Cloning - Ethics
Animal Cloning
Scientists wanted to clone an extinct Tasmanian tiger. Do you think this is a good idea, or a bad idea?

What are some possible ecological consequences of reintroducing a once-extinct species?

Does it make a difference if the animal is extinct because of human causes, or natural causes (for instance, the Tasmanian tiger is extinct because of human invasion on its natural habitat, whereas dinosaurs became extinct because of natural causes)? Should scientists try to “fix” the mistakes of humans who killed off the last of species?

Would you clone a favorite pet? Why or why not? Does cloning guarantee that the animal will act the same as the one you know?
Human Cloning
Should scientists be allowed to clone a human?

What makes cloning humans different from cloning animals?

Should scientists try to clone organs, so that organ donors are no longer needed?
