While I think this is a good approach given population pressures have major consequences (wilderness shrinkage, land use, overuse, resource depletion, desperation, etc) education is a big factor as well as opportunities for women (there are countries where underemployed women are forced to barter sex for goods). Also changing customs is important. Many men push back on condoms, though not other forms of prophylactics, so it’s important to make other birth control widely available and change perception around them.
