The University of Sheffield-led study reveals urban scavengers such as spotted hyenas, African wolves and vultures are providing a vital ecosystem service by consuming waste that, left to rot, releases greenhouse gases and spreads disease. "Animals like spotted hyenas have adapted to a high-density, urban environment and have become an essential part of the city's ecosystem. This generates 1,240.6 metric tonnes of meat waste - the equivalent to the total weight of roughly 31,000 live sheep. Having established hyenas and other scavengers' value to the city, the research team is now turning its attention to the animals themselves.
