Why is urban sprawl a concern for environmentalists?

Urban sprawl is a concern for environmentalists because it often leads to the destruction of natural habitats and ecosystems, resulting in biodiversity loss. It typically increases reliance on automobiles, contributing to higher greenhouse gas emissions and air pollution. Additionally, sprawl can strain infrastructure and resources, leading to issues such as water pollution and increased energy consumption. Overall, the unchecked expansion of urban areas can undermine sustainable development and exacerbate climate change impacts.
