GM foods could contain new allergens for people.

There is concern that genetic engineering could lead to the desire for “designer babies” whereby parents can choose their future children’s traits.

GM crops can be herbicide resistant, so weeds can easily be killed without harming the crop

We can make larger, better quality, and faster growing crops and farm animals

GM crop genes could spread into the wild plant population, causing ecological imbalances, e.g. infertility genes.

Genetic engineering could be used to cure genetic diseases like cystic fibrosis & Huntington’s

GM food could be used to deliver vaccines at a lower cost than current vaccinations

Some people think the health effects of eating GM food have not been tested long-term.

Opinion: Genetically modifying mosquitos to produce a protein that kills offspring during the larvae stage.

Opinion: Genetically modifying human embryos that would have a genetic disorder, e.g. Huntington's to give them healthy alleles instead.

Opinion: Genetically modifying tiger embryos to no longer have sharp claws or teeth so that they can be kept as domestic pets.
