When it comes to enhancing or altering characteristics, the implications can extend far beyond healthcare, impacting ideas about perfection and human diversity.
Many voices in the discussion, including those from the deaf community, argue against the notion of needing to ‘fix’ natural variations in humanity. The worry is that overstepping parental discretion in genetic traits could reinforce societal pressures towards homogeneity at the expense of acknowledging human diversity. This highlights the need for inclusive conversations that consider all perspectives before making decisions about genetic modifications.
Health Justice Implications of Gene Editing
Health equity is a vital consideration in the conversation about gene editing. Innovations in gene technology, while promising, must ensure that they do not exacerbate existing disparities in healthcare access. Baer’s discussion around innovation making the privileged ‘have more’ emphasizes the necessity of integrating health justice into the gene editing narrative, advocating systems that ensure fair distribution of treatment options.
Ensuring equitable access to breakthroughs like CRISPR is critical. Strategies must be devised to protect marginalized populations from being left behind in the gene editing revolution. Ensuring that everyone has access to the benefits of scientific advancements will ultimately lead to a healthier society and mitigate the risks of widening health gaps.
