People become vegetarian for different reasons. Some adopt a vegetarian diet as the ethical alternative to eating meat, because they believe killing animals is wrong. People who are concerned about their health see it as a good way to keep slim and lower their risk of various diseases. Lately, more people are replacing meat with vegetables because of the vital role this plays in protecting the environment.
Researchers from the Union of Concerned Scientists in the U.S. released a report on the impact of consumer behavior on the environment. Their study showed that meat consumption is one of the main ways that humans can damage the environment, second only to the use of motor vehicles.
