For travelers stuck at home, the world is a wonder to contemplate—alas from afar. But one of the key goals of sustainable travel—to eat local with a mitigated environmental impact—might not require much more than a walk around the block.
Urban foraging is an intimate study and interaction with the living world around us, singling out a flower or a berry, learning its name and properties, what it tastes like, when and where it grows, how to cook with it or preserve it.
With scientists estimating that we’ll need to feed two billion more people by 2050, the question of which diet is best has taken on new urgency. The foods we choose to eat in the coming decades will have dramatic consequences for the planet.
Instead of looking to futuristic solutions, we might try looking to the past. Before agriculture was established, foraging helped feed our ancestors and heal their ailments. As a result, researchers are increasing efforts to learn what they can about foraging cultures, such as the Tsimane in the Amazon and the Hadza in Tanzania, before this way of life disappears.
