Yes, we should have laws that encourage organ donation, because that is a way to promote the public good. Many people die each year waiting for organs. If our laws could make a difference to have that not happen, it would be a great benefit to our society. The public should support laws of this nature.
We should have laws that encourage organ donation. Many people want to donate their organs, but they do not know how to sign up or participate in organ donation programs. If there was a law that made an easier way to opt in to these organ donation programs, many people's lives would be saved.
Rather, instead of laws, the best course of action would be a lack of laws. A free market for organ donation - or, rather the ability of people to walk into a hospital and sell a kidney, would serve to close a huge gap in the organ donor waiting list.
It would be nice if everyone were willing to donate their usable organs, but we shouldn't be forced to. It is each individual's right to decide what will happen to their body upon their demise. The government controls enough of our lives (and not with the best intentions) already. They can keep their noses out of our rights to our own bodies.
We should not have laws that encourage organ donation. It should remain a voluntary choice by individuals and not be a law created to encourage it. Most people donate because they feel it is a right thing to do. There are some people with religious beliefs that prevent them from donating. A law would not cause the donations to rise.
