answer:I think saving a DNA bank of all endangered plant and animal species is an excellent idea. There are problems with cloning though, in that the animal cloned may have health problems due to aging of the original. In other words, if I took a DNA sample from someone in their 30s and grew a baby clone, that baby would have certain degradations from aging a “traditional” baby would not have. I believe the major factor (and I have no problems having someone clarify or correct this), is telomere degradation. Basically the ends of our chromosomes gradually degrade with age, and cloning someone who has already experienced some of this degradation will be passed on to the baby. In light of this, it is selfish to raise a child that will probably have health problems because I want a loved one back. Perhaps taking and preserving a DNA sample at birth or a young age to keep around “just in case” might be wise. I don’t have an ethical problem with that. More interestingly though, our understanding of the genetic code is rapidly increasing. As our knowledge becomes more complete, we’ll have the ability to design whatever the hell kind of organism we want. Is that ethical? It depends on what we design and what its intended use will be.
