You're missing my point. Collective Gatherings, even for the purpose of keeping the totality alive, are. not. Civilization. The things which make Civilization require the presence of that spark of greatness inside humankind that you apparently wish to deny even exists. Ants do not provide an example of Civilization or even Barbarian-level culture (which in itself contains some admirable traits). As you pointed out, they provide nothing but the totality, the hive mind or collective intelligence. Civilization does not rest on a single individual of whom all others are mere extensions, it relies upon the differences between individuals.
And I will say that you are wrong (absolutely) in assessing right and wrong as nothing but imaginary, relative constructs of humankind. Or are you saying that there might be some condition under which it would be right for you, as you are now, to kill me, as I am now, or vice versa?
Right and wrong form the foundations of our civilization and any culture developing off of it. To attempt to run a culture of any sort without them would lead to pure chaos.
As to Greenpeace and PETA, or any other groups like them, I suppose these are the kinds of groups that'd cheer at the following legal decision. I can't remember the case name, or the year, sadly.
A brazilian monastary attempted to have termites living underneath them legally evicted. (I believe the purpose of this was to allow them to exterminate the pests, but cannot recall for certain.) The judge declared instead that the monastary would have to cede some of their own holdings to the termites, on the grounds that the termites were there first and so had prior legal claim.
