Given the worldwide food shortage, have you decided against having a(nother) child?

Population growth rates have exceeded food supply growth rates for six years now, and there is a worldwide food shortage and sharply escalating food prices. Dought affects major crop growing areas (e.g. Australia, etc.); farm land is disappearing to erosion and housing developments; the US uses more corn for ethanol than it exports; Mugabe confied all white-owned farms and Zimbabweans are now starving, whereas they used to export enough to feed half of southeastern Africa. What are you doing to reduce population growth? Have you changed your mind on your planned family size, or decided against having a child now?
