What are some pros and cons of genetically altering human DNA?
PRO: Genetically engineered foods are usually “substantially equivalent” to other foods, with no increased risk to human health, and no need for the lengthy and expensive human testing demanded of, for example, new food additives. CON: The unpredictable disruptions in normal DNA functioning caused by genetic engineering can produce unanticipated and unknown side effects for human health, including unknown and unpredictable toxins and allergens, and these possibilities can only be definitively assessed through human testing.
