The ozone layer is in the stratospheric region of atmosphere. Its role is to protect us from the harmful ultraviolet radiations coming from the earth.
Ozone layer is a layer or pool of ozone molecules. It's role is to stop UV rays from the sun to entering the earth's surface.
Oxygen has no role as such in the atmosphere, its importance is related to when it is removed from the atmosphere, as in respiration and/or oxidation.
Ozone layer blocks the UV rays. These are fatal for sustaining life on earth.

The ozone layer in the upper atmosphere has a vital role in protecting the inhabitants of earth. It blocks the harmful ultraviolet radiations which could be very fatal.
CFC's deplete the ozone layer. They react with ozone to decompose it.

Important is the role of ozone in the atmosphere. It protects us from the UV rays of the sun.

Ozone layer plays a very important role in survival of life on earth. It blocks around 97% of the radiation received by earth. It acts as an blanket keeping the atmosphere on earth cool and habitable.
Scientists didn't knew ozone layer before 1880. It is because of lack of technology at that time.
The ozone layer protects the earth from harmful UV rays from the sun. All those CFC's actually tear holes in the ozone layer, but they take 50 years to reach there. So the last CFC's in the atmosphere, sprayed in 1972, won't even start tearing apart the ozone layer till 2022!
