" ... charging that the genesis dominion mandate is a license for selfishness, carelessness and destruction. adam was put into the garden to tend it,- which I suppose makes him some kind of conservationist!"

Yes, it does appear to be a licence for all of those things, doesn't it, pete? You may recall that when western Christians - and their priests - went to other parts of the world they not only enslaved and oppressed the people they found there but also trashed their environments. And this trashing is still going on and is accelerating. These days the religious elements have largely been lost but I reckon that, if you dug down, you'd find the toxic concept of "dominion" to be at the root of this catastrophic destruction.

" ... there are a number of other texts which teach care of animals and even trees."

What do you mean by AND EVEN TREES, pete? In your world, are trees 'lower' than animals?
