Activists get technical in a story by Wayt Gibbs for Anthropocene magazine. Low-cost instruments and abundant ingenuity are democratizing surveillance, Wayt writes. The examples are brilliant: crowdsourcing the identification and location of fracking ponds with volunteers who scan aerial images. Repurposing Android phones to detect illegal logging. Using satellite technology to catch unregulated fishing boats. Wayt has more stories queued up for Anthropocene, coming soon. @WaytGibbs image: Markus B├╝rkle
