Applying ecological principles to urban planning is significant for creating sustainable cities that can accommodate growing populations while minimizing environmental impact. Principles such as green infrastructure, biodiversity conservation, and resource-efficient designs promote ecological health within urban areas. These strategies improve air and water quality, enhance urban habitats for wildlife, and increase resilience to climate change. Moreover, incorporating ecological insights allows urban planners to design spaces that prioritize human well-being, through access to green spaces and reduced heat islands. Thus, embracing ecology in urban planning fosters sustainable, livable communities that nurture both people and the environment.
