"Food for Free" is a concept that encourages people to gather and consume food that is available in nature without cost. This can include foraging for wild fruits, nuts, and edible plants, as well as collecting surplus food from gardens or farms. The practice promotes sustainability and helps reduce food waste. The idea is often associated with the movement led by individuals like John Kallas, who advocate for foraging as a way to connect with nature and understand local ecosystems. By learning about edible plants and their habitats, people can enjoy nutritious food while fostering a sense of community and environmental stewardship.
