柏林街头共享冰箱，免费食物减少浪费
In Berlin, some streets have a special surprise. It is a large fridge on the sidewalk. People put food inside for others. The food is free for everyone. This is a community fridge.
The idea is simple and warm. You can leave fresh food you do not need. Bread, fruit, vegetables, and even cooked meals are welcome. Then, anyone can open the door and take it. No one asks for money.
