Before you worry too much...........................

.....about us humans messing with Gaia, consider this thought:


     In my home country, near a small town now almost vanished from the map, there is a region which remains to this day uncultivated.  It is best seen at nightfall, because it is then that the full mystery of the place seizes upon the mind.  Red granite boulders hundreds of miles from their point of origin thrust awkwardly out of the sparse turf.  In the last glow from the west one gets the impression of a waste over which has passed something inhumanely remote and terrifying - something that has happened long ago, but which here lies close to the surface.  Crows circle above it like disturbed black memories which rise and fall but never come to rest.  It is a barren and disordered landscape, which remembers, and perhaps again anticipates, the cold of glacial ice.  It has nothing to do with man; its gravels, its red afterglow, are remnants of another era, in which man was of no consequence.
