After four years of collecting water samples, we are confident that our dataset represents the most diverse and one of the largest datasets exposing the extent of microplastic pollution around the globe. With this in hand, we have transitioned to data analysis as we seek a deeper understanding of microplastic pollution, and importantly, how our work can contribute to positive change. This data has already inspired businesses to reduce their plastic consumption, is being used by governments towards conservation decision making, and has motivated over 80% of our project volunteers into taking action towards reducing plastic pollution.
