Urban ecology, also known as city ecology, is a field of study that explores the relationships between organisms, humans, and their physical and social environments in urban areas. Other synonyms for urban ecology include urban biology, urban environmental science, urban sustainability, and urban biodiversity. These terms highlight the importance of understanding how cities impact the natural world and the need for sustainable urban development. As more and more people move into urban areas, it is increasingly vital to study and create solutions for the complex ecological challenges facing cities. Through urban ecology research and implementation, cities can become livable and healthy environments for both people and wildlife.
