Ozone hole - still exists and requires more of our attention

The gap in the atmosphere over the Antarctic, namely the famous "ozone hole," may be able to self-repair within about half a century. However, some experts point out that the ozone hole is very fragile and still needs everyone's attention. The ozone layer protects us from ultraviolet-B radiation in sunlight, which can cause skin cancer and other hazards. When the thin ozone layer increases ultraviolet radiation, both animals and plants will suffer negative impacts.

Given the importance of the ozone layer, what we have done to protect it is far from enough, at least that's what the scientists who first discovered the ozone hole over Antarctica believe.

Dr. Joe Farman was one of the three British Antarctic Survey scientists who first reported severe damage to the ozone layer in 1985. He now openly criticizes the principle allowing developing countries to continue using ozone-depleting chemicals until 2040 and other principles he considers counterproductive.

Farman points out: "There are often comments on the Montreal Protocol..."
