The ozone layer filters out incoming radiation in the "cell-damaging" ultraviolet (UV) part of the spectrum. One example of ozone depletion is the annual ozone "hole" over Antarctica that has occurred during the Antarctic spring since the early 1980s. The effects of ozone depletion range include poor air quality, imbalance in bio-geo-chemical cycles, loss of biodiversity and a negative effect on aquatic and terrestrial ecosystems. However, tackling the issue of ozone depletion is one of the greatest environmental successes we have achieved on a global scale. Listen to find out how we did it, why we did it and what we can do to keep our very useful ozone layer intact.
