Current Public Heath Issues - Essay Example This disease in a healthy, productive work force of the country is a major problem for the government, as it has to spend increasing amounts of funds on their treatment and care, while earning hands have decreased. For the past four decades, there was an encouraging decline in the spread and attack of CVD (Heart Disease May Be On The Upswing 2008), which led to the hope that there was finally a check on it, and still a chance for recovery from this problem. However, this hopeful trend lasted just till 1995 (Heart Disease May Be On The Upswing 2008). ... Discussion: in this study carried out on 425 people in Minnesota, US, who had died of unnatural causes, researchers found shocking evidence that CVD is on the rise again, and this time it is affecting a lot of young population as well. This study was published in the Archives of Internal Medicine (Heart Disease Might Be On The Upswing 2008) in early February 2008, and explored the trends and the causes behind this upsurge. The age group of the cases under study ranged from 16 to 64. What was surprising was that out of the younger cases, 8.2% had high-grade heart disease, and 83 percent had clogged arteries, marking a beginning of coronary artery disease, which puts them at a risk of developing major heart problems as they age (Heart Disease May Be On The Upswing 2008). Researchers are yet trying to establish firm causes of this upswing of CVD, especially among the younger population. They are especially not sure how and to what extent do obesity and diabetes play a role in increasing the occurrence of CVD among young people. However, they have confirmed that recent trends and changes in the lifestyles of the people are the major causes of this rise. There has been an increase in the sedentary lifestyle of people, owing to the introduction and the spread of computers, which has led to a decline in their physical exercise (Heart Disease May Be On The Upswing 2008), and computer related activities like playing games and working solely on computers, such as typing jobs.

Geology Questions. Sustainable development and resource management - Essay Example Hubbert did not base his predication on feelings or emotions, he used a formula. He could prove what he was saying. It is looking like Hubbert was the only smart one that could face reality. 3. Many hydrothermal mineral deposits of copper, gold, silver, and other metals have been found in the countries bordering the Pacific Ocean. Can you offer an explanation for this remarkable concentration? If you were part of a team of exploration geologists looking for large copper deposits, where would you focus your search? Mineral deposits of copper, gold, silver, and other metals or ores are found in areas where the Earth’s crust has been pushed up or made by plate tectonics. Just like oil and coal are made by pressure in the earth. The ore is created by pressure in the crust. The Pacific Ocean has deep faults and plate tectonics pushing at the crust. For example, the earthquakes in California does not just cause destruction. It also causes ores to be created and pushed to the surface . If I was part of a team of exploration geologists looking for large copper deposits, I would look in plate eruptions on the ocean floor near magmatic arcs. 4. Given that we are now dependent on nonrenewable resources of energy and minerals, and that the world's population continues to increase, how do you think human societies will adjust in the future? Do we have a resource problem or a population problem (or both)? Human societies will have to learn to depend on renewable sources. If this is not possible, extinction would be a possibility. In order to survive humans will have to live off of renewable energy like wind, water, and other renewable sources. I do not believe humans will develop renewable resources until forced to.... Main questions of this article are: Oil production in the United States satisfies only half of the country's needs; the rest is imported. If imports were cut off, what changes would you expect to occur in your lifestyle? Investigate how geophysicist M. King Hubbert predicted in 1956 that annual U.S. oil production would peak in the early 1970s (the actual peak occurred in 1971). Also, investigate the debate over whether the same predictive technique can be applied to world oil supplies. When do you think world oil production will reach its peak—or has it done so already? Many hydrothermal mineral deposits of copper, gold, silver, and other metals have been found in the countries bordering the Pacific Ocean. Can you offer an explanation for this remarkable concentration? If you were part of a team of exploration geologists looking for large copper deposits, where would you focus your search? Given that we are now dependent on nonrenewable resources of energy and minerals, and that the world's population continues to increase, how do you think human societies will adjust in the future? Do we have a resource problem or a population problem (or both)? Some people think that sustainable development is not a useful concept, because it may be impossible to implement—or even to define—in the case of nonrenewable resources. Others think that it is an extremely important concept, if only because it makes us think about the needs of future generations in planning resource management. What do you think?
