M.A.D. (Meat And Dairy)

Abstaining from meat one day a week is, according to Ghent councillor Tom Balthazar, “good for the climate, your health and your taste buds”. Indeed, the UN says meat and dairy production account for 18 per cent of greenhouse gases – more than the world’s entire transport system – and the amount of carbon saved by turning vegetarian for a year is, says the Vegan Society in Australia, equal to switching from a normal car to a hybrid for 12 months.
