A good point. But if we have the power to do so, why not do it?
So why can't we alter them in an easier way? Lab-type mutation is pretty much a speedier way of selective breeding and hybridization.
A valid pont, but who's to say that something in unnecessary or wrong?
There is a reason that scientists in most universities are required to take ethics classes. The easiest way to describe it, is the basis for the original Jurassic Park movie. Just because science has the ability to clone or create a genetic mutation, does not make it a good idea or ethical. Genetically mutating something (not talking about selective breeding as that doesn't fundamentally alter the creature's DNA) is not something that I think is a moral activity.
I do not have a problem with geneticists and virologists studying DNA and altering DNA and RNA to create vaccines and attempt to eliminate some illness is a good thing. However, altering the DNA of a complex organism for purely aesthetic reasons is wrong, even if it deters people from the hobby.
