I was getting to that. The percentage from a single volcano is great. Perhaps several years of man's total emissions from all his artifical of sources. But volcanoes are rare. You can just about name all of the ones in your lifetime. Pinatubo, St Helens, a couple from Hawaii, Iceland, Popacatapetl,Vesuvious.
Cattle too, emit large amounts of greenhouse gases in most unpleasant ways. And forests although carbon dioxide sinks, end up being sources from two ways, emitting and fires.
The only thing I can say is we are adding to it in a significant way, so if we are by a certain percent cutting off the places we can live, so be it, we cannot complain about it in that case.
We may end up living in the sea to avoid the suns rays and keep cool. I will build myself a concrete shelter at a depth of about 30 feet, with a shark fence, and a flue to the surface for ventilation. Should be able to live on flounder and seaweed. Energy from waves, wind and sun. Call is Seahab 2000+ Go to surface put on the double sunblock and go for a sail for relief from Subaquaclaustra syndrome. A window on the sealife like Nemo had in his submarine would be calming and entertaining.
