Study reveals how Ethiopia's hyenas combat climate change, save money for waste management and prevent disease‎

Urban scavengers like spotted hyenas are preventing more than 1,000 metric tons of carbon emissions annually in Ethiopia's second-largest city, according to new research revealing the predators' role as accidental eco-warriors. By consuming organic waste that would otherwise rot, these predators are saving the city of Mekelle over $100,000 USD in waste management costs while reducing the significant sanitation risk associated with routine roadside dumping.
