If you haven’t heard of genetically modified humans, perhaps you’ve heard the media banging on about ‘designer babies’. They do exist but the science behind genetically modified humans isn’t as crazy and horrific as people make it out to be and can cure hereditary diseases in many cases.
It is a Controversial Subject
The topic of genetically modified humans, called germ-line engineering is cause for massive debate. There are about 40 countries in the world that have banned the practise of it, or at least see it as highly unfavourable and do nothing to help the science advance. It is a fairly new type of science and so everyone needs to fully understand it and voice their opinion, the issue is when the media calls it things like ‘designer babies’, making it seem like people are going to create some robot like child that looks exactly how they want.
It Could Massively Decrease Risks of Hereditary Diseases
Germ-line engineering could help to eradicate genetic disorders. Ovarian Breast cancer is one horrific illness that is caused by a mutated gene. If this mutated gene was in an egg or sperm cell, then why not a attempt to replace it with a normal, unmutated gene. Scientists figured out how to use bacteria to help replace a segment of DNA with a healthy one.
Doing this to an egg or sperm cell would ensure than no genes in the offspring would be mutated, and so pose no threat, it would also mean that any future children of this offspring wouldn’t be at risk either, so could in theory eradicate diseases from our societies forever.
