Most of that is social construct.

Our biological imperative is too simple for most people to fathom-- if you concern yourself only with the welfare of yourself and your family, you're doing your part for the species by expanding it with viable offspring.

If ensuring the survival of you and yours means paying tribute to the local warlord or toeing a party line, then concern for the neighborhood or country will follow.

But make no mistake, it's not in your interests for the species to thrive. It's in your interests for your own offspring to thrive. Nature can't maintain its balance if the sick and infertile reproduce and the boundless demand for limited resources result in us driving everything else to extinction until we all run around sticking punji knives in each others' guts for lack of food anyway.

Of course the reason we should fight global warming is that it will have huge deleterious effects on humans that are avoidable. Yes, I agree, "the planet" will continue with or without us, but most people would prefer the "with us" option.

Finally, you end with "All we are doing is making the earth more suitable for humans to live, that’s it." What?? Tell that to the billions of people that live along the coast, or say anyone that lives in Bangladesh.

I think you misunderstood the meaning of that sentence. I mean "the effort to counter global warming" is to make the earth more suitable for humans to live, not the lack of effort.
