How were the pyramids at Giza Constructed - Essay Example The great pyramids consist of huge stone blocks, carefully measured out and carved, and then slotted in to fit a perfect geometric shape on a truly colossal scale. Scientists today are still trying to figure out how a nation without modern lifting equipment and mechanized transportation could possibly have had the technical skill and physical power to construct these tall edifices in the sandy ground. The fact that the Egyptians possessed such a capability is undeniable, since the pyramids are still standing there as evidence. How these people managed this great feat is, however, a deep mystery. It has long been recognized that the ancient Egyptians used ramps and wooden sleds to transport huge blocks of stone from the quarries to the building site, and that there is no evidence that they knew about the wheel, the pulley or the derrick (Dunham, 1956, p. 161). It seems that they just built ramps and used many thousands of workers, and this simple explanation is widely accepted. Another, much more radical theory has been advanced by Danish scholar Erich von Dà ¤niken who argues that it would have taken human beings some 600 years to build the great pyramid of Cheops, the largest of the pyramids at Giza, shifting more two and a half million blocks of stone (Von Dà ¤niken, 1970, p.96) and using tens of thousands of workers at any one time. He theorized that there was insufficient food and shelter for such a number of workmen in the largely desert land around the area, and that therefore the ancient Egyptians must have had help from some supreme god-like beings from outer spac e. Assembling arguments gathered from other massive structures across the planet, and from legends about Egyptian gods such as Ra, who â€Å"travelled through the heavens on a bark† (Von Dà ¤niken, 1970, p. 94), the theory of ancient aliens helping to build the pyramids emerged. The two theories outlined above argue on very different principles. Von Dà ¤niken’s argument is based on vivid

Food safety - Research Paper Example The report of Potter and Hotchkiss stated that, â€Å"food preservation is an action or method designed to maintain foods at a desired level of quality. A number of new preservation techniques are being developed to satisfy current demands of economic preservation and consumer satisfaction in safety, nutritional and sensory aspects† (McElhatton & Marshall,3). Since food is perishable in nature, there is a necessity to preserve the food that we eat through food preservation techniques. The importance of food safety has become the main concern of the consumers worldwide because health issues and several food-related diseases that can go with it. The first thing to consider before dining-out or buying take-away food is to make sure that the food that you are paying for is nutritious and safe. Nowadays, people prefer to dine-out than cook their own meals at home because of their busy lifestyle. Eating out or buying food to take home from food establishments actually saves time and effort of its consumers. In fact, there are several fancy and affordable fast food restaurants which offer great-tasting meals.

Thus, most of the big or small food corporations alike should practice sanitation and cleanliness in preparing food because this concerns the health of the general public which is of utmost concern. Food corporations must be transparent to their consumers on the ways and methods used in preparation of the meals they serve to the general public. Thesis: The proper preparation of food by maintaining cleanliness and good sanitation by the food-producing corporations shall ensure food safety and protect the health of its consumers. II. Ethical Issue and Debates The study of Sherrow and Marzili reported that â€Å"widespread outbreaks of illnesses cause by the food we eat have grabbed headlines, but news reports have been left unanswered. In the US, e verything from snack food made with spice imported from China to spinach grown organically in California has been implicated.

Thus, many Americans suffer from foodborne illnesses due to the passive and unreceptive response of the government agencies to combat this growing problem. Included are the big corporations, engaged in food industry who fail to monitor the safety of the food supply, and sometimes poor hygiene implemented in their food premises. Government agencies such as FDA and USDA must be able to carry-out the objectives of their offices to protect the general public. Food is a basic necessity and human beings are dependent on food for survival. However, the government should regulate the food ma nufacturers, food operators and restaurant owners, by enforcing stricter laws to safeguard the safety of the consumers. III. Corporate Social Responsibility It is the responsibility of food corporations to be transparent when it comes to serving the food that they serve to their consumers. It is
