no worse than the Passenger pigeon, the Dodo bird, various other island (and mainland) creatures that thrived prior to "civilization" having discovered their lairs.
Who was here for T-rex's disappearance? Who vainly fretted about the peterosaur's demise? Where were the caring when millions of other creatures came and went thru the eons???
We humans are NO DIFFERENT than a mega-volcano or a giant asteroid impact - except, unlike those catastrophes, we recognize ourselves as such. But this rock has NEVER been about continuity. Never. It coalesced out of bits of stellar detritus and morphed from an inhospitable blob to a lab for the spark of life to play upon. Of course - we fancy ourselves so fucking smart - but we're not. IF we were of truly superior intellect, we'd figure a way to put a hold on everything JUST AS IT IS. The best we can do at this point is scurry around - collecting and preserving DNA bits in the vain hope we can reverse the degradation of natural habitats and turn back the clock.
We're a catalyst for extinction - quite possibly our own. We COULD maybe take a lesson from that unspoiled tribe that was recently contacted in the tropics. They - like native Americans of the recent past - lived in harmony with their surroundings. But who of we civilized sorts is ready to give up their flat screens and spend our afternoons skinning some hapless monkey for the evening meal? Who? Yeah - I thought so.
