A camp built by students and volunteers spreads over Southern Methodist University（SMU）. The affordable  21  are designed to be used by the poor as well as survivors of war and natural disasters.
“By the time 2020, there’s going to be about 1.7 billion people living in slums（贫民窟） so we would like to  22  change,” says Stephanie Hunt, co-founder of the Hunt Institute for Engineering and Humanities at SMU. The institute, which  23  build the village on SMU’s campus, was established to solve problem of the poor in the United States and around the world through engineering, and the free  24 .
The goal is not just to  25  lives, but to change the victims’ lives. The Institute hopes some entrepreneurs（企业家） might program and  26  some money with these ideas. One of the structures in the SMU village was built with bricks made  27  from recycled plastic bags.
They’re  28  together with heavy wires. Harvey Lacey, father of two college-aged sons, including one here at SUM, heard about this project and  29  his invention. It’s a heavy-duty, hand-crank pactor（手动压缩机）that anybody can use to form the big bricks he calls Ubuntu Blox.
“The advantages are that these  30  weigh less than two pounds. They’re very, very  31  These things can go for many generations of housing, ”says Lacey, who is  32  the design. Anybody can follow his online plans to  33  the pactor that turns plastic bags into bricks.
On this warm day, it’s  34  inside the Ubuntu Blox hut, thanks  35  to the thick plastic insulation（绝缘）. Kenyan  36  Ronald Omyonga, visiting the global village before returning to his native Africa, says his country is full of these recyclable bags. With Lacey’s design, he says that litter could be transformed into  37  housing. He dreams of other  38  too.
“Look at the Harvey Lacey hut, as a means of creating  39  ,”says Omyonga.“Leaning the environment, and turning  40  into something that can form houses, not just for the poor.”
