on planet Earth is above the Southern Ocean — the totality of the southern parts of the Pacific, Atlantic and Indian oceans that surround Antarctica. We are talking about the air of the boundary layer of the atmosphere, which feeds the lower clouds above it.
It was this part that did not affect human activity. In particular, the negative effect of aerosol particles. This site is considered the cleanest, according to a study by scientists at Colorado State University, whose results
published in Proceedings of the National Academy of Sciences.
To determine the cleanest place on the planet, researchers used bacteria as an indicator of determining the key features of the lower atmosphere. Aerosols, which control the features of clouds over the Southern Ocean, are closely related to biological processes in the water.
The study showed that Antarctica is isolated from the spread of microorganisms and the deposition of nutrients from the southern continents. It turns out that the Southern Ocean has become one of the few places on the planet that has not been affected by human activity.
Previously, scientists reported that in the world there are more and more places that can soon become
uninhabitable. The reason for this is global warming and high temperatures in some areas of the world.
