Michael John Hudak is an environmental researcher and author, Sierra Club activist, radio broadcaster, and public speaker concerned with the environmental damage (and harm to free-living animals, or wildlife) that ranching inflicts on US public land (mostly in the Western states).
He is an author of Western Turf Wars: The Politics of Public Lands Ranching (which focuses on grazing issues) and its companion series of web-based videos.
In 1999, he founded the nonprofit Public Lands Without Livestock.Hudak's grassroots educational outreach on "public lands grazing” addressed thousands of Sierrans (Sierra Club members) and others.
His photos and written explanations clearly picture the ecological problems of continuing livestock production on public lands.
