These days，vegetarian food （素食） is very popular in restaurants around the world and many people are vegetarians．Are you one of them？
    About 70% of the world's vegetarians live in India，and about 30% of its population are vegetarians．A lot of these people are Hindus，so religion （宗教） is an important reason why they eat vegetarian food．
    其他人吃素食是为了帮助保护地球． We eat a lot of meat，and to make the space to produce it，we need to cut down trees and plants，and that's bad for the environment．Also，to produce 1 kilo of meat，an animal needs 8 kilos of vegetarian food．It's better for the environment if we don't eat meat．
    Also，some people think it's wrong to eat animals． And some eat vegetarian food because it's healthy．
    For all these reasons，vegetarian food has a better future．Between 3% and 7% of people in the UK are vegetarians，and 86% of its population eat vegetarian food one or two days a week．In Brazil the number of vegetarians is between 5% and 10%．And Ghent City in Belgium is the Vegetarian Capital of the World．It has a vegetarian day．Every Thursday，schools and public service offices serve vegetarian meals to children and adults of all ages．
