As far as limiting children goes, I agree that it would be good (although I don't put my money where my mouth is, since I have four children.) However, when we get into China's one child, forced sterilization policy, we tread into dangerous territory. No one should have to endure a forced abortion. I would be against any serious hardships imposed upon women. What if a woman were pregnant because her birth control failed, even though she was conscientious? Would she have to be faced with a choice of forced abortion or a high dollar penalty? If she can barely afford the child, a high penalty would only make it less likely for the child to have good nutrition and all the things a child needs. However, I agree in spirit that voluntary limits should be in place. And, if you average out kids in my family, I think we come out with a net plus for the planet, since none of my children, ages 39,37, 28 and 19, have had any children yet. That's unusual. They are trying to save the planet by being environmentally conscious (and probably making up to planet Earth for Mom, lol.)
Yeah, gays may be our ticket to saving the planet, lol. I like that idea, even though I'm not gay. There should be more freedom of choice.
