I’ll also add to this article a point that I’ve already made on my website, which is that population control is ideally best done through self-control, followed by contraception, where a couple gives in to sexual impulses. Self-control is best for spiritual, mental, physical, and all-round development. Spiritually, self-control weakens bad sexual habits and tendencies, prevents the sustaining and creation of desires which binds the soul to the physical body, and strengthens will power and concentration which can be applied positively in meditation, devotion, and right activity—yama and niyama.
Population control is the elephant in the room of sustainability. The control part ought to, and ultimately must, lie principally with the responsibility of every individual.
