Human genome editing: potential seeds of conflict

Recently, The Lancet published an important declaration regarding the necessity of regulating and legislating for human genome editing. We agree with their opinions that the human genome editing technology and resulting research can have both positive and negative effects on human society. The use of genome editing for research and commercial purposes has sparked debates in both biological and political realms. However, most of them have mainly focused on the effects of human genome editing on the patients themselves, and little attention has been paid to their offspring.

Several films, such as Gattaca and Gundam SEED, have addressed the conflicts that arise from human genome editing. Such conflicts not only exist within the generation who have experienced editing but are also transmitted to their offspring. For example, in these films, the offspring of people without genome editing felt a sense of unfairness regarding the inferiority of their physical (or other non-edited domains) status, whereas the offspring of people with genome editing grew up in a biased, discriminated against, and ostracized environment. They could have lived in peace with a strong and well regulated government; however, when the tenuous grip of government weakens, jealousy and resentment can lead to ruins. Although these scenes still exist in films, they might become increasingly plausible in decades to come. Using the concept of preparedness, access, countermeasures, tools, and trust, we should prepare legitimate human genome editing, establish access to deal with imminent or potential discrimination, develop countermeasures and tools for prevention and resolution of conflict, and entrust future generations with the responsibility to use them wisely.

ICEBERG A68a

   An enormous iceberg that is heading toward the island of South Georgia in the southern Atlantic Ocean has broken up into three large chunks. Scientists from NASA have been tracking the berg - dubbed A68a - for several weeks. It actually calved from the Larsen C ice shelf in 2017 and has been floating northwards ever since. In recent weeks, a fast-moving stream of water known as the Southern Antarctic Circumpolar Current Front has put the chunks on a trajectory that means they could run aground off the coast of South Georgia. Scientists say the three fragments are roughly 2,600 square kilometres in size. The submerged part of one chunk is 106 metres at its thickest point.

   The sheer bulk of the three iceberg chunks poses a serious threat to the wildlife of South Georgia. There could be an environmental catastrophe waiting to happen. If the three mini icebergs collide with the seabed, they could obstruct penguins and seals from foraging for fish. They could also block the route between penguin colonies and their feeding grounds during the breeding season. Scientists worry the underside of the fragments could grind the seabed near South Georgia and disrupt delicate underwater ecosystems. This could be exacerbated by the introduction of a mass of fresh water to the ecosystems as the stationary fragments melt over the summer months.
