Man is very arrogant, to think that we should be the judge and jury of every species on the planet. We need to remember that we only one of countless other species of this planet and to be good neighbors.
Change is inevitable, it's probably my biggest gripe against people that are vehement about global warming, this idea that nothing should ever change. Just because a bird species used to stop at this place means that it should always stop at this place.
Ridiculous post is ridiculous.
We shouldn't be the "judge and jury", as you say. The problem with global warming is that we ARE being the judge and jury - we're condemning thousands of species to death for no reason at all through our own voluntary actions. We should be trying not to do that as far as possible.
Basically, you are confusing inaction in the face of some natural change with "inaction" in the face of huge change caused by our own actions. I.e., you are apparently in favour of some random action, but not action to undo that action.
Your bird species point would make more sense if there were thousands of places for the birds in question to stop. On recent human form, though, there's a decent chance that these birds and this place may have taken on a species-defining importance. Wipe them out here and that might be it for them. We are intelligent and aware that our actions have consequences, so we should work out whether this is the case and try to avoid wiping them out.
Yes, there have been big changes in the past. But human-induced climate change has the potential to rank with a major catastophe on an evolutionary timescale.
