From NewScientist: UK considers organ donation by default.

Should doctors assume that people are happy to donate their organs unless they make the effort to opt out? That’s the scenario being considered in the UK, as a means of reducing the widening gap between supply and demand for donated organs.

(…) Last year, a study of 22 countries found that donation rates were 25 to 30 per cent higher in countries with presumed consent, such as Spain, Austria and Belgium.

That makes more sense to me than our crappy system. Earlier on the nest: link link
