The first line graph shows the changes in terms of the specification of the ozone home above Antarctic, and the second chart compares the amount three different gases causing damages to zone in 1980 and 2000.
It is clear that the sizes of the hold in ozone layer fluctuated over the 20-year period, and it was biggest in the year 2000. By looking at the numbers of the gas emission, CFC11 saw a steady drop during the given period, while both CFC-12 and N20 experienced different levels of increases.
In 1980, the size of the hole was the smallest, only around 60 square Km, and it had been increasingly enlarged to 2000 square Km by 1990. During the same period, CFC-11 was the major gas causing ozone damage, produced nearly 80 million tons in 1980, but it began to fall dramatically by half, to 40 million tons. There were only 24 million tons of CFC-12 at the beginning, and N20 were produced at this time.
The hole had been shrink for 5 years since 1990 before it jumped to its biggest size of 3,700 square Km. CFC-11 and CFC-12 were exhausted 40 million tones respectively, in the year 1990. Since then, Numbers of CFC-11 kept dropping at the same speed to merely 6 million tons in 2000, while CFC-12 reached it’s peak, at 50 million in the same year. N20 was firstly seen in 1990 and replaced CFC-11 to be a second contributor to ozone damage in 1995 with production of 20 tons.
