There are limited resources on Earth. There is a finite amount of oil, metals, and resources to make health care goods. Right now health care is rationed by who can pay the most. When Obama care takes effect it will be rationed by other means. The only way to eliminate rationing is to reduce the number of people who use those resources.
The world population doubles every 60 yrs. In order to keep polluting this planet at the same pace we are now we would need to double our efficiency every 60 yrs. This rate will destroy the planet. The industrialization of countries shortens this time.
The only solution to preserving this planet for future generations and ensuring an adequate share of resources to all is population control. By reducing the birthrate this goal can be achieved.
