The high demand for organs and long waitlists have been met with a corresponding expansion of the illegal organ trade. Currently, it is estimated that about 10% of all transplants occur illegally, with the Internet acting as a facilitator.[75] One source estimates that at least 4000 prisoners were executed in 2006 to supply approximately 8000 kidneys and 3000 livers for foreign buyers.[75] In 2007, 2500 kidney transplants were purchased in Pakistan, with foreign recipients making up two-thirds of the purchasers.[42] As of 2007, the Voluntary Health Association of India estimated that approximately 2000 Indians sell a kidney every year. In the same year, in Canada and the United Kingdom, experts estimated that about 30 to 50 patients illegally purchased organs abroad.[44]
