Well, good! Many of our environmental problems would be easier to solve if there were fewer of us. The fact that humanity has collectively and voluntarily chosen to make this happen is one of a very short list of reasons to hope that civilization might get through the next century-plus of ecological crisis.

Many countries--United States being an easy example--fell for the meme of putting women (the historical and biological primary caregivers) in the workplace and demonizing and denigrating men as a demographic.

Compounding all of this, we've made distractions more omnipresent while lowering the quality of relationships and wrecking the onboarding process for either of the majority genders/sexes.

We've destroyed our future so that we could drive down the price of labor, signal how progressive we are, and play pretend about how children happen and are raised. At least two entire generations have been damaged in this way, and the people that aren't are not the people one probably wants to take over society (full quiver folks, etc.).
