"First Do No Harm" is a video resource designed to educate health care professionals and others about the industry's contribution of dioxins to the environment. It was produced by the Western Lake Superior Sanitation District (WLSSD) as part of an ongoing Zero Discharge Project whose goal is to reduce the discharge of persistent bioaccumulative toxic substances in the Lake Superior Basin. Health Care Without Harm financed copying of the video and is assisting in its distribution.
