Ozone is very important to life on Earth because it absorbs 93-99% of the sun's harmful ultraviolet rays.
Ozone allowed life to leave the depths of the ocean and move onto land. Nitrogen and oxygen can and do absorb UV-C radiation from our Sun, but only ozone can absorb UV-B (which will break DNA... even through skin).

∙ 12y agoWell, we don't know that it was critical to the formation of life on land . . . what we do know is that the ozone layer was critical to the formation of -our- kind of life on land, because the ozone layer screens the Earth's surface from ultraviolet radiation, which would fry life as we know it. (Other kinds of life could in theory have been created that could only live under harsh ultraviolet light)
Even under the ozone layer, ultraviolet radiation from the Sun will kill you if your skin is exposed to it for too long. (sunburn is just a small part of this killing process . . . and even then, people die from skin cancers caused by bad sunburn - which is really ultraviolet cooking)

How is the the ozone layer important?
This question has been answered in other categories... It permits there to be life near the surface of the ocean, and on the surface of land.
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?
Life started to occupy the surface of the earth about about 475 million years ago (plants). Insects followed on land 400 million years ago and reptiles at 300 million years ago. The ozone layer started to form after the atmosphere became richer in oxygen due to the evolution of blue-green algae 2 billion years ago. As result the presence of life on the Earth's land surfaces was far removes (in time) from the creation of the ozone layer.The way evolution works is that the existing land life on Earth requires the ozone layer. However if the ozone was mission life may well have developed with alternate ozone protection (shells, UV reflective colours, a more UV resistant chemistry. present life would not do well in a high UV environment but this is not to say that land life could not have developed in such an environment.
Was there an ozone layer in the permian period?
Yes. Life on land could not exist without an ozone layer.
How did the ozone layer move animals to land from water?
It didn't. The ozone layer permitted plants and animals to move from the deep water to the water's surface, and eventually to land.
Why does earth have an ozone layer?
because if it was not there it would cause to much ultaviolet radation and that would kill usThe ozone layer plays a ital role in supporting life on land. It is because ozone blocks the harmful ultraviolet radiations which can cause fatal diseases on land creatures.
Why is ozone important to living things?
Because it Shields Earth from things like meteor(ites) by wearing them down to a tiny rock by the time it hits land or water, most of the time. Its important to all us "living things" by protecting us.
Is ozone harmful or beneficial at your land surface?
Ozone at land is harmful. It acts as a pollutant.
How did the formation of the ozone layer permit organisms to colonize land?
they stopped the harmful sun rays from penetrating and thus made the conditions for more suitable for life...

Why are decomposes important to the food chain?
They turn dead organisms into chemicals that norishes the land.

What is the term given to organisms that live both in land and water?
Land organisms and liquid organisms
How has the ozone layer allowed life to life on land?
The ozone layer has allowed life on land. It is because it prevents the harmful UV rays from entering the earth.
Was there an ozone layer in the permian period?
Yes. Life on land could not exist without an ozone layer.
