For my regular visitors, if you find that this blog hasn't been updating much lately, chances are pretty good I've been spending my writing energy on my companion blog. Feel free to pop over to Home is Where the Central Cardio-pulmonary Organ Is, and see what else has been going on.

Food for thought, as well as plants...

By David Bellamy and Jack Barrett


Carbon dioxide is not the dreaded greenhouse gas that the global warmers crack it up to be. It is in fact the most important airborne fertiliser in the world and without it there would be no green plants at all. In fact, a doubling of the levels of this gas in the atmosphere would bring about a marked rise in plant production -- good news for everyone, especially those malnourished millions who can't afford chemical fertilisers. Perhaps the time is ripe to really start worrying (again) about the fact that for the last 200 million years the concentration of carbon dioxide in our atmosphere has been falling. Indeed it dropped to dangerously low levels during recent ice ages. The Plant Kingdom responded to this potentially catastrophic (no carbon no food) situation by producing the so-called C4 plants that can survive low CO2 by using sunlight more efficiently.

Please talk to your plants -- and as you do, rest assured that they in effect will thank you, by recycling your waste carbon dioxide to make more plant material and return oxygen to the earth's atmosphere.
