More and more city dwellers are collecting food in the asphalt jungle. They harvest herbs by the roadside and grow wild vegetables in cracks in the concrete. For these modern foragers and hunters, the food is free, tasty and more varied than in the supermarket. Christian Amys is an urban foraging professional. He forages for fresh food in his hometown of Brighton. For him, the English coastal city is an urban Garden of Eden. Christian finds wild vegetables and herbs in places where most people would never expect to find food. The 42-year-old only spends a few pounds a week on food from the supermarket: "I want to be independent and don't like to rely on the supermarket. I like to forage on my doorstep because it's nice to know where my food comes from."
