I propose all human beings be allocated a 10x10 meter concrete apartment (15x15 if living with a partner, and 20x20 if you are permitted to have children).

Furthermore, everyone will be given a standard monthly food ration consisting of rice, dry beans and powdered milk.

Each resident can own up to 3 "luxury" items selected from a standard catalog.

Each resident is permitted to travel no more than 150 miles from their residence each month, and personal cars are banned.

Imagine how quickly we could heal the environment if everyone could agree to these common sense restrictions!
