Human hair being used to clean Rio's Guanabara Bay in Brazil
In an innovative and eco-friendly grassroots initiative, environmentalists and volunteers are utilizing recycled human hair to combat severe pollution in Rio de Janeiro's iconic Guanabara Bay. Because natural hair is remarkably efficient at absorbing oils, greases, and organic contaminants, local cleanup campaigns are packing hair donations into nylon stockings to create low-cost, highly effective booms.
