lol, yes it is, even if all nations collaborate, which is highly unlikely, the plain and simple truth is the everyone and everything consumes natural resources to some degree, when the is to much life then there is resources, those lives will end. We can see it in a petri dish that holds bacteria in a lab. They can exponentially multiply in an incredible short period of tine. But eventually, they suffocate in their own waste, they can no longer breathe, and their food supply is diminished. Their own population growth is killing the bacteria. No matter how much they work together, they will all die. All we can do is delay the inevitable. It has happened to the human race thousands of years ago, the only way to survive is to expand beyond their normal habitat into other locations, the problem now is there is nowhere to expand to now. (Unless of course as I stated earlier, interstellar travel becomes possible.)
But one other problem with the above argument, let's say for a moment that the CO2 production from industries and people is causing GW, any combustion reaction creates CO2, solar power is just isn't economically plausible to convert the entire world to. Fire creates heat, which in turn create carbon dioxide. This is the sole source of industry and human technological advances. As the population grows, CO2 production can't stop.
