Animals can be reproduced by technology now; researchers can clone them. A clone is an exact copy of another animal or plant. Scientists have cloned a sheep which they have named Dolly. Researchers took genes from a ewe (母羊) and used them to create a copy (Dolly) of the ewe.
Why are scientists doing this research? One reason is to get information about genes so they can improve our health. They also want to learn how better farm animals can be produced. Cloning is a controversial issue for people. Some people think it is good because this research can help us, but other people think cloning is unacceptable. Some people think it might be possible to save endangered animals by cloning them. Tigers, elephants, and other endangered animals might be saved in this way.
In China, pandas are endangered because they are hunted and they are losing their habitat, so some Chinese scientists want to try to clone pandas to save them from extinction.
I don't really like the idea of cloning animals, but I don't think I want panda to become extinct. If the best way to save them is to make cloned pandas, they must be cloned.
I want to live with a lot of animals and nature. I don't want animals to die out, especially pandas. I think humans must think more about protecting animals and nature. Maybe cloning is the way to save all endangered animals.
