Tuesday, 1 September, 2009

I’m not sure that my dentist would approve of me cancelling visits on the basis I’m trying to reduce my nitrous oxide footprint, but given that happy – or laughing – gas emissions are having a damaging effect on Earth’s ozone layer it might be time to consider curtailing the use of the gas. Or going to the dentist if you’d prefer to go that route.

“Right now, nitrous oxide is the most important ozone-depleting gas that is emitted,” says A. R. Ravishankara of the US National Oceanic and Atmospheric Administration, lead author of the new research. “It will continue to be so unless something is done.”
