Ghost Food: With the help of a wearable smell-dispensing device and an edible textural analogue, GhostFood truck customers will experience a simulation of a future phantom food. It might sound a little snobbish, but the idea is to offer “a simulation of how you might experience that food once it’s no longer available." The three items on offer are cod, chocolate, and peanut butter. Although the artists behind Ghost Food don't have a climate change agenda, the backstories are there. Chocolate, for example, is already suffering supply shifts and shortages as a result of climate change: "Drought, pest and disease increases, and the changing temperature of the topsoil all make cacao trees harder to grow and their harvests smaller. [...] In West Africa, the source of half the world’s chocolate, there’s an additional wrinkle: the growing regions will need to migrate upwards in elevation to stay productive, which means more deforestation, which then further exacerbates climate change." It's a fascinating mix: the sensation of trying out the ghost foods, while realising how unsustainable our ways of harvesting these foods is.
