Our colleague, Dr. Mourad Gabriel, is the subject of a recent feature article by bioGraphic, a part of the California Academy of Sciences. Dr. Gabriel is the executive director of the non-profit Integral Ecology Research Center (IERC), and is affiliated with the Wildlife Health Center at the University of California, Davis. He has been a leading voice in sounding the alarm over the environmental impacts of marijuana cultivation, and he actively assists law enforcement in studying and remediating illegal marijuana grow sites. This article provides a very good overview of the environmental harms of marijuana, and of Dr. Gabriel’s work.
