Pollution is a “dirty” word. To pollute means to contaminate —to spoil something by introducing impurities, which make it unfit or unclean to use. Pollution comes in many forms. We see it, smell it, taste it, drink it, and stumble through it. We literally live in and breathe pollution, and, not surprisingly, it is beginning to threaten our health, our happiness, and our very civilization.
Once we thought of pollution as meaning simply smog — the choking, stinging, dirty air that hovers over cities. But air pollution, while it is still the most dangerous, is only one type of contamination among several which attack the most basic life functions.
Through the uncontrolled use of insecticides, man has polluted the land, killing the wildlife. By dumping sewage and chemicals into rivers and lakes, we have contaminated our drinking water. We are polluting the ocean, too, killing the fish and thereby depriving ourselves of an invaluable food supply.
Part of the problem is our exploding population. More and more people produce more wastes. But this problem is intensified by our “throw-away” technology. Each year Americans dispose of 7 million autos, 20 million tons of waste paper plates. It is easier and cheaper to buy a new one and discard the old, even though 95 percent of its parts may still be functioning. Baby’s diapers, which used to be made of reusable cloth, are now paper throwaways. Soon we will wear clothing made of paper: “Wear it once and throw it away” will be the slogan of the fashion conscious.
Where is this all to end? Are we turning the world into a gigantic dump, or is there hope that we can solve the pollution problem? Fortunately, solutions are in sight. A few of them are positively ingenious.

    Do pigeons use their biological clocks to help them find directions from the sun? We can keep pigeons in a room lit only by lamps. And we can program the lighting to produce artificial "days", different from the day outside. After a while we have shifted their clocks. Now we take them far away from home and let them go on a sunny day. Most of them start out as if they know just which way to go, but choose a wrong direction. They have picked a direction that would be correct for the position of the sun and the time of day according to their shifted clocks.
We have talked about one of the more complex experiments that lead to the belief that homing pigeons can tell directions by the sun. But what happens when the sky is darkly overcast by clouds and no one can see where the sun is? Then the pigeons still find their way home. The same experiment has been repeated many times on sunny days and the result was always the same. But on very overcast days clock-shifted pigeons are just as good as normal pigeons in starting out in the right directions. So it seems that pigeons also have some extra sense of direction to use when they cannot see the sun.
    Naturally, people have wondered whether pigeons might have a build-in compass - something that would tell them about the directions of the earth’s magnetic field. One way to test that idea would be to see if a pigeon's sense of direction can be fooled by a magnet attached to its back. With a strong magnet close by, a compass can no longer tell direction.

     Of all the sports that America has to offer, baseball is considered the pastime of this country. Americans did not always regard baseball and other sports in such a benign manner. Rather, sports during the early colonial times were seen as pagan and devilish thing to do. Many elite and wealthy gentry who embodied the Victorian ideals regarded any type of games or sports as ill vices. It was the common people who directly related sports to their religion. On days of religious celebration, early Americans joined together to play games. These folk games were unstructured and unruly; however, the unity that these games brought, created a need for professional sporting games. Folk games provided the foundation of sports. They created a sense of companionship and unison among individuals. These unorganized folk games created the threshold for organized sports and led to the transformation of the players’ roles and the role of the audience. Amateurs became professional athletes, and the game an organized business. The game of baseball evolwed from the English game of cricket and rounders. It was not until the time of the Civil War that baseball began to be played frequently.

    It was a great shock to me to discover that I had motor neuron disease. I had never been very well co-coordinated physically as a child. I was not good at ball games, and my handwriting was the despair of my teachers. Maybe for this reason, I didn't care much for sport or physical activities. But things seemed to change when I went to Oxford, at the age of 17. I took up coxing and rowing. I was not boat race standard, but I got by at the level of inter-college competition.
    In my third year at Oxford, however, I noticed that I seemed to be getting clumsier, and I fell over once or twice for no apparent reason. But it was not until I was at Cambridge, in the following year, that my father noticed, and took me to the family doctor. He referred me to a specialist, and shortly after my 21th birthday, I went into hospital for tests. I was in for two weeks, during which I had a wide variety of tests. They took a muscle sample from my arm, stuck electrodes into me, and injected some radio opaque fluid into my spine, and watched it going up and down with x-rays, as they tilted the bed. After all that, they didn't tell me what I had, except that it was not multiple sclerosis, and that I was an atypical case. I gathered, however, that they expected it to continue to get worse, and that there was nothing they could do, except give me vitamins. I could see that they didn't expect them to have much effect. I didn't feel like asking for more details, because they were obviously bad.
    The realization that I had an incurable disease, that was likely to kill me in a few years, was a bit of a shock. How could something like that happen to me? Why should I be cut off like this? However, while I had been in hospital, I had seen a boy I vaguely knew die of leukemia, in the bed opposite me. It had not been a pretty sight. Clearly there were people who were worse off than me. At least my condition didn't make me feel sick. Whenever I feel inclined to be sorry for myself I remember that boy.

     "Junk food" is difficult to define. White sugar is probably the nearest contender for the title. It contains plenty of calories for energy but not much else, and is often described as an "empty calorie" food. Alcohol is also high in calories, but beer and wine contain some of the B vitamins and wine is a what is a good source of iron, so even a teetotaler could not describe all alcohol as useless, nutritionally speaking. Calories measure the energy we derive from the food we eat, and sugar and alcohol are sometimes described as having a high energy density. There is a limit to the amount of energy we need each day (2,000-2,200 calories is the average for women and 2,500-3,000 for men) and if we eat too much sugar and alcohol there is no appetite left for the vitamin-rich foods we need—fish, meat, fruit and vegetables. Buying vitamins can be predicted by psychological as well as nutritional motives and it is prudent to investigate why we think we need them and what benefits we expect from them before we rush off to the health shop to make our purchases.
    Most of us buy vitamins for one of three reasons. Either we believe that they are prophylactic, that is they will ward off advancing ill, or they are therapeutic and will deal with the ills we have already, or finally we may believe they are wonder drugs and will lift us into a state of super health, with all its attendant delights. We are protected from some of these wild imaginings by the laws which control advertising but even without false promises we still believe that vitamins placebo pill is never underestimated in clinical trials used to test new drugs. A placebo is a harmless substance given to one group of patients in the trial and it is similar in taste and appearance to a new drug which is given to a second group of patients. Theoretically the drug should cure or relieve any symptoms and the placebo should have no effect. Often these trials produce surprising results and the placebo group recovers as well as the group taking the new drug. It is a "mind over matter" philosophy and for some of us it works. Vitamin pills can sometimes fall into this category.
    Vitamins B and C cannot be retained in the body, so if we take more than we need of these, they are soon excreted in the urine. The possible exception here is the theory about the increased body "pool" of vitamin C, but even this is limited and is still largely unproven. Taking too much of the fat soluble vitamins can be dangerous and vitamins A and D should never be taken indiscriminately. Vitamin E has not been found to have any toxic effect in large doses, but neither do there seem to be any noticeable benefits. This is an unexplored area in vitamin research and the only known advantages of vitamin E are confined to specialized medical cases.
