Art installation built from waste materials displayed in Vancouver

People look at an art installation that built from wasted construction materials at a street in downtown Vancouver, Canada, Dec. 9, 2017. Created by New Delhi-based artist Asim Waqif, the art installation "Salvage" is built by the materials collected from landfills generated from construction sites in metro Vancouver. The artist wants to raise the concern of the environment and social responsibility in better using waste as a resource rather than going to landfills. (Xinhua/Liang Sen)
