If the use of CFCs were not decreased, then this is the amount of ozone left.

This is how CFCs destroy ozone.

Ozone depletion

Most people know that ozone is the O3 layer that surrounds our Earth, but they may not realize that there is a giant hole in the ozone just above the Antarctic.

The ozone layer had holes even before the 1970s, when people started using CFCs (chlorofluorocarbons) and HCFCs (hydro chlorofluorocarbons).
It depleted the ozone so much that when scientists measured the ozone in September 13 2007, they found a 24.7 million square km hole in it!

The ozone layer protects us by shielding 93-99% of the Sun’s harmful ultraviolet (UV) rays. Without ozone protection, the UV rays can pass through skin et cetera and attack DNA.

We can save the ozone layer by stopping deforestation and decreasing the amount of moisture let into the atmosphere. Some organizations are dedicated to saving the ozone layer. ‘The Ozone Hole’ is one of them.

Save the ozone, save our future.
