A few people currently have posts up about breeding, children, and families. From musing on this, I am inclined to think that maybe we need to move towards something that will be very close to things that will make people very scared.
That mockery of a sentence is basically me saying: controls on reproduction may not be all that bad. It may be that the best situation for society is, speaking very broadly, one in which people do not operate with an expectation that they automatically have the right to have children. The principal reason is that more people require more land, more energy, consume more plastics, more minerals. The number of humans is way beyond the planet’s capacity to support at our current level of consumption. I think this is one good reason for people to make a personal choice not to reproduce. But personal choices may not be enough.
EDIT: This post sparked a lot of controversy, which I have partly responded to here.
