What is cloning?
Cloning is when you take DNA from a living thing and make an embryo and implant the embryo into a surrogate mother and it makes a baby. because they want to find out if they can make more animals and try and play God just to see if it would work. They can use this technology to save threatened or endangered animals. There are some animals that have been cloned like a sheep called Dolly and she was born in 1996 in scotland and died in 2003 and it lived for 6.5 years and OX that has lived for only 2 weeks there is also a Goat that was in China and a horse that was born in 2003.
What is de-extinction?
De-extinction is when you bring an animal that is already dead back to life. Some bad reasons to bring a dead animal back to life is because it is way to expensive because if you pay for it and waste all your money and the de-extinction doesn’t work then you wasted all your money for no reason and also people should start to think about saving the animals that are threatened and almost dying then trying to save an animal that is already dead.
