“Between 1950 and 2006, the WWF report notes, the world’s annual fishing haul more than quadrupled, from 19 million tons to 87 million tons. New technology — from deep-sea trawling to long-lining — has helped the fishing industry harvest areas that were once inaccessible. But the growth of intensive fishing also means that larger and larger swaths of the ocean are in danger of being depleted.”

In late July, formal and non-formal educators joined @nature_indiana, @indianadnr Division of Nature Preserves, and @lakecountyparks for a workshop exploring ecological restoration in the Grand Calumet River Area of Concern.
Participants toured restored sites in East Chicago and Hammond, engaged with experts in sediment remediation and habitat restoration, and experienced a cutting-edge Virtual Reality curriculum aligned with NGSS for grades 6–12.
From industrial past to ecological renewal, educators left inspired and equipped to bring local environmental stories into their classrooms.
