(Fast food facts-internet) Eating disorders associated with a sedentary lifestyle contributes to obesity, and obesity is expensive. As an example most of the diseases above-mentioned are directly related to obesity. Realize that it is still possible to eat fast food occasionally and follow sensible diet.

             Fast food also contributes polluting the environment. Just think that for a second how much garbage do fast food restaurants throw away every day. It is a lot. And where it comes from? This is an easy question. It comes from every wrapped burger, straw, or chips and drinks containers. Just imagine thousands of burgers, hot dogs, sandwiches and so on are sold every day in United States, so a lot of garbage is collected every day, but just a small part of it is recycled. .

             Another reason of why fast food pollutes the environment is beef. In the United States beef is king. The Western World has a love affair with beef. But how many people are aware that the real costs of the cattle culture are animal suffering, global hunger and poverty, and environmental devastation. More than 6.7 billion-hamburgers were sold last year at fast food restaurants. Beef has been central to the American experience. The relationship between beef and the environment pollution is that cattle raising is a primary factor in the destruction of the world's remaining tropical rain forests. They graze on nearly 24 percent of landmass of the planet and consume enough grain to feed hundreds of millions of people. The burning of tropical forests to clear land for pasture releases millions of tons of carbon dioxide into the atmosphere each year. There are currently 1.28 billion cattle populating the Earth. Cattle are also a major cause of global warming.(Rifkin) They emit methane, a potent global warming gas, blocking heat from escaping the Earth's atmosphere.

             One more reason is our dependence on animals for food and the profoundly inhumane and unhealthy conditions under they are currently raised.
