Litterati is a community that’s “crowdsource-cleaning” the planet, one piece of litter at a time. What started with one person picking up a single cigarette, has grown into a worldwide movement in 100+ countries. The Litterati mobile app is used to connect the community and collect data — information that is used to demand corporate accountability, inform government policy, and inspire each of us to protect the planet. Litterati has partnered with the National Science Foundation, the United Nations, and was recently highlighted at TED.
