This was barely coherent and mostly doesn't touch on what the article purports.

The growth rate in your western country is pegged, as a matter of policy. It's met through immigration. Whether you have kids or not is neither here nor there; they will meet their target (note that carbon footprints are high in the West, and low in 3rd world countries, to the extent that marginal differences in growth in the 3rd world are irrelevant). This will subside when the global growth rate falters, which is already projected to happen. This can be accelerated by a) improving universal access to contraceptives, and b) improving 3rd world economies through trade and just regulation. In the interim we still need to improve efficiencies in the short-run to curb carbon emissions immediately. Obviously, not having kids has zero impact on this either. Innovations like renewables, seaweed-infused animal feed, etc are entering the market and will help bridge the gap, made possible through political will and investment from the financial sector in the order of trillions.

Don't have kids if you don't want them, surely. But don't pretend it makes a dent in the environmental crusade, and by extension, don't judge parents for a natural desire to start a family.
