Plastic pollution is a global epidemic that requires innovative solutions. Although plastic pollution has a significant & permanent impact on the marine environment, where plastic is entering the oceans, how it moves across space and time or what impact this has on biodiversity or human health is largely unknown. Data and funding to address this global epidemic is basically non-existent however we are at a turning point as never before was it possible to involve huge numbers of people in data collection. To incentivize the most rapid production of global open data the world has ever seen, OpenLitterMap applies blockchain proof-of-work mining principles to the production of geographic information for the first time and rewards users with Littercoin for doing the work of citizen science. What impact this has on policy, public expenditure or legal accountability has yet to be determined but the data is open and you are needed to become a pioneer.
