If so then we are under supreme time pressure to come up with the answers. An ozone hole over the Antarctic may appear like a distant threat but at current
rates of increase it may not be long before it begins to threaten large centres of population.
But just why is the ozone hole so important and why could it become dangerous?
Massive umbrella.
In plain language the ozone layer acts somewhat like a massive umbrella that prevents us receiving too much ultraviolet radiation. Less ozone naturally means
not as much protection, leaving us wide open to skin cancer, cataracts and disorders of the immune system. If the ozone hole were to grow much bigger it would mean wider swathes of humanity would face a significant
problem. Taken to extremes it could pose an immense hazard to the whole of humanity. If for example the ozone layer were subject to severe depletion then even five minutes exposure to strong sunlight would be enough
to cause intense burning.
Long term future.
With the reduction of chloroflurocarbons in the atmosphere, ozone depletion should pose no more than a “temporary” hazard. In this respect “temporary”, probably
means in the order of 30 to 40 years. The trouble is that in the short term the problem is getting worse, and although this was expected, the staggering rate of increase has taken experts by surprise. It may
also mean we have not fully understood the problem or the way it is perpetuated. If for instance there is an accumulative effect to ozone depletion, we could soon be faced with a nightmare situation within a very
short time.
This makes it all the more imperative that the problem is fully understood before it becomes too late to deal with it!
