“Reasons for Hope,” a new documentary film by Jane Goodall, one of the world’s leading conservationists, highlights projects that are protecting and enhancing the Earth’s environment. Among endeavors Goodall reports on are those led by Klaus Lackner, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, and founding director of  the Center for Negative Carbon Emissions. The documentary focuses on Lackner’s pioneering technology to remove carbon dioxide from air to help clean up the atmosphere and to store carbon underground to be used to support plant growth in greenhouses.
