What are some real-world conflicts in the book Unwind.

In his novel, Unwind, Neal Shusterman
addresses numerous real-life, real-world issues.  Presumably the most obvious of the
issues touched upon in the story is that of the huge conflict between pro-life and
pro-choice supporters.  This conflict is the basis for the bill that is passed that
gives parents the choice to unwind their teenaged
children.

Some other societal concerns that play roles in
Shusterman's book are euthanasia, parental rights, terrorism, organ transplants
(especially considering what many find to be questionable scientific advances and
ethics), and religious extremists.  Shusterman does not shy away from bringing
controversial topics into play in his writing.
