BiomeViewer, an interactive app from HHMI BioInteractive, is designed to engage students in three-dimensional learning as they explore the phenomenon of human impact on biodiversity and the environment. BiomeViewer contains data about biomes, anthromes (anthropogenic biomes), precipitation, and temperature. When students select anthromes, they can see how humans have changed the environment over time from 1700-2000. Students may also select a location on the globe and receive a description, climate data (downloadable on Apple devices), wildlife information (mammals, amphibians, and reptiles), and references for further information. Comparisons can be made between two selected locations. BiomeViewer also includes educator materials.
