[One Thousand Characters a Day] The Imagination of Genetic Engineering Becomes Reality <3>

Editor's NoteGenetic engineering technology, which is gaining attention as a means to overcome humanity's challenges such as incurable diseases, aging, and food shortages, cannot exclude discussions on ethical issues and side effects. Is it acceptable for parents to decide the genes of their unborn child? Are genetically modified organisms (GMOs) truly safe? Although answers to these questions have yet to be found, continuous discussion and regulation must be carried out as technological advancement cannot be stopped. For example, although many people avoid GMOs, 30% of the seeds traded in the global market are already genetically modified. Therefore, instead of avoiding GMOs, we should be able to develop safer GMOs through meticulous regulation. Word count: 1035 characters.

Meanwhile, genetic engineering technology, as a science that deals with life, involves philosophical discussions. Some argue that correcting innate genomes goes against the laws of nature. Regardless of whether it was created by God or is a product of chance, the question is whether it is justifiable for genetic engineers to alter the essence of living beings by removing defects or maximizing advantages in livestock and crops with the purpose of enriching and improving human life, much like engineers repairing broken machines and replacing parts.

However, the genome that humans possess is inherently constantly changing. This is why biological evolution has been possible. All living organisms, including humans, continue to exist alongside the constant changes in their genomes. Gene therapy is also one method of altering the genome.

Since ancient times, humanity has continuously applied curiosity and a spirit of inquiry to solve problems and pursue progress rather than remaining stagnant. Efforts to solve infectious disease problems threatening humanity have resulted in longer lifespans, and as lifestyle changes increased metabolic diseases, methods to address these were also found. Aging, memory decline, and lack of flexibility, once accepted as natural phenomena in the elderly, are now recognized as issues to be resolved for a healthy life, broadening the scope of medicine.

With the completion of the Human Genome Project and the beginning of the 21st century, a much deeper understanding of medicine and the human body has emerged, predicting the era of personalized medicine. For example, instead of saying "a certain drug will cure a cold with a certain probability after a certain period," it will be possible to predict "if drug C, which best matches your genes, is administered, your current symptoms will disappear within a week."

As knowledge of life sciences increases, more fundamental questions may arise. However, in the process of seeking answers to these issues, humanity will extend healthy lifespans, enable happier lives, and improve welfare. Science will develop with the help of humanities and social sciences to create a better society.
