Litterati: Can a digital landfill rid the world of litter?

A resounding yes comes from the community of Litterati, an app that asks users to identify, photograph and geotag individual pieces of trash before disposing of them.

It's a simple enough idea: crowdsourcing data that could help stop litter from being created in the first place.

So far, Litterati has cataloged over 750,000 pieces of litter from 114 countries, with hundreds being added every day.
