That is the Gaia concept, that Nature defends herself. Another example is that there are definitely bad effects from burning out the Amazonian forests, but the effects are more muted than expected. Fewer forests mean more carbon dioxide in the air. Forests live on carbon dioxide. They love it and it helps them grow.
Forests grow thicker all by themselves and turn carbon dioxide into oxygen.
Killing off forests fosters growth in other forests and Nature has once again defended itself. So the Gaia people are partially correct. There is no conscious spirit in nature, but nature really does defend itself. But Duncan THE MT VOID Page 4 may be assuming a bit much when he suggests that nature is going to have a ready response to nuclear weapons and that the natural restoring force to the effects of nuclear weapons is for nature to cough up some flying pteranodons to counteract the effects. This just does not sound like a cycle that Nature would have seen very frequently in the past.
