Disaster Relief Housing

Disaster relief housing is an important issue.  As seen in my uploaded picture, when a disaster strikes many people are left without homes.  During this time it is important for people to have a place to stay to weather nights, and survive during the reconstruction process.  The housing should last as long as needed, but not last forever, thus is should be made of materials that can be recycled or returned to the earth when their use has come to an end.
Hopefully architects will be able to design a sustainable solution for the inevitable disasters in our future.
