Scientists Discover Antarctic Ocean Has Cleanest Air on Earth

Scientists from the Colorado State University’s Department of Atmospheric Science have discovered that the Antarctic Ocean has the cleanest air on Earth. The team set out to determine how far the wind could carry air pollutants produced from human activity. The scientists theorized that the air over the Antarctic Ocean would have the lowest concentration of these artificial aerosols, which originate from burning fossil fuels. To find out if their theory was correct, the team measured the composition of the air in several areas of the Antarctic Ocean. Upon studying the air samples collected, the researchers found that they did not contain any man-made chemicals. Instead, they found bacteria that were likely to have come from the ocean. The study’s lead author even commented that the team had difficulty obtaining particles to observe because the air was so clean. According to one of the researchers, the absence of human activity near the Antarctic Ocean was a factor behind the absolute lack of pollution in the surrounding air. Prior to the study, the researchers thought that human activity would have some degree of impact on every area of the world. However, the results of the study proved that there are still places that remain pristine and unaffected by pollutants. Before the discovery was made in the Antarctic Ocean, the place that was hailed to have the cleanest air in the world was Cape Grim in Tasmania, Australia.
