People who choose to be vegetarian usually cite the numerous health benefits of the diet as the reason for their choice. Commercially-raised livestock are pumped full of hormones and drugs, and outbreaks of e-coli contamination and mad cow disease happen all the time. You can avoid all of these problems just by making a simple choice not to eat meat products.
If planned properly, there can be no other healthy alternative menu to meat and animal products than a vegetarian diet. Many folks consume meat just because it has always been a part of their lives. They have never thought about replacing the meat they eat with other delicious choices. All people should be able to pick eating habits that they consider the healthiest, and vegetarianism is the right option for many people.
Still other vegetarian people say that they eat the way they do because they object to the inhumane treatment of the animals. The meat production process in this country is truly barbaric, especially when you consider how advanced our culture is in other ways. The production of meat is a horrific process, one that would make even the most enthusiastic meat-eater think twice about what he is eating. The thing is, many people just don't know what goes into the process of getting the meat they eat each day.
People who love animals do not feel that animals should be exploited for the production of meat. These people feel that animals are sentient creatures that do not deserve to be treated inhumanely and killed so that people can eat them. It is possible to maintain health by eating things other than animals.
Many people believe further that the human animal is not meant to be carnivorous. They feel that if the design of our teeth and internal digestive system were looked at closely we would discover that we are designed to be herbivores only.
Another reasons cited for vegetarianism is environmental concerns. There is so much hype and concern over global warming these days, yet most people are completely ignorant of how cattle farms are negatively impacting the situation. Millions of cattle are bred specifically for producing meat. All the carbon in Earth's stratosphere is largely due to cows, for they are huge producers of carbon. If you are really serious about wanting to do your part to safeguard the future of the Earth's environment, then choosing to go vegetarian is the most important lifestyle change you can make.
