This challenge is seen with some of the first approved gene therapies, which can cost millions of dollars per treatment, putting them out of reach for most people globally.
4. Environmental Impact and Unintended Consequences
Biotechnology extends beyond human health to agriculture and the environment. Genetically modified organisms (GMOs), for instance, have been a long-standing subject of debate:
- Ecological Disruption
- Biodiversity
Could genetically engineered organisms (e. g. , modified crops, gene-edited insects) escape into the wild and disrupt ecosystems in unforeseen ways?
Over-reliance on a few genetically modified strains could reduce agricultural biodiversity, making food systems more vulnerable to disease or pests.
The controlled release of gene-edited mosquitoes to combat malaria, while promising, also necessitates rigorous ethical review of potential ecological side effects.
5. Defining Humanity and Identity
As biotech blurs the lines between human, animal. machine, it prompts fundamental philosophical questions:
- Human-Animal Chimeras
- Neuro-technologies
The creation of organisms containing cells from two or more species (e. g. , human cells in animal embryos for organ growth) raises questions about moral status and identity.
Brain-computer interfaces could enhance cognitive abilities but also raise concerns about mental privacy, autonomy. who controls our thoughts.
These complex dilemmas highlight that the ethical implications of biotechnology are not just about safety. about our values, our future. what it means to be human.
