The graphs below show the size of the ozone hole over Antarctica and the production of three ozone-damaging gases from 1980 to 2000. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

To begin

, the line graphs provide information on how the size of the ozone hole in Square Km (in thousands) over Antarctica changed over a 20-year period of

time

and the amount of ozone-damaging gases released in Tonnes (in millions) during the same

time

.

Firstly

, the size of the hole increased significantly from 1980 to up until 1990 showing a value of approximately 2,000,000 Square Km even though, around 1993 a considerable decline in the trend can be observed.

Furthermore

, until 2000 the size of the hole had gotten bigger when it peaked at 4,000,000Sq.Km

range. CFC-11 was at its peak back in 1980 emitting around 70 million Tonnes

20 years later it shows a decreasing trend continuously

CFC-12 illustrates the opposite of that growing gradually overtime within the
