Jeff Kirschner When his 4-year old daughter saw a plastic tub of cat litter in the woods, little did Jeff Kirschner realize that it would be the spark for creating Litterati – a worldwide movement that’s “crowdsource-cleaning” the planet one piece of litter at a time. Featured by National Geographic, Time Magazine, and Fast Company, Jeff has spoken at Fortune 500 companies such as Google, Facebook, and eBay, keynoted environmental summits at the Monterey Bay Aquarium and Smithsonian, as well as leading universities including Stanford, Berkeley, MIT, and the University of Michigan. Jeff was recently a TED Resident where he built Litterati into an “idea worth spreading.”
