Half of the world’s population at risk of UV radiation! Scientist discovered big ozone hole

Scientists have detected a large and all-season tropical ozone hole in the lower stratosphere. It is said to be quite large in size. This is as deep as the Antarctic Hole, but 7 times more in area. King-Bin Lu, a scientist at the University of Waterloo in Ontario, Canada, has uncovered this all-season ozone hole. It is defined as the ozone loss zone. The existence of this tropical (tropical) ozone hole can become a cause of concern worldwide. Explaining the reason for this, Qing-bin Lu said that the tropics account for half of our planet’s surface area and is home to almost half of the world’s population.

In the 1970s, many researches revealed that the ozone layer, which absorbs most of the ultraviolet radiation from the Sun, may be depleted by industrial chemicals such as chlorofluorocarbons (CFCs). The discovery of the Antarctic ozone hole in 1985 confirmed ozone depletion caused by CFCs. Although ozone depletion has decreased after the ban on such chemicals, evidence suggests that ozone depletion still persists.

reports Describing the dangers of the ozone hole, Qing-bin Lu said that the depletion of the ozone layer can increase UV radiation at the ground level, which can increase the risk of skin cancer and cataracts in humans, as well as damage the human immune system. and reduce agricultural productivity. It can affect sensitive aquatic organisms and ecosystems.

Scientist Lu’s observations of the ozone hole have puzzled the scientific community, as it was not predicted by conventional photochemical models. Reports suggest that ozone depletion levels in the equatorial regions are already threatening large populations and the UV radiation reaching these regions is much higher than expected. Scientist Lu says that this discovery can prove to be important for better understanding of climate change around the world.
