Psychopathic policy initiatives
Well she is right, if we were to reduce population then more of her children could breathe clean air and drink clean water.
Now you couldn't have a negligible drop, it would have to be a very significant drop in population. I think this would be most noticeable in the slums of the world.
But the question I have is who is she referring to by "our children"? Is that simply the children of the elites? That really is the only thing that makes sense mathematically because if you were to reduce population evenly you would have less of "our children" not more.
But if you eliminated all the poor below a certain threshold, say a third of the world's population then it would be true that more of the elite's children could breath clean air and drink clean water.
