Julia has just returned home to her parents from university in London where she is studying her degree in eco-health.

Tomorrow is her mother’s 60th birthday and she’s planning to cook a meal for all the family. She opens up her meal planner app and asks it to update the quantities for seven, taking into account her sister’s gluten intolerance, her brother’s love of Italian and her grandparents’ MIND diet – designed to prevent dementia and loss of brain function as you age.

She smiles gleefully at the thought of showing her dad that the entirely vegan meal has surpassed daily recommended nutrition guidelines. Secretly he would prefer to eat steak, but she’s determined that the whole family follow a more flexitarian 1 diet . The app alerts her that the order has been placed at the local supermarket, and will be ready for collection at 1pm. At the supermarket, Julia makes her way to the pick-up point through the vegetable area. Micro greens are lapping up the LED light and water softly dripping across the hydroponic shelving stack growing leafy vegetables all year round.
