The two line graphs illustrate the changes in the ozone hole size over the Antarctica region and the amount of three gases produced which caused damage to the ozone layer between 1980 and 2000.
Overall, there was a significant increase and CFC - 12 and N20 mainly gave rise to the expansion of ozone hole over Antarctica over the period.
The ozone hole was at its smallest size of about 400 thousand square kilometres in 1980. But 20 years later, it grew drastically to 3. 6 million square kilometres by nine times excepting for a reduction in size from 2 to 1.2 million square kilometres in the early 1990s.
In 1980, about 70 million tonnes of CFC - 11 was produced, which remained stable for 3 years before undergoing a steady decline to below 10 million tonnes in the late 1990s. The production of CFC- 12, on the other hand, showed an upward trend throughout the 20-year period from 25 to 50 million tones, surpassing the production of CFC- 11 in 1989. N2O, however, was not produced until 1990, but its production grew rapidly to about 40 million tonnes in 2000.
