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.

The two-line graphs depict the

size

of the

ozone

hole

over Antarctica and the three damaging gases to the

ozone

layer.

Overall

, a glance at the graph reveals that CFC and N20 are the gases that cause the most damage to the

ozone

layer in the

last

two decades of the twentieth century.
