Executive Summary DNA engineering, whether it be related toà food and humans, has been aà controversialà topic in 21stà century. Since the first identification of genes in the mid-1800s,à scientistsà have come very far. DNA, known as deoxyribonucleic acid, is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of almost all known forms of life. Scientists have been able to map the DNA sequences of people as an indication of the individual.à à Sequencing technology has beenà provenà usefulà inà many aspects. In this article, six subtopics will be discussedà includingà geneticallyà modified organisms (GMOs), invasion of privacy, incurable diseases, eugenics and denial of choice, cloning,à and overpopulation. Gene modifications in the food industry led to better yields and pest resistance, but also raised the issues of safety and morality. Furthermore, gene editing could also be appliedà to humans. Individuals could spendà aà reasonable amount of money to sequence their genome to identifyà aà potential disease. Researchà centersà also collect DNA samples to do medical researches about inherent disease. However, with the outside access towards an individualââ¬â¢s biological information, the issue of the protection of privacy is raised.à With modifying genomes inside ofà humans andà foodà toà treat inherent diseases and increase food yield, another problem arises: overpopulation. Sinc e the typical limiting factor of population growth is resources,à genetic technology would be a powerful tool to resolve theà foodà and energy limitations.à This report will have six sections includingà all six distinctiveà subtopics. Within each of these sections, technical issues, ethical issues, and possible recommendations will be discussed.à à The main technological advantage of DNA engineering is that it could reveal the biological information of people.à Scientistsà couldà not onlyà identifyà genomic makeup,à butà they could also modify the sequence ofà genesà which means they could change a certain individualââ¬â¢s biological identification, like a predisposition to a curable illness. A technical issue of DNA engineering inà theà food industry is that there may be possible health risks associated with GMOs. To improve yield of crops and other agricultural products, scientistsà inserted new genes into plants through bacterial plasmids to provide advantageous genetic traits. A plasmid is a small DNA molecule, which can carry foreign genesà within a cell that is physicallyà separated from a chromosomal DNA and can replicate independently. The GMOs largely increased food yields and farmer profits, however, many suggest that GMOs have health risksà including food allergies, antibiotic-resistant bacteria, and farmerââ¬â¢s property rights. For humans, DNA engineeringà may yield to experimentation with and subsequent health risks associated with cloning. Scientists can clone organsà using CRISPRà byà injecting human stem cells into pig embryos. However, it may resultà inà genomicà endogenous retrovirusesà which is a robust immune system barrier. The immune systemà ofà anà individual mayà recognize the organ as foreign and would subsequently attack it.à à As DNA engineering has the potential to cureà diseases,à extendà oneââ¬â¢s lifespan, andà increase the yield of agriculturalà productsà through GMOs, overpopulation may start to become an issue. Overpopulation can result in water shortage, land shortage, decrease of quality of life and other environmental problems.à à The ethical issues within the topic of DNA engineering is extensive. Economic controversy may occur when it comes to GMOs. Farmers may end up inà aà dilemma: either being forced to pay higher pricesà for the engineered seeds of crops because science corporations have the patent, or being uncompetitive in the market because they have less yield of products.à à DNA engineering also raises the issue of privacy. In recent years, DNA has gone from an academic research activity to a governmental commercial enterprise. When DNA samples are taken,à they are subsequently stored, allowing the chance of unauthorized access toà an individual's personal information consisting of entirely whoà theyà are.â⬠¯ As a fetusââ¬â¢s genome is explored (without consent), the DNA testing may reveal potential incurable diseaseà when sequenced. Individuals may go to the hospital to screen for a flu but end up finding out that he is predisposed to an incurable disease. Telling a patient of a future, incurable illness that they may or may not suffer through is a tricky ethical question. It may violate the moral autonomy of the ignorant patient, yet hearing the news may cause excessive anxiety, depression, and hopelessness to a patient. With the current ethical issues surroundingà DNA engineering, four main recomme...
