Activists are using this week’s 9th anniversary of the Kalamazoo River oil spill to dramatize their opposition to a proposed oil pipeline tunnel beneath the Straits of Mackinac.

New research from the University of Michigan shows a lack of transparency when it comes to demographic data within environmental organizations.

This comes from a study of more than 12,000 environmental organizations around the country, ranging in size. The researchers say historically, these kinds of organizations have lacked racial diversity, and little information has been made available to the public regarding the demographic composition of these organizations.
