Climate change: Cars are a major source of greenhouse gases, which trap heat in the atmosphere and contribute to climate change. The transportation sector is responsible for about a quarter of all U.S. greenhouse gas emissions.
Water pollution: Cars can pollute water sources through stormwater runoff and oil leaks. Stormwater runoff from roads and parking lots can carry pollutants such as sediment, heavy metals, and pesticides into waterways. Oil leaks from cars can contaminate groundwater and surface water.
Land pollution: Cars can pollute land through the extraction and processing of raw materials, the construction of roads and parking lots, and the disposal of old cars. The mining of metals and minerals for car production can damage ecosystems and pollute the air and water. The construction of roads and parking lots can lead to deforestation, habitat loss, and soil erosion. The disposal of old cars can contaminate soil and groundwater with heavy metals and other toxic chemicals.
Noise pollution: Cars can generate a lot of noise, which can be disruptive to people and wildlife. Noise pollution from cars can also contribute to stress, anxiety, and sleep problems.
Traffic congestion: Cars can contribute to traffic congestion, which can waste time, fuel, and money. Traffic congestion can also lead to air pollution, noise pollution, and stress.
Accidents: Cars can be involved in accidents, which can cause injuries and death. Car accidents can also damage property and cause traffic congestion.
