Of course there is, human activity generates heat, and heat melts ice.
This is dumb. First, we have thousands of people already living in Antarctica and they aren't melting ice, especially enough ice to displace thousands of people.
I was clearly talking about selfishness of the individual making the point that individual humans will look after themselves over the rest of their species - this is why we even have things like racism in the first place.
That still makes it a dumb comment since your example was of colony-based insects who are notoriously colony-focused. They are far more racist than humans, viciously competing with even with their close kin in other colonies.
It's pretty clear that you are blinded by your opinions and merely assume that approaches which you deem bad, like terraforming the Sahara are automatically bad and approaches you deem good, like moving a vast number of people to England (and overwhelming its infrastructure), are automatically good. The real world doesn't operate that way.
