Should we eat more horse meat? In some parts of the world it is a food taboo, while in others people think little of munching an equine burger. Would it be better for our health and that of the planet if we ate more of it? We’re at a pony auction in the English countryside where some rather hairy creatures are going for a song. Could turning them into sausages and steak be the best way to add value? From there we travel to Paris to find out why the French are losing their taste for horse meat, we find out if it could be more sustainable and healthier than beef, and examine the roots of the world's horse meat taboos.
