Overpopulation

Many people are afraid to have more children. They add to a already too large population competing for scarce resources. They increase the pollution and add to the CO2 destroying our planet. They are to expensive to raise and take too much energy. Throughout our culture we are encouraged to have as few children as possible.The first of our 613 Commandments is not only that we must have children but also to have many. Is that really a good idea? Are we not afraid of the harmful results of irresponsibly having children? What about people who cannot or did not have children? Are they missing this commandment? Do they have an alternative?
