Is it selfish to have more than two children?

Is it selfish to have more than two children? The implication of even asking the question in this context of course is that it is selfish and irresponsible. I would argue the complete opposite. Once one realizes that humans are not a burden but our ultimate resource, it becomes clear that 3+ children per family are not a problem. See the links below re: Julian Simon's work in this area. The fears appears to be little more than unfounded Malthusian nonsense.

And the name 'Sustainable Development Commission' scares me more than a little, very Orwellian.

BBC NEWS - Is it selfish to have more than two children?: "Is having more than two children selfish? The future of the planet rarely plays a part when planning a family, but that's got to change, say environmental campaigners. Parents who have more than two children are "irresponsible" for placing an intolerable burden on resources and increasing damage to eco-systems, says a leading green campaigner. Curbing population growth through contraception must play a role in fighting global warming, argues Jonathon Porritt. This week, the Optimum Population Trust (OPT), of which Mr Porrit is a patron, launched its "Stop at Two" online pledge to encourage couples to limit their family's size. "Every additional human being is increasing the burden on this planet which is becoming increasingly intolerable," says Mr Porritt, who runs the government's Sustainable Development Commission."
