Dairy
A genetically engineered growth hormone called rBGH (recombinant
bovine growth hormone), is given to dairy cows which causes them to produce up
to 15% more milk than they naturally do. The natural milk production of the average dairy cow was almost 5,300 pounds of milk a year and today it is more than 20,000 pounds. It also increases growth. These extra hormones that are produced are thought to be contributing to cancer, early puberty in girls, and several other health problems in humans. Studies show that about 17% of all US cows are given rBGH to make them grow unnaturally faster. Other methods of forcing greater milk production are selective breeding, feeding grain-based diets, and leaving the cows in artificial light for long periods of time.
