California nonprofit organization, Cardborigami, has created a simple solution to a complex problem. Inspired by origami principles of construction and folding, Tina Hovsepian designed a temporary homeless shelter that is constructed out of cardboard. The biodegradable and recyclable structure is both water-resistant and flame-retardant. Shelters can be constructed by two people in just a half hour. Once constructed, it is easily collapsible and transportable.
