TED: Your empty wine bottle could help rebuild coastlines | Franziska Trautmann

The video discusses the severe coastal erosion in Louisiana and the innovative glass recycling project initiated by two college students. Despite skepticism, they pursued their idea, converting glass waste into sand for restoration projects. The project grew significantly, diverting millions of pounds of glass from landfills and restoring wetlands. The key to their success was starting small and persisting, emphasizing that individual actions can lead to significant environmental change.
