Cloning of organisms such as mammals has been done for decades, but still with varying success. So far, most cloned animals die just before or after birth. Nonetheless, cloning has the potential to lead to some exciting (yet controversial) benefits:
- Agriculture and Drug Production – for example Polly, a transgenic cloned lamb, is able to produce milk containing factor IX — the protein that is deficient in haemophiliacs.
- Maintaining biodiversity – endangered species could be preserved if currently practiced methods fail.
- Treatment for Human Disease – cells could be harvested from early embryos to provide cell and tissue replacement without the hazards of transplantation rejection.
Statement: Cloning for beneficial reasons such as the ones above, far outweigh the risks.
