UNEP has designated 16th September as International Day for the Preservation of the Ozone Layer, and 2015 marks the 30th anniversary of the British Antarctic Survey’s paper in Nature alerting the world to the ozone hole and the adoption of the Vienna Convention for the Protection of the Ozone Layer in 1985. The Vienna Convention was followed by the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987.
The photograph shows knitted representations of the three main stratospheric ozone depletion equations: the breakdown of CFC-11 in sunlight releasing a chlorine atom, and the cycle of ozone destruction catalysed by this chlorine. It was released on Ozone Day 2015. The knitted representations are part of a work in progress.
