Where on earth is the cleanest air?

We all know very well about severe pollution.urban air and from time to time we get out of town or at least in a park. Regarding stuffy rooms, in parks and villages, the air is very fresh, but it can not be called clean. Many people walk in the parks, whose clothes emit microscopic particles of perfume, and cigarettes emit hazardous substances. You can’t find clean air even in villages, because agricultural machinery works everywhere, and cars are far from rare. But is there a place on our planet with truly clean air, without any exhaust gases and other substances produced by people? American scientists are sure that there is - they even showed where it is.

There is clean air on our planet, but it is far

Freshest air

Scientists quite logically suggested that the mostclean and fresh air in the world should be where there are no people. So it’s definitely not worth looking for a breath of freshness and purity over the USA, Russia and other countries - the air is so polluted that scientists do not even know how to clean it. And over the so-called Southern Ocean, which surrounds Antarctica and is a combination of the Pacific, Atlantic and Indian oceans, clean air is quite possible to look for. And what? There is solid water and, with the exception of occasionally flying planes and passing ships, there are no air polluting factors.

The crew checked this assumptionresearch vessel SOCRATES. Researchers traveled from the Australian island of Tasmania to the glaciers of Antarctica and occasionally took air samples. Basically, they were interested in what bacteria it contained. If the air in the proposed territory is really clean, then the bacteria would be exclusively "marine", that is, they would fall into the air directly from the water. But if scientists found bacteria of a foreign origin in the air, it would mean that they got there from the densely populated areas of our planet. From this, scientists could conclude that the vicinity of Antarctica is not well isolated from the rest of the world and there is no place on our planet with clean air.

Did you know that in our homes a huge amount of harmful substances and ventilation does not help to get rid of them at all?

Air purity

Fortunately, the air over the Southern Ocean reallyturned out to be clean. After studying the bacteria collected from the air, scientists came to the conclusion that they are of aquatic origin. As a result, they concluded that there are no air polluting factors in the vicinity of Antarctica. They are sure of the purity of the work done, because they handled the samples “like jewels” and conducted research in laboratories - so they were able to prevent air samples from becoming contaminated.

About this beauty can be seen in the place with the cleanest air on the planet.

From now on, we can assume that the cleanest air inThe world is located in the vicinity of the Southern Ocean. Only for greater persuasiveness, scientists should check which substances are contained in the air - this is very valuable and interesting information. For example, it would be good to know how high the concentration of ozone is there, which is the main enemy of human intestinal bacteria. In cities, the concentration of this gas is very high and it destroys 128 types of bacteria necessary for the proper functioning of our body.

In one of the materials I wrote that dirty air leads to obesity - this is just due to the above facts.

With all this, I readily believe that nearAntarctica has no 2.5-micron dust particles, which in the scientific community are referred to as PM2.5. Basically, they rise into the air due to the movement of cars and are components of asphalt and exhaust gases - there are few equipment in the ocean, so there are practically no sources of PM2.5. Their tiny size allows them to settle in the lungs and even penetrate the circulatory system to spread throughout all human organs. In the long run, due to these tiny particles, people get serious diseases and children are stunted.

So, one of the “freshest” places on Earthfound. Now it remains to hope that no rich man would dare to go to these places in order to breathe clean air, which is almost inaccessible to us in nature. For hundreds of years, humanity has greatly damaged the environment and realized its mistake too late. Yes, now many companies are trying to get electricity from the energy of the sun, and the car manufacturer is introducing electric motors into them that do not produce exhaust gases. But even with the best of circumstances, our planet will not be restored soon.

Perhaps the pandemic that began in 2020Coronavirus is an attempt by nature to recover from the harmful effects of humans. Many researchers report that after the closure of many plants, the air on our planet really became cleaner. My colleague Lyubov Sokovikova wrote more about this - I strongly recommend that you familiarize yourself with the material.
