Ozone (O3) is an allotrope of oxygen, so obviously there can be no ozone if there is no oxygen somewhere. There is negiligible amounts of oxygen on Mars, yet there is a detectable amount of ozone there. Carbon dioxide may actually be supplying some of the oxygen required to form it...
Life based on RNA only has been discovered high above the ozone layer.
It is expected that life existed in the oceans, that could spend little time near the surface where UV-B could penetrate without an ozone layer.
There are single celled organisms that have DNA shaped into rings, so that breaks will be easier to repair, and these organisms can live in locations where even hard radiation is found.
*Some* life would be possible, just not human life.
The most notable role played by ozone is the screening out of harmful solar radiation.
The ozone layer absorbs much of the biologically harmful ultraviolet (UV) radiation coming from the sun.
The ozone layer is in the lower stratosphere approximately 20 to 30 kilometers (12 to 19 mi) above Earth.
The ozone layer traps the sun's heat rays in the earth's atmosphere. If an ozone layer did not exist, there will not be a way for the sun's rays to stay in earth's atmosphere. As a result, the earth will be very cold.
For a while, undergound. But we'd have no food, then no oxygen.
See "What would happen if the ozone layer vanished?" in the "Related questions" section below.
No, humans cannot live on a planet with no ozone. This will cause the UV to destroy the civilization.
Yes. Life on land could not exist without an ozone layer.
This is the stratosphere. There is also ozone in the lower troposphere, but the ozone layer in the stratosphere contains helpful ozone that blocks much of the ultraviolet radiation. Without this layer, life on earth would be very difficult.
There were no organisms before the ozone. Human life was not evolved.
Whether you believe man has anything to d o with the thinning of the south poles ozone or not, you should care about this layer. Without this layer we would have severe problems with too much UV-B. The ozone layer is absolutely responsible for the ability of life to exist on this planet.
Ozone is a layer of importance. It is the reason for life on earth.
Life on land may not have been possible wihtout the development of the ozone layer.
Ozone layer melting is very bad. Without ozone layer no life would be there.
When the ozone layer is completed, mankind would perish. There is no life without ozone.
Yes. Life on land could not exist without an ozone layer.
When the ozone layer is formed, the life forms evolved. They were not possible earlier.
This is the stratosphere. There is also ozone in the lower troposphere, but the ozone layer in the stratosphere contains helpful ozone that blocks much of the ultraviolet radiation. Without this layer, life on earth would be very difficult.
Destruction of ozone is an important issue. It is because without ozone there will be no life.
There were no organisms before the ozone. Human life was not evolved.
The ozone layers is a boon for life. Living organisms cannot survive without it. It is found in the stratosphere in atmosphere.
Ozone layer protects life. It does so from UV's.
Whether you believe man has anything to d o with the thinning of the south poles ozone or not, you should care about this layer. Without this layer we would have severe problems with too much UV-B. The ozone layer is absolutely responsible for the ability of life to exist on this planet.
Ozone is a layer of importance. It is the reason for life on earth.
