Re: what flora/fauna has the highest chances of survival after nuclear war.

Dear Aidis
Literally no flora and fauna would survive the effect of Nuclear war....
Some plants do have ability to withstand the effect of the normal Ultra Violet radiation coming from 
the sun since they have pigments or protective chemicals in them....but animals including humans 
are severily effected since they do not have the protective chemical, just by sun's radiation (that is 
Ultraviolet radiation).  You may have heard about bad sun burns in people....
So....the radiation of a Nuclear war...which would be far far stronger than the ultraviolet radiation of 
the sun would burn everything on its way...leaving burnt and dead flora and fauna.....

This is why use of nuclear weapons and nulcear war is a bad thing.....

A nuclear bomb once exploded.....litrally destroyes everything on its way....

this is a very simple explanation...i hope it answered your question

best of luck
