The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illnesses because of the food that is characteristic in these cultures.That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.1. How has science done a disservice to mankind?2.

The international significance of sliding downhill struck Americans like an avalanche about fifty years ago. Until then, snow had been something to be shoveled out of driveways in the morning. Then the Winter Olympics of 1932 were held at Lake Placid, New York, and a wonderful suicidal new would be opened up.City dwellers read of strange and stirring deeds: bobsledders missing a turn and being scraped off the ice, skiers flying through the air to land on their skulls. The coach of the American team stated that the Winter Olympics were the biggest boost that skiing had ever had; that they should awaken American boys and girls to the possibilities of this wonderful, healthful sport. He was right—in the years that followed, three or four million American boys and girls strapped on skis, and the healthy snapping of bones was heard from Vermont to Colorado.In February of 1960 the Winter Olympics returned to the United States, this time to remote Squaw Valley, California, in Sierra Nevada; where there had been only a lodge and two ski lifts, visitors found that a tiny metropolis had been developed. Early in the preceding December, everything was ready—except the snow. An agitated call was sent out for Piute Indians to dance for the weather gods.“Snow fall in two weeks,” announced the chief when the ceremony was finished.“Why not earlier, chief?”“No chains for our bus,” he said, “Snow too soon, we not get home.”1.
