Urban foraging teaches us many things. “We learn about plants, botany, and ecology, as well as how people can participate positively in interacting with their local ecosystems,” says Wildman. In New York City, “local ecosystem” is a slippery term. Parks mix with projects that mix with residential homes that mix with corporate buildings. It’s hard to think of brick and mortar as part of the local ecosystem. That’s precisely urban foraging’s power. It alters our perception and our connection to the land.
