About 367,000 American children are vegetarians, according to a new study by the federal Centers for Disease Control and Prevention. And the number is reportedly rising. Part of the rise is cause by videos on YouTube that show cruelty to animals on farms, and young viewers choosing vegetarianism based on that awareness. The 1 in 200 figure, which represents .5% of the child population, counts all minors, but older teen vegetarian rates "could be four to six times" that percentage.
