I believe that human genetic modification should be allowed. My main argument is that using genetic modification to improve the quality of human life is an effective use of scientific progress. Humanity can finally conquer such incurable diseases as cancer, aids, and cystic fibrosis through genetic engineering in medicine (Fernandes, 2021). This applies not only to adults but also to children. The modification of human embryonic DNA offers hope that gene mutations can be corrected and diseases prevented from being passed on (Blair, 2019). In the future, such procedures may result in children no longer being born with cystic fibrosis or with genes that increase the risk of cancer.
As for the genetic modification of animals and insects, it can also be beneficial. For example, thanks to CRISPR technology, modifying the gene responsible for carrying malaria in a mosquito could potentially eradicate the disease forever (Kahn, 2016). This is quite an encouraging statement, considering that many people, including children, are dying from malaria. However, this technology must have an apparent scope of application. The ecosystem of our planet is a fine-tuned mechanism in which all components are closely interconnected. Too much change or removal of one of them can have a catastrophic effect on the environment. Therefore, the genetic modification of animals and insects should be applied judiciously and carefully coordinated with environmental organizations.
In the case of humans, there must also be clear boundaries for modification. Genome adjustment for the purpose of curing a fatal disease or disability is entirely acceptable. However, this kind of intervention should be made only if other therapies are unsuccessful. In addition, I would not permit modification to change external parameters, such as eye color, hair color, or body shape. This technology should only be used in medical practice. Accordingly, only certified specialists in genetics and biology should have access to it. In addition, before being allowed to work with CRISPR, testing must be carried out to see whether the person is aware of what he or she is working with. In this way, genetic engineering will serve the good of humanity and cannot harm anyone.
