Trees and other green plants are nature's tools for sucking CO2 out of the air, but scientists say there aren't nearly enough trees to remove all the waste gas we've put into the atmosphere. So some are trying to create new devices that work like trees — like these "pine-tree looking pieces" of fabric being developed by researcher Klaus Lackner at the Center for Negative Carbon Emissions at Arizona State University.
