> I've seen many self proclaimed environmentalists straight up advocate and encourage women to never have children for the sake of the planet
OK, I think you're talking here about VHEMT [1] and the like, which is only very tangentially related to traditional [2] antinatalism. The latter is more a reduction-of-suffering philosophy, in much the same way that vegans/vegetarians/etc believe that it's better for an animal never to live at all than to endure the conditions of modern meat farming.
Obviously neither movement stands much chance of success since neither stands any chance of convincing an entire population. If they have any effect at all, the former will tend to eliminate genes associated with environmentalism, while the latter will tend to eliminate genes associated with unhappiness (which doesn't sound so bad).
