Providing food and shelter to victims of a natural disaster is one of the first priorities for emergency services, but the process can often generate a lot of unnecessary waste. To help tackle this problem, UNICEF has developed an amazing reusable LEGO-inspired brick that doubles as a food storage container and a building material, addressing multiple needs in one fell swoop. The bricks have two compartments – one that holds rice and another that holds water. Once these vitals have been consumed, the bricks are then filled up with soil and sand to give them weight and stacked just like lego bricks into temporary shelters that gives disaster victims relief from the elements. In the meantime, all of the packaging that might have been used to provide clean drinking water and food are spared, as well as the headache of sourcing and distributing them. And the best part? When this area recovers, the bricks can be re-used somewhere else!
