The line graphs show the size of the ozone hole in Antarctic and three types of damaging gases that damage the Antarctic ozone from 1980 to 2000. Summarize the information by selecting and reporting the main features, and make comparisons where relevant

The line charts below display the thousands of square kilometres of the ozone

hole

and the gases that harmed it between 1980 and 2000.

Overall

, there is a significant increase in the ozone

hole

size over the entire time

period

. Freon fell dramatically,

while

NO2 grew steadily. At the beginning of the

period

, the size of the ozone

hole

was just below 50 thousand square kilometres, and in the next five

years

rose moderately to around 80. From 1985 to 1990 it climbed sharply to a little under 200, in the

last

10

years

the

hole

continued to climb slightly, ending the

period

at approximately 240. In 1980 Freon was the most produced gas, with nearly 150 thousand metric tonnes, in the next five

years

it rocketed considerably to 200. From 1985 to 2000, it decreased rapidly to just over 20, becoming the least produced one.

Furthermore

, NO2, at the start of the

period

, had little under 100 thousand metric tonnes of production,

this

grew modestly until 1985, with 120, and in the

last

5 five

years

it rose steeply to more or less 160.
