The first line graph illustrates the ozone hole size over Antarctica from 1980 to 2000. Whereas the second line graph shows the production of three gases that can damage the ozone layer during the same period. Overall, the size of the ozone hole with a fluctuation increased. Meanwhile, the production of CFC-11 decreased significantly, while CFC-12 and N2O increased gradually.
Regarding the first graph, the size of the ozone hole was under 500 square Km in 1980, from there it rose significantly, reaching almost 2000 square Km in 1990. Following that, it experienced a drop of 1000 in 1993. Then, the size of the hole rose gradually until 2000, reaching approximately 3500 square Km.
In terms of three gas emissions, the production of A was almost 70 tonnes in 1980, where the emission of B was one-third of it, and C did not exist. The yield of A before a dramatic fall has a constant rise, then it dropped significantly to under 20 tonnes in 1995. While the production of B rose gradually, reaching approximately 50 tonnes in 2000. In addition, the production of C was started in 1990, from there it increased and reached about 25 tonnes in 2000.
