Different risks would be associated with genetically engineered animals, like easier disease transmission or increased rate of cancer in animals

How can fetuses or animals consent to the modifications which might be possible on them?

Modification can only be tested on live subjects

Transgenic crops could bring new allergens into foods that sensitive individuals would not know to avoid.

There is a risk in all genetic modification of rejection and incompatibility, which often leads to the death of the subjects or irreversible harm

Reversible

Possible with current technologies

Addition of foreign genes to plants could also have serious consequences for wildlife in a number of circumstances

Patients can give consent

More infrastructure

Better education and medical assistance

There is no way to research without being intrusive

Many subjects required, which have no guarantee of living
