Hmm – a colony of ants would be considered in an ‘unnatural’ state if it began to destroy the ecosystem on which it depended. To that, ants and other systems of life seem to have checks & balances that limit irreversible destruction but humans do not—or we don’t anymore. We have been out of sync with the ‘natural’ order for thousands of years if not longer; so, perhaps in that sense it is now our nature? Or perhaps it always has been humanities nature – our only salvation has been the fact that Earth is so big to accommodate our mishaps. However, as the population grows the Earth does not and the margins for error shrink.
