People live longer, healthier, and more productive lives than during any previous era.
We send humans into space and communicate across the globe in seconds. We treat previously untreatable diseases, perform our jobs more quickly and efficiently, and enjoy the benefits of technology in virtually every aspect of our lives. For the most part, this is a good thing. However, policymakers occasionally face difficult moral questions over what these advances mean to society. Besides splitting the atom, I can think of no scientific breakthrough this century with so profound a moral dimension as human cloning.
