When I look back at 1970 later in life, as an amateur environmental historian, I can fully appreciate what happened that year. It wasn’t just April 22—the first celebration of Earth Day—it was 12 months of successful citizen work to raise consciousness and pass new federal and state laws that revolutionized America’s treatment of air, water, land, fish, and wildlife. Michigan was a national leader on the environment throughout 1970. Every time I think of Michigan in 1970, I am deeply grateful to the many largely unsung citizens who pressured elected officials to conserve and protect the environment. We owe them a great debt for reforms that persist today.
