A journalist sits inside an Ecological Living Module, a 22-square-meter "tiny house", at the United Nations headquarters in New York, July 16, 2018. Developed by UN Environment and Yale University in collaboration with UN Habitat, the new eco-housing module is made to spark public discussion and new ideas on how sustainable design can provide decent, affordable housing while limiting the overuse of natural resources and climate change.
