The manufacture of vehicles is resource intensive, and many manufacturers now report on the environmental performance of their factories, including energy usage, waste and water consumption.[43] The growth in popularity of the car allowed cities to sprawl, therefore encouraging more travel by car resulting in inactivity and obesity, which in turn can lead to increased risk of a variety of diseases.[44][dead link] Transportation (of all types including trucks, buses and cars) is a major contributor to air pollution in most industrialised nations. According to the American Surface Transportation Policy Project nearly half of all Americans are breathing unhealthy air. Their study showed air quality in dozens of metropolitan areas has worsened over the last decade.[45] Animals and plants are often negatively impacted by automobiles via habitat destruction and pollution. Over the lifetime of the average automobile the "loss of habitat potential" may be over 50,000 square meters (540,000 sq ft) based on primary production correlations.[46] Animals are also killed every year on roads by automobiles, referred to as Roadkill. More recent road developments are including significant environmental mitigations in their designs such as green bridges to allow wildlife crossings, and creating wildlife corridors. Growth in the popularity of vehicles and commuting has led to traffic congestion. Brussels was considered Europe's most congested city in 2011 according to TomTom.[47] |
