This is the idea that all citizens should be presumed, unless they have signed a waiver, to have agreed to allow their organs to be used in the event of, for example, their death in a car crash. Yet 'automatic opt-in' is unreasonable and undemocratic. It is best opposed in a free society. Yet remember the need. In the United Kingdom, approximately 6000 people are waiting at any one time for transplants of major organs - especially kidney, pancreas, heart, lung, liver.
Thousands die needlessly.
In the United States, at any time 70,000 men and women are waiting for a transplant of a major body organ. But the annual number of transplants in the US is only about 20,000. The National Kidney Foundation of the USA estimates that 50 Americans die every week for want of a kidney donor alone. Hence there is a missing market, an economist would say. So here we have an area where governments must step in.
