Given the fact that the advent of agriculture is really the only reason overpopulation is possible for us, technology is the base cause of our environmental problems. It also has allowed us to develop such relatively extravagant lifestyles. Overpopulation wouldn't be as big of a problem if it weren't for overconsumption. The amount of resources most of us use, it wouldn't matter if we had just enough humans to maintain genetic diversity, we'd still not have enough resources and the planet would be in much the same shape. Blaming it on overpopulation is, in my opinion, a convenient scapegoat since, no matter how people try to frame it, it essentially breaks down to "women need to stop having babies", so rather than it being on all of us, the responsibility for change rests solely on women, poor women specifically.
