Remember 1985? I was only 4 but I remember it vividly, life was simpler (or maybe it just appeared to be). I remember sitting on the back of my mum’s bicycle as she took me to nursery, I had little hand-me-down shoes that my mum had painted red, we had scorching hot summers, snowy winters and a huge hole in the ozone layer.
The world was shocked when the British Antartic Survey revealed details of their findings – a gaping hole had appeared in our planetary protection – and we were to blame. I doubt I remember this announcement, I don’t think I watched the News at 10 back then. But I do remember growing up as a kid with a constant message about CFC’s. It turns out that seemingly innocent ‘chlorofluorocarbons’ were the culprit for earth’s new sun roof. This non-toxic, non-flammable mixture was regularly used in aerosols, foam, solvents and in fridges, but what we didn’t know was that when it enters the atmosphere UV rays break its bonds leaving Chlorine free to steal oxygen – from the ozone.
Do you know what we did about it?
The world rallied together – a convention was held in Vienna and 193 nation states agreed to the phasing out of CFCs. 2 years later they were banned and 30 years on and the ozone layer is recovering – this just shows what we CAN do, if we want to.
