Although they were invented almost a hundred years ago, for decades cars were only owned by the rich. Since the 60s and 70s they have become increasingly affordable, and now most families in developed nations, and a growing number in developing countries, own a car. While cars have undoubted advantages, of which their convenience is the most apparent, they have significant drawbacks, most notably pollution and traffic problems. The most striking advantage of the car is its convenience. When travelling long distance, there may be only one choice of bus or train per day, which may be at an unsuitable time. The car, however, allows people to travel at any time they wish, and to almost any destination they choose. Despite this advantage, cars have many significant disadvantages, the most importantof which is the pollution they cause. Almost all cars run either on petrol or diesel fuel, both of which are fossil fuels. Burning these fuels causes the car to emit serious pollutants, such as carbon dioxide, carbon monoxide, and nitrous oxide. Not only are these gases harmful for health, causing respiratory disease and other illnesses, they also contribute to global warming, an increasing problem in the modern world. According to the Union of Concerned Scientists (2013), transportation in the US accounts for 30% of all carbon dioxide production in that country, with 60% of these emissions coming from cars and small trucks. In short, pollution is a major drawbackof cars.
