A leading animal advocacy group says the road to Mideast peace begins in a pita. The People for the Ethical Treatment of Animals has requested Israel's permission to post pro-vegetarian signs on both sides of its barriers with the West Bank and the Gaza Strip. PETA's signs are in Hebrew and in English. They feature Israelis and Palestinians sitting down for a meat-free meal along with the slogans: "Give Peas a Chance," and "Nonviolence Begins on Our Plates: Go Vegetarian." "Every time that we eat, we can choose not to participate in violence," PETA President Ingrid E. Newkirk wrote Wednesday in a letter. "While choosing a falafel sandwich over a lamb kebab doesn't create instant peace, it reduces the sum total of violence and suffering in the world."
