In recent decades, our specific knowledge has developed incredibly fast. Genetic engineering processes are now widely adopted especially in the agricultural aspect. Some scientists now even suggest using cloning technology, which produces an entire life from a single cell, in pursuit of increased food production. Nevertheless, the potential benefits it brings to the general community cannot outweigh its harm.
To begin with, cloning is obviously against nature. From the beginning to the end of the world, life and death is something that all living things can only accept, but not to decide. We, human beings, are just a tiny part of the enormous world. None of us can be rid of the rules of nature supporting all our lives. Without the Mother Nature, there would not be us. It is our basic responsibility to respect her.
Besides respecting the Mother Nature, we also have to protect her. Cloning and other genetic processes create unnatural lives that are alien species to the wild lives. The products of these processes often possess some adaptive advantages over the natural species. When they are released to the environment, either by accident or deliberately, they always out-compete the originally colonizing ones, causing the natural organisms to die out. This will eventually become a biological disaster that destroys biodiversity heavily. The above stated is absolutely not just an extreme or theoretical case. It is of paramount importance for us to remember that the cloned organisms are living things, and are very unpredictable. They can move, reproduce, and even mutate. Will they interbreed with other organisms, creating new species? Will they threaten other organisms? Once released into the environment, they cannot be recalled. To prevent them from getting into contact with other organisms and causing biohazards, they should not be produced from the very beginning.
There are actually far more unpredictable problems apart from the effects of the cloned organisms on the environment. What if an error arises during the cloning process? It may still be fine if the cloned thing is a plant because no one will feel upset for it and the destruction of it will not cause any ethical controversy. How about a cloned animal which suffers from a painful disease? Should the scientists abandon it or kill it? If the former one is chosen, people would blame them for their cruelty of not letting the animal escape from its pain. If the latter is chosen, people would complain that they infringe animal rights because a cloned animal is still an animal after all! A fundamental question then arises: who has the right to decide?
Finally, all of us will find out that no one on the Earth has the right to control lives, neither the fate of a life nor the creation of a life. Humans have already done too much that interferes with the lives in nature. When can we learn to respect our environment, respect lives, and respect ourselves? I hope the day would come before we are penalized by the furious Mother Nature.
