Presentation Transcript

  1. Biotechnology & Bioethics The Bio-Revolution

  2. Biotechnology • The application of scientific and engineering principles to biological agents to provide goods and services to better human life • Many moral issues today are centered around genetic engineering via the manipulation of DNA

  3. Ethics • Moral philosophy • Discipline concerned with what is morally good and bad, right and wrong

  4. Bioethics • Discipline dealing with the ethical implications of biological research and the applications of that research • Deals with the questions relating to the appropriate use of new technologies

  5. There are no simple answers to ethical dilemmas…. • What will cause the greatest good for mankind?

  6. Eugenics • An effort to breed better human beings • Encourage “good genes” • Discourage “bad genes” • Fear of history – Sterilization of the mentally ill in early America Nazi concentration camps

  7. Reproductive Cloning • Creating a genetically identical organism • Many animals have been successfully cloned

  8. Human Cloning • Clonaid claims that they have the ability to clone humans

  9. Therapeutic Cloning • Cloning Individual Human Cells • Involves Stem cells – precursor cells that give rise to specialized cells/multiple tissue types • Allows for the generation of human tissue and organs • Enhances our understanding of human development and serious medical conditions (cancer, birth defects, etc) • Embryonic vs Adult Stem Cells

  10. PreImplantation Genetic Diagnosis (PGD) • Diagnosing inherited genetic disorders “in vitro” • Choosing which embryos will be transferred to the uterus based upon desired traits • Gender decisions • “Designer Babies?”

  11. Genetic Testing • Individual risk assessment based upon a person’s DNA profile • DNA chip identifies genetic predispositions • Potential for genetic discrimination • DNA profiling? DNA banks?

  12. Transgenic Plants • Engineered plants that contain novel genes from other species • Results in new characteristics that make plants more desirable and useful to humans • Are they safe to eat? • How do they affect the ecosystem?

  13. Transgenic Animals • Engineered animals that contain novel genes from other species • Results in animals that are more desirable and useful to humans • Are they safe to eat? • Where do we draw the line?

  14. Xenotransplantation • Harvesting organs from animals for organ transplantation into humans • Severe Organ donor shortage • Pigs – Perfect match! • Do we have the right? PETA • Dangers of Creating New Human Viruses

  15. Finding a Balance • Focusing on whether or not “we could” • Instead of whether or not “we should” Weighing the Pros versus the Cons Acknowledging the tremendous responsibilities that must be faced with the information that we have acquired.
