The arguments for and against genetic engineering are varied. Proponents of genetic engineering cite the multitude of medical technologies which can arise out of these endeavors. If scientists can find and modify the genes for certain diseases like cancer, they could potentially cure those diseases by preventing or amplifying the expression of certain genes. It is speculated that with genetic
. modification, scientists can one day regrow limbs that have been lost, and repair medical conditions such as paralysis. This may present a candid approach, especially when there exist ethical issues with other procedures to treat these conditions, such as stem cell research.The arguments against genetic engineering are equally compelling. Most of the fear comes from the thought that it is playing God to mess with something as basic as life itself. Many people fail to realize the scope of damages that can arise from the improper modification of an organism's genome. Unlike a chemical contamination, such as an oil spill, which dissipates over time, a biological contamination is self-replicating. A genetically modified organism that is accidentally released into the environment can cause catastrophic consequences to the natural environment, affecting all trophic levels of the ecological pyramid. This is why a great deal of consumers prefer to only purchase organically grown food products. GMO plants are created by splicing genes from completely unrelated species in the hope that the expression of such genes will cause the plant to develop resistances to highly toxic pesticides and insects. As history has shown, this is not always the case. The potential for genetic engineering brings great promise, but science and technology must be at a suitable level for these undertakings. It is for this reason most people are opposed to the prospect of genetic engineering.
