There are a lot of spare kidneys in the world!

Legalize organ sales!

- Demolish organ harvesting, organ Black Markets, organ availability only to rich and powerful people in China!

- You don't need 2 kidneys, you only need one! Everybody is a ready donor. Virtually nobody will die from kidney problems or have to suffer dialysis.

- If everyone could sell it, great compatible organs will be available to everyone who needs it.

- If it is legalized, it can be formally regulated and accepted by society, eliminating the medical terror associated with organ transplants due to organ harvesting and other currently sick images we have of this.

- Speaking of medical terror, I think that's what is blocking a lot of people's minds from everyone becoming a donor. That, and you can't sell a kidney to buy Apple products.

Cryogenics, stem cells and all controversial medical procedures are cool and awesome in Futurama, so it's fine in real life!!
