As the Ozone layer depletes above us, day in and day out we find new discoveries which further hurt our chances of recovery. In sunlight snow can cause the release of nitrogen oxide gasses which help deplete the ozone layer. Whats more is that it is found that impurities found in Arctic snow (some caused by climate change) can further amplify the process. Researchers found that snow with salt levels similar to those found in the wild released 40-90 percent more nitrogen oxide gas compared to snow which contained no salt.
This is important because it is just another problem that humans are going to have to face if we want to fix the damage we have caused to the environment. I worry things are going to become too much to tackle and we will never be able to fix our problems.
