Take bananas, I mentioned them before as being open to extinction due to a lack of genetic diversity. Most livestock is the same way, it's part of the reason why Mad Cow and Hoof&Mouth diseases spread so quickly in the cattle population.

Let's say Cattle, Pigs, Goats, and a large vareity of popular fruits all go extinct. How much world starvation and suffering would that lead to? How many deaths? Genetic Engineering can prevent that. And don't forget the numerous genetic diseases that plague millions upon millions of humans.

As isntar said, Genetic Engineering isn't some boogymen that can be used to scare people one way or another.
