BRUNSWICK  — The Nature Conservancy in Maine is using Earth Day to launch a fundraising campaign to protect the state’s lands and waters.

The “Sustainable Maine, Sustainable Planet” campaign is an effort to raise $100 million to help conserve areas stretching from Moosehead Lake to Washington County, and from the Gulf of Maine to Mount Agamenticus and beyond.

Projects include helping the Gulf of Maine regain its status as one of the most productive marine ecosystems; restoring a river system via the Penobscot River Restoration Project; finalizing the Moosehead Forest Project to protect more than 400,000 acres in western Maine; providing opportunities for urban youth to experience conservation work in the state; and others.
