Positives of Genetic Engineering

  • Genetic engineering is the practice of manipulating the genes of an organism.
  • It is used to produce crops that are more resistant to insects and diseases.
  • Some genetically modified crops grow more quickly.
  • Some drugs and vaccines are produced by genetic engineering.
  • It may become possible to change humans’ genetic characteristics.
  • Scientists may use genetic engineering to cure diseases.
  • Inherited illnesses would no longer exist.
  • Genes could be changed before a baby is born.
  • It could also be possible to clone human organs.
  • We could all have replacement body parts.
  • Humans could live longer, healthier lives.

Negatives of Genetic Engineering

  • There are ethical concerns about human genetic engineering.
  • Parents might want to choose their children’s characteristics.
  • This would be unnatural.
  • It would be unacceptable in most religions.
  • Soldiers could be cloned from the genes of the strongest people.
  • Clones might be used like robots to do certain jobs.
  • Clones might even be developed just for organ replacements.
  • Society and human evolution would change completely.
  • Currently, human genetic engineering is prohibited.

Advantages of Genetically-Modified (GM) Foods

  • Farmers can produce crops that grow bigger and faster.
  • Some GM crops are more resistant to disease or insects.
  • This could be important for food production in developing countries.
  • Faster growing cereals, fruit and vegetables will mean more profit.
  • GM foods can be modified to look perfect.
  • They may be more attractive to customers.

Disadvantages of Genetically-Modified (GM) Foods

  • There may be risks involved in the genetic engineering of foods.
  • GM crops might change whole ecosystems.
  • Food chains could be broken if crops are resistant to predators.
  • Organic foods are produced without chemicals or genetic modification.
  • Organic farming may be slower and more expensive.
  • However, the environment is not damaged by fertilisers or pesticides.
