How would life on Earth be affected if the ozone layer got much thicker?

Short Answer: Until it intruded deeply into the troposphere, there would be no negative effect from more ozone More Detail Since depletion of the ozone layer provides these known problems: increases in cancer increases in mutation (aka. Birth defects) increases in cataracts decreases in crop yields increases in day / night temperature swings Then adding more ozone on a permanent basis would decrease incidences of cancer decease chances of mutation decreases in cataracts increases in crop yields possibly small increases in viable crop land decreases in day / night temperature swings, leading to perhaps slightly less severe storms A deepening of the blue of the sky If the ozone layer got very thick, say the atmosphere was bombarded by gamma radiation from some not-too-distant supernova, much of the oxygen and nitrogen in the atmosphere would be called on to absorb this energetic radiation. Most of that extra energy would be absorbed above the troposphere, but some of it would make ozone down closer to Earth's surface.It is already known how even small increases in normal ozone levels at Earth's surface is dangerous, if not deadly to Man, animals and plants.

We should have plenty of protection from UV-B, even if it is distributed differently So we'll have to see what happens, if it happens Note that the same radiation that ozone protects us from, destroys ozone. Also, ozone is unstable and decays with a "half-life" of hours to weeks (depending on temperature and contaminants) back to oxygen.So any upset making more ozone would have to be long lasting to have a long term effect.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
