Michael Healy goes inside Bastoy Prison in Norway, the world's first eco-prison and one which has been attracting a lot of attention from around the world. Everything in the prison is eco-friendly. The island facility holds 115 prisoners, including murderers and rapists. They live in houses, are not locked in and are responsible for the care of about 200 chickens, eight horses, 40 sheep and 20 cows. They also tend the fields, pick berries and fish on the prison's 30-foot boat. All very good asks Michael, but does it work?
