Citizen scientists track air and water pollution at fracking sites in windswept Wyoming and five other states, using simple but science-based techniques developed by the "Bucket Brigade." On idyllic East Coast trout streams, volunteers from Trout Unlimited monitor water quality regularly, generating baseline data that will prove invaluable in the event of future pollution events. Community members connected with professional researchers to tackle Flint's drinking water crisis and now the same is happening in Philadelphia and other cities. In China, citizens use government data and a unique mobile app to report environmental crimes. When citizens and scientists partner, it's a win-win for all concerned.
