At a time when we need inspiring stories more than ever, we're announcing our 2024 Sierra Club Wisconsin Award winners! We'll highlight stories like the 'David and Goliath' fight the City of Superior took on (and won!) to protect Lake Superior and a nearby cemetery from Dairyland's proposed gas plant and uplift like high schoolers coming together to host walk-puts and lobby legislators demanding climate action.
