How a #Litterati army on Instagram sparked a global fight against litter

What started as a small group of people taking pictures of waste in their communities and tagging it on Instagram with the hashtag #Litterati, turned into a global effort, and even an app, to map and dispose of trash. Users can upload to the app an image of trash and machine-learning algorithm can tag it location, material, and company who made it. The city of San Francisco asked the makers of the app for help documenting cigarette butts and tobacco products on its streets and ended up winning a legal victory over the tobacco industry to increase the taxes on their products.
