Jonathan Shanklin is a meteorologist with the British Antarctic Survey. Together with Joe Farman and Brian G. Gardiner he discovered the "Ozone Hole". He plays cricket, is a bell-ringer, and is a keen amateur astronomer, being Director of the British Astronomical Association's Comet Section [1].
In an article discussing the discovery of the "ozone hole", the BBC quotes him as saying
Perhaps the most startling lesson from the ozone hole is just how quickly our planet can change. Given the speed with which humankind can affect it, following the precautionary principle is likely to be the safest road to future prosperity [2].
