Firstly I want to tell you that scientists developed many useful and great things by genetic research, for instance the manipulation of food. It holds longer and doesn’t get bad so far. The genetic manipulated apples are also bigger and less vermiculated (worms in it) than the normal grown apples.
Apart from that there are also dangers included. With gene manipulation we could set cruel things into the world, like more painful and destroying weapons for senseless wars.
Do you know the story about “Frankenstein”? I think that this could be come true. Scientists could create monsters and mutants that will kill us, without their will.
Another risk is also that plants could be overspread and suck the whole water from the world, so everyone has to die.
So, my opinion is that we have to be very careful and never underestimate the danger of experimenting with genetics. The consequences would be too much and horrible. But I’ll still eat genetic manipulated apples, because they taste better.
