CO2 Is Helping the Ozone Layer to Recover

I know you guys don't like that because you're so anti-CO2.
Get over yourselves, okay? CO2 is an important atmospheric gas.
Decreasing its emissions could be harmful to the ozone layer. This
is because CFCs and other ODSs are as toxic as some people in
this forum.
Haven't you guys learned anything about atmospheric chemistry
posting with me in here? That seems to be missing. Would you like
to discuss the ozone layer and why CFCs were banned? No?
And yet you're debating climate change (it happens) and atmospheric
chemistry. The real problem would probably be ODSs and hydrocarbons.
But then some will say look at the pretty pictures and we'll see glaciers
melting and CO2 levels rising.
Did Al Gore change his name to Duncan IBDM (a play on Dunkin' Doughnuts, what police eat when fighting climate change).
And why do we need an ozone layer? It literally protects the food chain that supports life on Earth. If it becomes depleted enough then phytoplankton and food crops will become damaged on the cellular level.
This is a "holy" link because I don't have a pretty picture to show anyone.
Anne Rammelsberg, a chemistry professor at Millikin University, offers this explanation:

Ultraviolet (UV) light kills cells by damaging their DNA. The light initiates a reaction between two molecules of thymine, one of the bases that make up DNA. The resulting thymine dimer is very stable, but repair of this kind of DNA damage--usually by excising or removing the two bases and filling in the gaps with new nucleotides--is fairly efficient. Even so, it breaks down when the damage is extensive.

Am hoping some of you guys can read.

p.s., if rails under a train were shorter than 1/2 of a truck (the space between 2 wheels) then a truck could bridge the gap because 2 wheels would always be on a rail. Too many gaps and then the train becomes unstable.
