There's less than a month to go before the Olympics kick off in Paris. It's a big event for athletes but also for chefs, who are getting ready to serve over 40,000 meals per day. As part of a pledge to limit greenhouse gas emissions, the Paris Games are set to make history by offering more vegetarian cuisine than any previous edition. The committee says the event's plant-based offering will help halve the carbon footprint of meals, compared to the Rio and London games. Our team at Down to Earth got to have a taste.
