Put down your hamburgers! This week we are tucking into the topic of sustainable diets, looking at the many, many environmental impacts of the food industry and finding out why many of us are moving to vegan, vegetarian or flexitarian diets.

We’re looking at the future of food security in a growing world, the carbon emissions and water demands of different food-producing practices, nifty new farming and agriculture technologies, and whether or not that all means we all have to turn 100% vegan.
