[QUOTE="Dry Rot, post: 7849576, member: 4505"] I haven't read the whole thread as I'm convinced I am numerically dyslectic, if there is such a thing! I learnt about something called The Carbon Cycle at school. Plants absorb carbon dioxide from the atmosphere using photosynthesis with sunlight to make cellulose which is what makes wood. That's why you can put a barrow load of fire wood on the fire and get only a few handfuls of ash. Put the ash on the soil and the process is repeated, with carbon dioxide and other residues going up the chimney as smoke,,,,to be reused later to make wood. That process goes around and round in a circle (or cycle) so it evens out. But millions of years ago, forests died and were left to form oil, gas, and coal. We are now using these fossil fuels, tipping the balance. So there is an excess of carbon dioxide. The panic is now to shove all this excess CO2 back underground where it came from. That, very basically, is what it is all about. Sorry lads, can't be done. We are dooomed! Imagining that millions of years of carbon build up in the fossil fuels that have been converted to produce energy releasing CO2 can be put back where it came from by planting a few trees is just plain stoopid.
