"ing at CHEJ, I had an incomplete understanding of environmental justice. I pictured the field solely as activists and victims opposing corporate polluters. Although I understood that research supports these organizing efforts, I never considered methods that scientists adopt to evaluate ecological data. One of these methods is GIS (geographic information systems), a computer program designed to collect, analyze, and distribute spatial data. GIS specialists create maps to interpret data across various disciplines. When appropriate techniques are applied, GIS can help solve geographically-related problems."
