Researchers say they have found the first clear evidence that the thinning in the ozone layer above Antarctica is beginning to heal as the the hole was around 4 million sq km smaller than it was in the year 2000.
Credit must go to the greens in the mid-80s who campaigned to ban ozone-destroying chemicals CFC's found in everything from hairsprays and refrigerators to air conditioning units.
Since the global ban on the use of CFCs in 1987, the situation in Antarctica has been slowly improving and are now showing first signs that the ozone protective layer is actively growing again.
Even though we phased out the production of CFCs in all countries, there's still a lot of the chemicals left in the atmosphere and as it has a lifetime of 50 to 100 years it will be a slow process and to a complete recovery but it should provide an inspiration that we may have royally messed up the atmosphere but with international co-operation governments, science, industry and us everyday folks can work together to protect our natural world and come up with solutions to tackle our spiraling global environmental problems if we have the will.

Shame there is not more of it, would solve so many problems.
