Big thanks to National Geographic photographer Joel Sartore for his talk last night at Ohio State and to CFAES’s David Hanselmann and his colleagues in the School of Environment and Natural Resources and Environmental Professionals Network for serving as hosts. Some 800 people packed the Ohio Union’s Archie M. Griffin Grand Ballroom. If your interests include wildlife of all kinds and sizes (from veiled chameleons to Francois langurs to Sumatran tigers), photography, and saving Earth’s sadly, ridiculously threatened biodiversity, check out Sartore’s stunning Photo Ark project.
