Genetic Engineering: The Ethical Dilemma for Investors

Genetic engineering, also known as genetic modification, involves directly manipulating an organism's DNA to alter its characteristics in a specific way. This technology has revolutionised fields like medicine, agriculture, and biotechnology by enabling the creation of organisms with desired traits. However, it also raises significant ethical, societal, and environmental concerns that influence investor decisions.

What is Genetic Engineering?

Genetic engineering involves the insertion, deletion, or modification of genes within an organism's genome using biotechnology. Techniques such as CRISPR-Cas9 allow for precise gene editing, which can result in beneficial traits like disease resistance in plants, enhanced nutritional content in food, or the elimination of genetic disorders in humans (Livescience).

For example, genetically modified crops like Bt corn have been engineered to produce a toxin that repels pests, reducing the need for chemical pesticides (Genetic Literacy Project). In medicine, genetic engineering has paved the way for therapies like CAR-T cell therapy for cancer treatment, where a patient's T cells are modified to target and kill cancer cells (National Cancer Institute).

Positive Impacts of Genetic Engineering

1. Agricultural Benefits: Genetically modified (GM) crops can offer increased yield, improved resistance to pests and diseases, and tolerance to environmental stressors like drought and salinity (NIH). This can lead to more sustainable farming practices and food security in regions prone to harsh agricultural conditions.

2. Medical Advancements: Gene technology is providing breakthroughs in human health that were previously impossible. Some of the uses of genetically modified organisms (GMOs) in human health include producing vaccines or medicines, developing diagnostic tests, treating genetic diseases using gene therapy, and developing targeted therapies for diseases such as cancer (National Gene Technology Scheme). 

3. Environmental Benefits: GM crops that require fewer chemical inputs can reduce the environmental impact of agriculture. For example, plants engineered to fix nitrogen more efficiently could decrease the need for nitrogen fertilisers, which are a major source of greenhouse gas emissions (The Breakthrough Institute).

Negative Impacts of Genetic Engineering

1. Ethical Concerns: Genetic engineering raises numerous ethical issues, particularly concerning human genetic modification. The Nuffield Council on Bioethics has published the findings of an in-depth inquiry into the ethical issues arising from heritable genome editing interventions in humans. It has concluded that the use of heritable genome editing interventions to influence the characteristics of future generations could be ethically acceptable in some circumstances, provided it is intended to secure, and is consistent with, the welfare of a person who may be born as a consequence of interventions using genome-edited cells, and it upholds principles of social justice and solidarity, ensuring it does not increase disadvantage, discrimination, or division in society (Nuffield Council on Bioethics).

2. Environmental Risks: The release of GM organisms into the environment could have unforeseen ecological consequences. GM crops may cross breed with closely related plants (Royal Society). As there is the potential for GM crops to crossbreed with wild relatives, leading to the spread of modified genes in wild populations.

3. Societal and Economic Issues: The adoption of GM crops can lead to economic disparities, particularly for small-scale farmers who may not afford the technology or the seeds. Developing countries, particularly small-scale farmers, are cited as losers in this situation, as the industry directs its production to capital-strong buyers, namely large farmers in the Global North (International Journal of Environmental Research and Public Health).

Ethical Investment Considerations

Given these complexities, some investors choose to avoid genetic engineering on ethical grounds. Ethical investing involves considering the moral and social implications of investments, beyond just financial returns. Investors may avoid genetic engineering due to concerns about:

• Biodiversity and Ecosystem Health: The potential long-term impacts on biodiversity and ecosystem stability are significant. Ethical investors may prefer to support agricultural practices that promote sustainability and ecological balance.
• Human Rights and Equity: The ethical implications of genetic modification in humans, such as the potential for eugenics and inequality, can be a deterrent for socially conscious investors.
• Corporate Practices: The concentration of power among biotech companies that control genetically modified seeds can lead to unethical business practices, such as exploitation of farmers and unfair patenting practices.

For these reasons, ethical investors might opt for alternatives that align with their values, such as supporting organic farming, renewable energy, and healthcare solutions that do not involve genetic modification.

Conclusion

Genetic engineering is a powerful tool with the potential to bring about significant benefits in agriculture, medicine, and environmental sustainability. However, it also poses ethical, societal, and environmental challenges that must be carefully considered. For investors, the decision to support or avoid genetic engineering depends on a complex interplay of potential benefits, risks, and ethical considerations. By staying informed and considering the broader impacts of their investments, investors can make choices that align with both their financial goals and their values.
