[IELTS Ideas] Genetic Engineering

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 human’s genetic characteristics
  • Scientists may use genetic engineering to cure
  • 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 part
  • 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

 

Genetically-Modified (GM) Foods: Advantages

  • 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

 

Genetically-Modified (GM) Foods: Disadvantages

  • There may be risks involved in the genetic engineering of
  • 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 fertilizers or
