We may contribute a small amount but the greater increase in change is due to the increased volcanic activity in recent years much much more than anything we could ever do.Have to admit I haven't read what was posted since my last post, way too much to get in before work. I'll read over it when I get a chance later and if I see anything that changes my opinion I'll be happy to post as such. Do we pollute our environment? Absolutely Do we do harm to our air quality and drinking water? Absolutely Do we put enough green house gasses into the atmosphere to make an appreciable difference in global climate? In my opinion and from what I have seen and read, No.

I learned all I need to know about life by killing smart people and eating their brains.
