For thousands of years we have bred animals and selected crops to improve our food production. We did it by altering the genetic make-up of our domestic animals and farm crops by artificial selection. This is no different. When we alter the DNA of an organism directly, it is the same thing only more efficient. After all, God gave us the minds and the ability to discover the genetic basis of life.
Customers have the right to know what is in their food.
Hence they have the right to have genetically modified foods clearly marked so that they can avoid them if they choose. This is important not only as a courtesy for customers but is essential for the health and well being of some customers who have allergies. They need to know if there is a potential hazard if a gene from one organism has been shifted into their food. The FDA labeling regulations do not apply to normal crops and domestic animals. They only set up guidelines to deal with brand new manufactured products to ensure safety.
