Because there has been an ozone hole (in all likelihood) for 500 million years, every year.

How long will it take until the Ozone layer breaks down if people don't do anything about it?
See "When will the ozone layer be gone?"
Will you die when the ozone layer breaks?
Yes, you will. There is a lot of time until the ozone breaks up.
It is thought that life could not have existed on land until the ozone layer formed about 2 billion years ago. Why does life on land require an ozone layer?
Because the ozone layer provides a thin layer of protection from the harmful UV rays or ultraviolet rays.
How much of ozone layer has been destoryed until now?
Ozone over the poles has been destroyed. It is due to the fact that ozone is susceptible to low weather.
When did ozone layer develop?
See "It is true that life could not have existed on land until the ozone layer formed about 2 million years ago Why does life on land require an ozone layer?" in the "Related questions" section below.
How long does ozone stay in the atmosphere?
Ozone is a very unstable molecule. The energy required of formation of ozone is much greater than the reverse process that is the formation of oxygen and nascent oxygen. However there is an ongoing process of formation as well as depletion in the ozone layer which makes its concentration in the ozone layer constant. However due to the CFC's the rate of depletion is increasing thus creating an ozone hole in the ozone layer.
Can you protect the ozone layer by planting more and more trees?
CFCs (chloro-fluoro-carbons) are harmful to the ozone layer. they used to be used in aerosol sprays and fridges until scientists discovered they were causing holes to form in the ozone layer. they aren't used anymore, but some developing countries are still producing them. ban the use of CFCs worldwide, and you would definitely help stop the destruction of the ozone layer.
Is it through that life could not have existed on land until the ozone later formed about 2 billion years ago why does life on land require an ozone layer?
Life on earth requires an ozone layer. It is because it absorbs the fatal UV rays of the sun.
How big was the hole in the ozone layer in 1880?
There is no way of knowing. We did not discover the recurring ozone hole until the late 1900s.
Why wasn't ozone depletion a problem until the 20th century?
i dont know because your dumb
How is carbon dioxide affecting the ozone layer when it is a heavy gas?
Carbon dioxide is causing the temperature of the ozone layer can cool. This allows the CFC's to accelerate the ozone depletion.
Can the hole in the ozone layer be closed?
Yes, it closes up naturally after the sun returns to the area each spring. Without the sun, it is impossible to maintain the levels of ozone at the poles, thus the thinning occurs each winter until the "hole" occurs late winter or early spring. As long as we have sunlight and oxygen, the hole will close each year naturally.
