JANDALA, Pakistan - Nassem Kausar has done it. So, she says, have her sister, six brothers, five sisters-in-law and two nephews. Each has sold a kidney to a trade that has led Pakistan's media to dub the country a “kidney bazaar.”

“We do this because of our poverty,” said Kausar, who is in her 30s and lives with her family in Sultanpur Mor, a village in eastern Pakistan.

A kidney nets the donor $2,500, sometimes less than half that amount, while recipients - some 2,000 a year - pay $6,000 to $12,000, compared with $70,000 in neighboring China.

Critics blame an economic system that enmeshes farmers in chronic debt, forcing them to sell their kidneys, and say the trade should be banned. The government says it is taking action.

In the United States, donating kidneys for money is banned.
