stop eating everything then. Everything (meat diary plant) has been genetically engineered through selective breeding for thousands of years. Only thing that has changed is our understanding and methods of infecting genes really. All of the food you think of today as 'normal' didn't exist a couple thousand years ago they were created by man! O NO!
Pretty sure breeding never crossed the species barrier much. Here tomato plant, fuck this fish so you get more omega 3s!!
