 In 2000 a Michigan state park lake was polluted by a runoff, and the Hennings were blamed for blowing the whistle on a local Concentrated animal feeding operation (CAFO).Although this accusation was false, it inspired Henning for her work and led to the formation of the Environmentally Concerned Citizens of South Central Michigan (ECCSCM) with other neighbors.Henning and the ECCSCM began to bring the CAFO to justice and urged state and federal agencies to step forward and protect the environmental and public health of region.
