Urban ecology is a branch of ecology that focuses on the study of how organisms interact with each other and their environment in urban areas. This field of research examines the ways in which human activities, urbanization, and development impact ecosystems, biodiversity, and ecological processes in cities. Urban ecologists study topics such as urban heat islands, air and water pollution, habitat fragmentation, and the effects of urbanization on wildlife populations. Ultimately, the goal of urban ecology is to understand how to create sustainable and resilient cities that support both human and ecological well-being.
