Genetic Engineering

There are many manipulations that humans have done to the environment throughout history in order to benefit mankind. As technology has increased many of these manipulations have begun to take place on a larger scale resulting in more drastic changes to the environment. The first manipulations humans used to benefit themselves were farming and domestication of animals. This was very basic manipulation to the environment and did not make drastic changes to the environment. It was not until the industrial revolution that pollution and people’s negative effects on the environment became very apparent. New technology allowed for people to make changes that could possibly be irreversible upon the environment. With

Other methods of Cloning up until Dolly used cloning by splitting embryos to create twins, or using artificial insemination. One of the downsides to cloning using this method is that the clones begin to age a lot faster making it impossible to repeat the process by making clones of clones of clones and so on. The problem arises that because there is less of a DNA strand passed on through the aged clones, the clones become more susceptible to mutation. Another negative effect of cloning is the prevention of evolution, in particular the immune system. Through sexual reproduction the evolved immune system is inherited by the offspring. Clones don’t get that new immune system. This makes clones susceptible to the same germs of the previous generation. "Without sex we’d soon be toast for germs. And cloned, genetically identical cows would be sitting ducks for epidemics." (Rantala, 189)

Biological warfare is one of the obviously negative effects of genetic engineering. By manipulating bacteria or viruses, a biologist can turn relatively harmless virus such as the flu into a deadly virus. If one of these altered viruses is to be released into the public, the consequences could be hundreds of times worse than the plagues that have affected humans throughout history. These viruses are so
