9. 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 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 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
