This is very un-evenly distributed growth however. Developed nations are at or below sustenance level birth rates and largely rely on immigration to break even. As countries develop, birth rates decline -- this is well documented and incredibly striking. Check out this graph of birth rate vs. HDI [1]. As the rest of the world develops, the curve will invert and turn negative, it's just a matter of time.
Aren't we past the point of having too much? Making plastic single use goods obsolete and reducing all the Amazon purchases that get used once if ever would reduce total output. More focus could be put on quality (I know this can't be defined) products, rather that just driving blind consumerism.
That doesn't necessarily need to be so. Developed economies often end up with below-replacement birthrates (see japan-- it's the direction the western world is headed)
