The new technique of genetic engineering presents problems on many levels. Scientists can now create plants, animals, and even microorganism by manipulating their genes in an unnatural way. Genetically modified organisms (GMO) can spread throughout nature and interbreed with natural organisms, which can lead to unpredictable futures. The release of GMOs into the environment is known as "genetic pollution" and causes future threats to our environment since GMOs cannot be recalled once they are in the environment. This causes a moral issue as some people believe that since GMOs are a new invention, they should not be released into the environment, especially because there is not sufficient scientific understanding on how these modified organisms will affect the health of humans and our environment (Green Peace).
Genetic engineers hope to profit by patenting genetically engineered seeds.Most genetically modified crops today have been designed to improve farming, but when a farmer plants these seeds, all the seeds have identical genetic structure. This can lead to widespread crop failure if a fungus, virus or pest develops and attacks the particular crop.
Genetically engineered foods have caused the deaths of thirty seven people and caused 1,500 to be partially paralyzed. 5,000 more people were temporarily disabled by a syndrome that was finally linked to Tryptophan made by genetically engineered bacteria.
Genetic engineering raises many ethical problems. Some of these problems include cloning. The first type of cloning was exhibited by Dolly in 1996. The death of Dolly in 2003 posed many questions about the safety of genetic engineering and cloning.
