I thought that the organ transplant list was international. Maybe that is the bone marrow donor list.

I'll do a google search.
I can see your point about limited number of organs. It is supply and demand. Unfortunately, the demand outweighs the supply. A way to combat that is to be willing to donate your own organs. Most people don't want to think about things like their sudden, premature death and their organs. I'm reading about organ
donation. It's very informative.
