By the way, ozone blocks UV. Do you know how much ozone in the atmosphere it takes to block all the UV coming through?
Another fundamental error from the side that claims to have a monopoly on science. I suppose you think the beach keeps the waves from washing over the entire land as well. Like the beach, ozone is a result, not a cause. Chemically, in the upper atmosphere, ozone is formed when UV radiation breaks apart O2 molecules. The O molecules then bond to O2 molecules and form O3. It is the dissipation of energy used in breaking O2 molecules that, in reality, protects us from UV. Of course, O3 blocks some small amount of UV as well, but since it is a very unstable molecule (half life in the atmosphere measured in minutes) it requires much less energy to be broken. The ozone layer is the result of O2 saving us from harmful UV.
Another interesting thing about the ozone layer... Since sunlight reacting with O2 results in the formation of O3, where would you expect there to be an ozone shortage? Three guesses. At the poles during their respective winters is where there would be the least ozone since there is the least direct sunlight there.
In fact, when the party that first proved the ozone "hole" went to the south pole to research, they fully expected to find a hole, precisely because that would be where the least sunlight was hitting the atmosphere. As they passed through England on their way to the north pole to observe the hole form there during its winter, they mentioned what they found to the press and the rest is hysterical handwaving history.
Rather than report that the team found the hole they expected to find for the completely natural reason it was there the press reported "WE ARE ALL GOING TO DIE"...and algore took advantage and outlawed freon in favor of a "substitute" that one of his largest campaign contributors just happened to manufacture. From there, research money became available and the hoax lives on.

Ozone is a powerful oxidizing agent, far stronger than O2. It is also unstable at high concentrations, decaying to ordinary diatomic oxygen. It has a varying length half-life (meaning half as concentrated, or half-depleted), depending upon atmospheric conditions (temperature, humidity, and air movement).
In a sealed chamber, with fan moving the gas, ozone has a half-life of approximately a day at room temperature[13] Some claims have been stated that ozone can have a half life as short as a half an hour in atmospheric conditions, although this claim is not verified by this reference:[14]
2 O3 → 3 O2
This reaction proceeds more rapidly with increasing temperature and increased pressure [
just the sort of conditions one finds in the stratosphere]
Ozone Layer
Location and production
The highest levels of ozone in the atmosphere are in the stratosphere, in a region also known as the ozone layer between about 10 km and 50 km above the surface (or between about 6 and 31 miles). However, even in this "layer" the ozone concentrations are only two to eight parts per million, so most of the oxygen there remains of the dioxygen type.
Ozone in the stratosphere is mostly produced from short-wave ultraviolet rays (in the UVC band) but it can be also produced from x-rays reacting with oxygen:
O2 + photon (radiation λ < 240 nm) → 2 O
O + O2 + M → O3 + M
α + β− + O2 → He + O3
where "M" denotes the third body that carries off the excess energy of the reaction. The thus produced ozone is destroyed by the reaction with atomic oxygen:
O3 + O → 2 O2
The latter reaction is
catalysed by the presence of certain free radicals, of which the most important are hydroxyl (OH), nitric oxide (NO) and atomic chlorine (Cl) and bromine (Br).
In recent decades the amount of ozone in the stratosphere has been declining mostly because of emissions of CFCs and similar chlorinated and brominated organic molecules, which have increased the concentration of ozone-depleting catalysts above the natural background.
Importance to surface-dwelling life on Earth
Ozone in the ozone layer filters out sunlight wavelengths from about 200 nm UV rays to 315 nm, with ozone peak absorption at about 250 nm.[22] This ozone UV absorption is important to life, since it extends the absorption of UV by ordinary oxygen and nitrogen in air (which absorb all wavelengths < 200 nm) through the lower UV-C (200–280 nm) and the entire UV-B band (280–315 nm). The small unabsorbed part that remains of UV-B after passage through ozone causes sunburn in humans, and direct DNA damage in living tissues in both plants and animals. Ozone's effect on mid-range UV-B rays is illustrated by its effect on UV-B at 290 nm, which has a radiation intensity 350 million times as powerful at the top of the atmosphere as at the surface. Nevertheless, enough of UV-B radiation at similar frequency reaches the ground to cause some sunburn, and these same wavelengths are also among those responsible for the production of vitamin D in humans.
[
The comments here, particularly those showing different wavelengths absorbed by ozone than by diatomic oxygen, indicate that OZONE ABSORBS UV independently of oxygen.]
The ozone layer has little effect on the longer UV wavelengths called UV-A (315–400 nm), but this radiation does not cause sunburn or direct DNA damage, and while it probably does cause long-term skin damage in certain humans, it is not as dangerous to plants and to the health of surface-dwelling organisms on Earth in general (see ultraviolet for more information on near ultraviolet)
