DE-EXTINCTION

     The term de-extinction refers to bringing back extinct animals with stem cell technology. Theoretically, if scientists have body tissue from an extinct animal, they can clone this extinct animal.
     The first method would be extracting DNA from the animal's cell and transfer its DNA into another kind of animal's egg cell, which has its nucleus taken out. After an electric shock, this egg will start dividing and form an embryo, which will develop into the extinct animal.
     The second method is comparatively new, which is to stimulate the extinct animal's cell to change back to an embryo state -- stem cell, and it will develop into an embryo.
     However, this technology is not mature. Scientists have had successful experiments, but the produced animals always die shortly after birth because of complications, especially lung defect.    
     A lot of people are against de-extinction and argued that if this technology matures, scientists will be able to bring dinosaurs back to life and what was depicted by Jurassic Park will happen in real life. Additionally, people should not play god.
     Those who are in favor of de-extinction claim that it is only possible to clone animals that died out within a few years because there is not adequate body tissue of extinct animals from earlier times. They also state that people are already playing god by destroying animals' habitats and endanger their existence, so why not play god and bring them back?
     Nevertheless, cloning is not the way to solve extinction because people cannot produce mass amount of clones and the clones will have an extremely small gene pool, which will not help produce robust offsprings. Additionally, if people do not improve the environment these clones live in, they are still going into extinction.
