What is Bio-Ethics?
• The study of the ethical and moral implications of new biological discoveries and biomedical advances, as in the fields of genetic engineering and drug research
• Examples?

Current Bioethical Issues
Check the local news paper Stem cells (state, national, international) Genetically Engineered Organisms Knowing your genes In vetro fertilization – choosing your child's
genes and characteristics Chemicals exposures – human health Environmental health

"Biology combined with diverse humanistic knowledge forging a
science that sets a system of medical and environmental
priorities for acceptable survival.“Global Bioethics (1988)

1973 – Roe V. Wade Unrestricted access to abortion1978- First Test Tube ever born80’s - Recombinant microorganism could be patented,
lead is harmful to developing brain90’s - molecular biology, sequencing of human
genome (other species), Jurassic Park1996- Dolly the sheep is the first Mammal ever cloned00’s - US stem cell research restricted2003- Human Genome project complete? - Human cloned?

IVF – In Vitro Fertilization Baby conceived in a test tube and
implanted in a Uterus Available since 1986 About 100,000 IVF kids in U.S. Often creates extra embryos some
would like to use for Stem Cell research.
U.S. - About 400,000 frozen embryos (unregulated)
England – 52,000 (regulated by government)

Controversies:
Should a mother be legally liable for drinking or doing drugs while pregnant? This of course would cause harm to their unborn child.
Opinion?

Controversies:
• Should you be allowed to genetically modify your children before they are born to prevent disease?
• What about to change eye color, make them taller, stronger, smarter, better behaved?
• Opinion:
