Who should have children? Those who are responsible and completely dedicated to the responsibility which is actually a very small percentage of humans. Being a parent should be a career.

As for myself, I do not believe in loggers, I believe in trees. I do not believe in fishermen, I believe in fish. I do not believe in miners, I believe in the rocks beneath my feet. I do not believe in pie in the sky spirituality, I believe in rainbows, rivers, mountains, and moss. I do not believe in environmentalists, I believe in the environment. I am a proud traitor to my species in alliance with my mother the Earth in opposition to those who would destroy her, those parasites who believe the Earth is here to serve human interests.
