The Arrels Foundation is an entity in Barcelona, Spain that has focused on ending homelessness in the city since 1987. They believe in a "staircase" model, which essentially is a philosophy where homeless people need to move "through the phases" to reach a stable living environment. So a person would need to establish roots in temporary housing first, and then, eventually, they could find long-term housing. Support is provided to the individuals at each step of their journey. Each time this video is shared and watched by a new viewer beyond the 30-second mark, the Arrels Foundation makes money from the companies that advertise along the edges of the page.
