John F. Kennedy, rocket designer Wernher von Braun, and astronomer Carl Sagan were alive today, I think that we would probably be walking on Mars by now. I hope space exploration still stirs Americans to press on. Let’s keep the dream alive and walk on Mars! RICK SCHREINER San Marino, California Necessary Angels The article was an inspiring story born of necessity. There are just not enough doctors and nurses to provide curative care. In the developed world we will have to move to the preventative model the story describes because we cannot afford our current health systems. But unlike the workers in India’s Comprehensive Rural Health Project, who are trained to provide care and advice, the caregivers must be our- selves. We currently eat too much of the wrong foods, smoke and drink too much, take too many legal and illegal drugs, and don’t exercise enough. When we can’t ﬁnd a doctor willing to prescribe antibiotics for what we think is wrong, we ﬁnd one who will. Doctors and other health workers must be prepared to “prescribe” healthy living rather than tablets for every- thing. Maybe then we will not run out of money. JOHN R. ERREY Garmisch-Partenkirchen, Germany Environment: Trash Register You point out that “drink cans accumulate unless a state has deposit laws.” This seems only partially true. I live in Oregon, which has a ﬁve-cent deposit on cans and bottles, yet I am still amazed by the number I see discarded along the road. I enjoy biking the back roads. Several days a month, instead of taking a training ride on my street bike, I ride my modiﬁed mountain bike and pick up all the cans and bottles I encoun- ter. Over the course of four rides, I collected over 600 cans and bottles. My sister-in-law, who lives in Michigan, points out that their ten-cent deposit has proved to be a major deterrent in the battle against littering. Maybe all states should implement a ten-cent can and bottle deposit. FRED TAFT Corvallis, Oregon Clean naturally. Introducing Nature's SourceTM Natural Bathroom Cleaner.
