Google lends its machine-learning tool to fight deforestation

Google's machine-learning tool is being used to detect and combat illegal deforestation The news: Rainforest Connection, a San Francisco nonprofit, has developed a cheap, rigorous acoustic monitoring system made from modified cell phones and solar panels. An app on the so-called Guardian devices, which can be hidden in trees throughout forests, continuously listens for the telltale signs of illegal logging and animal poaching. On March 21, the organization announced that it will be using Google's TensorFlow, a free tool that makes it simpler for other companies and groups to develop machine-learning software (see "Google stakes its future on a piece of software"). Rainforest Connection says it will enable the organization to more accurately detect troubling sounds in the uploaded audio, such as chainsaws, vehicles, and gunshots. Deforestation reduces biodiversity, increases erosion, and promotes desertification.
