The graphs below show the size of the ozone hole over Antartica and the production of three ozone-damaging gases from 1980 to 2000.
The line graphs provide information on the magnitude of the ozone hole over Antartica and production of gases that is damaging the ozone layer, namely CFC-11, CFC-12 and N2O, over the 20 year period.
Overall, the damage to ozone layer has increased considerably over time in relation to the production of harmful gases.
To be specific, it can be seen on the graph that the production of CFC-11 and CFC-12 in 1980 started of at approximately 70 million tonnes and 30 million tonnes respectively. During this time, the damage on the ozone layer is just about 400 kms. The production of CFC-11 significantly dropped to 20 million tonnes in year 1995 while the production of CFC-12 continued to increase steaduly until 50 million tonnes in year 2000. Though there is a decrease in CFC-11 production, the hole in the ozone layer became wider at 2000 kms in 1990 and started to decrease only after that to about 1,500 kms. People then begin to introdice the N2O in year 1990 and showed a steep rise in production to approximately 37 million tonnes in year 2000. Its effect is reflected on the chart when the size of the ozone hole picked up to 3,500 kms in year 2000.
