Health and Environment
Regular walking is important both for human health and for the natural environment. Frequent exercise such as walking tends to reduce the chance of obesity and related medical problems. In contrast, using a car for short trips tends to contribute both to obesity and via vehicle emissions to climate change: internal combustion engines are more inefficient and highly polluting during their first minutes of operation (engine cold start). General availability of public transportation encourages walking, as it will not, in most cases, take one directly to one's destination.

Famous quotes containing the words health and, health and/or environment:
“The debt was the most sacred obligation incurred during the war. It was by no means the largest in amount. We do not haggle with those who lent us money. We should not with those who gave health and blood and life. If doors are opened to fraud, contrive to close them. But don’t deny the obligation, or scold at its performance.”
—Rutherford Birchard Hayes (1822–1893)
“It is unconscionable that we ration health care by the ability to pay.... your heart breaks. Health care should be a given.”
—Kathryn Anastos (b. 1950)
“People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.”
—William Faulkner (1897–1962)
