@Aliesending,
While bromine is nearly 100 times less abundant than chlorine, it is about 10 times more effective in depleting ozone. Volcanoes are potentially a very important source of atmospheric bromine. Other natural sources include certain brine wells, the Dead Sea, and ocean waters. The bromine emitted from volcanoes is likely large enough to cause local ozone depletion and affect stratospheric chemistry.
Now that is an article i found in about 2 minutes on the web. I'm not saying that man doesn't contribute to the chemical arsenol that depletes the ozone. but a syncronized eco-system will naturally rebuild the ozone layer odviously, the earth is alive. it's your dooms day THOUGHTS that create what YOU focus on, you must not know how powerful of creators we humans are, our THOUGHTS control the world we live in, now...wrap your skeptical mind around that
