Impact on the environment
In addition to the medical disadvantages associated with fast food, the production and selling of junk food puts a significant negative impact on the environment. The amount of resources necessary to raise the meat for fast food products creates a shortage of resources around the world. For example, every pound of hamburger we consume takes 2500 gallons of water and 16 pounds of grain to produce, say nothing of the land needed to raise the cattle and the grains to feed them. The animals raised to make fast food meat products are often fed antibiotics and a poor diet that causes the animals to be underdeveloped. These antibiotics and growth hormones can be passed on to those who consume the meat afterward, leading to negative health effects. Some have reported growing extra breast tissue or developing damage to the immune system from eating fast food on a regular basis.
