Why is genetic engineering a source of controversy?

Answer 1

While some people might fear genetic engineering because it is impossible to know what effects modifying genes will have in the long-term, because their religious convictions cause them to believe that modifying what God made will bring about bad results, or for other reasons, not all who oppose genetic engineering do so because of fear. Some believe it is simply common sense not to mix genes of different species together like is done with the genetic modification of crops. Some have even discovered results of research that suggests genetic engineered crops are causing negative effects on the environment, so there are genuine concerns that are not based on fear that need to be seriously considered.
