No, you have indeed constructed a strawman argument based on prejudiced fears of third world 'population explosion' and poor data. Let me put aside the fact that third world peoples are not sitting around waiting for such explosions to occur and are proactive about and invested in our own resources and prospects. Let me put aside the comparison of the poorest, say, Indians (the strata where such an 'explosion' is likeliest to occur due to a host of social reasons) vs the richest, say, Americans. Even putting all that aside: the per capita consumption of an American is 10 times that of an Indian based on latest data [1].

And this does not at all take into account that so, so much of American consumer goods are manufactured abroad and does not factor into this calculation.
Really, please interrogate the kind of prejudice that leads to projections of the kind you have accepted, and the kind of prejudice that then uses it as a rationalization for not course-correcting own behavior.
