Ghent is introducing a weekly "veggie" day in canteens serving the city's schoolchildren and public service employees. Thursdays will now feature a meat-free dish as the default option on their menus, while new city maps highlight the dozens of vegetarian restaurants in the city.Reducing meat consumption, say the initiators of the scheme, will decrease greenhouse gas emissions. Famous chefs have also been recruited to promote the idea - although it may be an uphill struggle in this traditionally meat-loving part of the world.
