With more of us becoming more conscious of our health and the environment, vegans and vegetarians look set to make up a quarter of the British population in 2025.

But for those who haven’t completely committed to the cause there’s the national Veganuary campaign. Last year 250,000 people signed up, dedicating themselves to a month of no meat and dairy products for a mixture of health, environmental and ethical reasons. But does the food trend really have an impact on the way we live?

We spoke to Gala Bailey-Barker, a farmer in Sussex, who believes that knowing where your food comes from is more important than the diet you choose. Dale Vince explains why he decided to take over and transform Forest Green Rovers into the world’s first vegan football club. And the BBC’s environment correspondent Matt McGrath explains whether one month of no meat and no dairy can really help save the planet.
