It would be pretty much impossible for another intelligent species to appear on earth now without relating to human beings as a context. I mean, the relationship I was groping for above is Synanthrope[1]. Basically, an entire ecosystem of animals eating and using human garbage already exists - what else do you imagine these animal eat? Giving animals some training to also pick-up said garbage seems neither better nor worse than the status quo.

Plus, I don't think anyone will be doing any explaining to the crows - if the crows rise, they're be using fire and poison to exterminate them in the fashion we would use if one another species seemed to threaten our dominance.

Unless we create them. There will always be a point that the apex predators fail to recognize the threat until it is too late.
