Is health care just a business like any other, or should health care professionals have a higher standard of ethics? Should we invent a pill that enables people to live for hundreds of years? Have parents the right to use science to design the kind of children they want? Does everyone have an equal right to health care, whatever it costs? Is abortion the same as killing babies? Should we create creatures that are partly animal and partly human? Is it OK to sell our body parts, such as one of our kidneys, like we buy and sell our material possessions, our cars or our mobile phones? Should the state force people to adopt healthy life styles? Should mercy killing be made legal? Does it matter if our current use of natural resources is likely to totally destroy the environment in a few years from now?
