The Importance of Technology in Health Care

          One of the major aspects of Health Care, like many other things in our society today, is technology.  Technology plays a very important role in many things we do and helps the human race make important advances in the way we do things. For example, without technology in Health Care we would not be able to detect diseases or view organs, bones, or muscles without operating.  To name some technological medical devices, there are:
-          Ultra sound machine ( diagnostic imaging machine used to visualize  internal body structures  like muscles, bones, organs, ect)
-          Electronic thermometers (A thermometer that uses electronic circuitry to detect temperature-induced changes in a thermal element and display the corresponding temperature in a digital form )
-          X-Ray Machine (An X-ray generator is a device used to generate X-rays. These devices are commonly used by radiographers to acquire an x-ray image of the inside of the body)
-          MRI’s (magnetic resonance imaging: the use of nuclear magnetic resonance of protons to produce proton density images)
-          CAT Scan (An X-ray image made using computerized axial tomography)
-          Angiography (Examination by X-ray of blood or lymph vessels, carried out after introduction of a radiopaque substance)
-          ECG (electrocardiography)  (The measurement of electrical activity in the heart and the recording of such activity as a visual trace (on paper or on an oscilloscope screen), using electrodes placed on the skin of the limbs and chest)

      As you know I’m sure, that without technology it would be much more challenging for doctors to detect things like diseases, damaged bones or muscles, or cancers.  Treatments and diagnostics would have to be based on mainly guesswork, judging from only external appearance. Technology such as X-ray machines, MRI’s, CAT scans, and angiographies enable doctors to view a person’s internal organs that make up the circulatory, digestive, and respiratory systems , and detect any abnormalities or dangers. Without these devices we would not be able to detect things such as cancer early enough to provide treatment or comfort. Therefore, technology, as stated above, is a vital aspect of healthcare and people all over the world, including Canadians, have made numerous contributions to this technology. For example, one of the most noted Canadian contributions to health care was in when 1992; Frederick Banting and Charles Best at the University of Toronto discovered a way to treat diabetes (using Insulin).


   
When researching the importance of various technologies involving health I came across an intriguing article about how in December of this year the first MRI diagnostic imaging scanner was installed in Gander, Newfoundland. (http://www.canhealth.com/News1661.html) The article discussed how the “The opening of the MRI suite in Gander will ensure that residents in the central region of the province have access to important diagnostic procedures without having to travel long distances.”  It basically discussed and pointed out how important it is for people to have access to advanced technological health care equipment and how fortunate, we as Canadians are, to have such a good health care system. 
        Overall I believe that everyone can agree, that without technology in health care, we would not have such advanced medical procedures, we wouldn’t be able to detect illnesses or disease in early stages, we wouldn’t be able to search and experiment with cures, and we wouldn’t have the wonderful understanding that we do today of the digestive, respiratory, and circulatory system in the human body!

Differences Matter; Sustainable Over Industrial : A Little Pest Creats A Lot of Damage!


 The lodge pole pine, also known as the Pinus Contorta or Shore Pine, is a common tree in western North America. Like all pines it is an evergreen tree.
The lodge pole pine is a very popular species that humans have numerous uses for.
Today this species is in a very high demand. Because of this high demand the trees are heavily farmed throughout the province of British Colombia. The same species of trees are grown, harvested, and then re-planted.  This is a significant example of Industrial agriculture because it is an industrialized production of this tree (or crop) to meet the high demand of our ever growing population for this specific type of wood. It overlooks the well being and balance of forest ecosystems and completely eliminates the concept of biodiversity.
                Industrial agriculture has many negative consequences. For example, the industrial agriculture of the lodge pole pine has resulted in a lack of biodiversity, and a therefore vulnerability to pests.  The Mountain Pine beetle, also known as the Dendroctonus ponderosae Hopkins has posed as a huge threat to this type of tree. The beetle is about the size of a grain of rice, is dark colored, and lives most of its life in trees. Their lives are shorter than a year and they lay eggs in trees and over time they hinder the tees ability to draw water and nutrients.   Numerous epidemics have occurred over time and this species cause mortality of large numbers of trees. Major outbreaks have occurred in southwestern Alberta in the late 1970s and early 1980s. Outbreaks have also consistently occurred in British Colombia over the last several decades.
The beetles have destroyed millions of pine trees (over 400 square kilometres) leaving once forested areas barren. At the current rate, 80% of mature pine trees in B.C. will be dead by 2013. The Lodge pole pine, B.C.'s most commercially harvested tree, as stated above, has been especially targeted which has led to millions of dollars in losses. The trees are being so dramatically affected because they are all the exact same. There is no diversity and therefore the beetle affects the species of trees in all the same way, which results in enormous epidemics with devastating results.
                                What is the solution to this problem? Simple, it’s Sustainable agriculture over Industrial Agriculture. Sustainable agriculture refers to the ability of a farm to produce product indefinitely, without causing irreversible damage to ecosystem health. Meaning instead of farming and re-farming the exact same tree over and over again for human use, farmers should attempt to plant numerous diverse species in order to maintain balanced ecosystems in forests. This would result in the many unique trees that would most likely be able to resist the negative effects of the mountain pine beetle.
In conclusion, In order to have a prosperous future involving nature and our environment we need to make the correct choice, which is sustainable over industrial.
