    It's a tragedy (悲剧)that could be avoided: every year, more than 400 people in Britain die while waiting for a replacement organ for their bodies. Although organ transplants(器官移植)have been saving lives for more than 60 years, the right body part is often not available at the right time simply because not enough people choose to be donors. Should people therefore be required to allow their organs to be used by others after death?

The British Medical Association (BMA), which represents doctors in Britain, says yes. A system of "presumed consent (默许) " would automatically make everyone over the age of 16 an organ donor .Individuals would be allowed to put out, that is to say, decide not to be an organ donor, if that's what they prefer. The BMA points to much higher organ donation rates in countries that have opt-out systems, such as Spain, Belgium, Austria and the Czech Republic.

England's chief medical officer, Sir Liam Donaldson, also wants to change the organ-donor system from opt-in to opt-out. All of this sounds like very good news for the 7,500 people in the UK who are waiting for transplants of critical organs, tissues, skin and bones.

Britain's National Health Service (NHS) recently counts 14.3 million organ donors on a list which began in 1994. Not everyone wants to participate, however, according to the NHS, 90 percent of the British strongly support organ donation, but only 23 percent are on the organ-donor list.

Why the discrepancy(差异)? One reason is that organ donation is a personal matter. Another reason may be indecision: when families are not sure about a dead relative's wishes, 40 percent decide not to donate his or her organs. Interestingly, religion has little to do with a decision not to donate. All six of the main religions in Britain support organ donation and transplantation.

The government decided in 2018 how the system of organ donation should work--- without a policy of presumed consent. Opinion among members of parliament (议会) continues to be divided; but the tragedy goes on: as things are now, one in 10 Britons in need of an organ will never get one.
