How is the ozone layer depleted?

• The abundant amount of CO2 released is reacting with the ozone (O3), thus making the protective layer thicker.

• The abundant amount of CO2 released is reacting with the ozone (O3), thus making the protective layer thinner.

• The O2 is affecting the O3, this making the ozone layer thinner.

• The O2 is affecting the O3, this making the ozone layer thicker.
