Final answer:
The problem of cars and cities contributes to pollution, traffic congestion, and resource depletion. Alan Durning proposes solutions such as promoting public transportation and compact urban development.
Step-by-step explanation:
The problem of cars and cities reflects the nature of environmental problems by contributing to pollution, traffic congestion, and the depletion of natural resources. Cars emit greenhouse gases and pollutants that contribute to air pollution and climate change. They also require the construction of roads and parking lots, leading to deforestation and habitat destruction. Alan Durning, an environmental activist and writer, has proposed solutions such as promoting public transportation, implementing bike lanes and pedestrian-friendly infrastructure, and advocating for compact urban development to reduce the dependence on cars and mitigate the environmental impact.
