In the Dark: Mr. Bennett's article "Dark Green" about the Medea Hypothesis of Peter Ward in the January 11, 2009 Sunday Globe was phenomenally interesting . I love it when new theories arise which tug on the reins of credulity and say wait a minute not so fast. Things may not be as one thinks they are. I had heard of the Gaia Hypothesis which seems to be the prevailing thought that the earth's contents (minus man) work in some earthly harmony to produce life until evil man ruins everything. It seems so rational. Yet, when one thinks about it the earth has experienced upheavals threatening its existence long before man appeared on earth. Moreover, one sees the destructive nature of our planet's power in times when man's influence was not so dramatic.

My own totally unscientific thought is that our planet is influenced by both things humans do and things humans do not do. I suspect it is neither all one nor all the other but both. How interesting it would be to live to see what happens. One wonders if man will control his own harmful influence on the planet, which I believe does exist, and, perhaps, even right the wrongs the planet perpetrates on itself. It is simply fascinating science theory. No matter what one believes it proves one thing; life is, indeed, precarious.
