Ethical Concerns

Although recombinant DNA technology can be hugely beneficial, there are concerns raised by environmentalists and anti-globalisation activists in opposition to the use of recombinant DNA technology.

Spread of genes

  • Genetically modified (GM) crops and livestock are produced when a beneficial gene is inserted into their genome to improve a certain trait.
  • The genes could be transferred into other organisms where it is harmful.
    • E.g. A gene for herbicide resistance could be passed on to a weed, or a gene for antibiotic resistance to pathogenic bacteria.
  • Genes from genetically engineered (transgenic) crops could also spread to organic crops.

Unforeseen impacts

  • Genetic modifications to an organism could have unforeseen effects and disrupt normal gene function.
  • The use of genetically engineered organisms could lead to a reduction in the variety in populations.
    • If variety in a population decreases, biodiversity also decreases.
    • Low biodiversity can have negative impacts (e.g. extinction is more likely).
  • GM crops can also produce allergies.

Economic consequences

  • There could be economic consequences for some countries if genetically engineered crops can be grown in different countries where previously it was not possible.
  • Companies who are able to invest more money in recombinant DNA technology may out-compete others.
