Band 6+: The graph shows the size of the Ozone layer hole in the Antarctic and three productions of damaged gases to the Antarctic Ozone from 1980 to 2000. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The two line charts illustrate the area change of Anatarctic Ozone layer hole and the amount of different Ozone-toxic gases over 20-year period.

Overall, Ozone layer increased gradually through the entire period. H2 and H2N3 showed a trend of slight increase, while H2O2 declined significantly.

Ozone layer size arose by approximately 220 millions across the period, illustrating minimal engagement in the first decade and fluctuation of beneath 50 millions from 1992 to 1996. It reached a eventual value of rough 250 millions.

H2O2 hovered the highest postion of over 150 millions in the first decade and was surpassed by H2 and H2N3 consecutively in the next decade due to its maximal drop of over 200 thousands. Noticeably, H2 and H2N3 both saw similar increase rates in the last decade with merely nuanced engagement in the first decade. Finally, H2 and H2N3 reached a value of around 160 and 70 while H2O2 droped towards nearly 0.
