I suppose the Sahara is a myth? The balance of the climate is maintained by various species, not by magic.

The problem isn't the volume but the rate of change. Which is not to say I am sure that the sky is faling, just that it is silly to state categorically that it could not do so. One of the major polutants that gets `belched' into the atmosphere is oxygen, I assume that no piddling little micro-organism could ever totally change the composition of the atmosphere? -- rjc@cstr.ed.ac.uk
