When I think of technology, I think of the future and how technology progresses more and more as time goes by. But then I think of all the negative affects it has on us and we now depend on it, today kids in grade four have cellphones, I didn't get one till the summer of grade eight. But have you ever thought of how useful technology is and how much it has helped us today? Technology runs in the veins of society.
When it comes to medicine, technology plays a big role. Technology in medicine has made operations easier and faster, it's helped in the understanding, diagnosis and treatment of diseases. Technology; in the form of instruments, devices, machines, drugs, and systems; has aided medical science, altered medical practice, and changed the illness experience of patients. There are many different types of medical machines today, with all kinds of functions. Examples are: -The X-ray, discovered in 1895 by german scientist Wilhelm Rontgen. The X-ray is used to see your bones and primarily to check for bone fractures. -The electrocardiograph, invented in 1903 by Willem Einthoven. The electrocardiograph works mostly by detecting and amplifying the tiny electrical changes on the skin that are caused when the heart muscle "depolarizes" during each heart beat. -The endoscope, invented by Basil Hirschowitz in 1956. An endoscope is a device with a light attached that is used to look inside a body cavity or organ. -The ultrasound scan, invented by the English physician Ian Donald in 1958. Ultrasound scans are used to take images of the internal organs created from sound waves. Ultrasound scanning is used to help monitor and diagnose conditions in many parts of the body, including the kidneys, the liver and the heart. - The CT (CAT) scan, 1973 by Godfrey Hounsfield and Allan Cormack. The CT scan is great at providing detailed views of all types of tissues. Diagnoses many different types of cancer, being able to measure the size and location of tumors. The is a major breakthrough and is an abundant help. - The artificial heart, used to bridge time in a heart transplant or in some cases, permanently replaces the heart. Invented by Robert Jarvik in 1982.
These examples are only few of many. Many lives today have been saved thanks to the help of these machines. Technology has helped us so much, it's helped things become clearer, when we need to understand things. It's such an important aspect in today's society. Without technology things would be way different. We wouldn't be able to communicate as easily and things would be more complex. Also, medicine has evolved so much in the past years and we have incredible discoveries all the time. A major medical discovery was in the 1800s when anesthetics were discovered, which make surgeries painless and two Canadian doctors made great contributions to the developments in anesthesiology. In 1923, W.E. Brown of the University of Toronto established the value of ethylene as an anesthetic, and in 1942 Dr Harold Griffith advanced the science of anesthesia by his use of curare, a plant extract used by South Americans as an arrow poison. Technology in terms of medicine has also increased the life span of an average person.
I find that technology is one of the most important advancements for people. It's more than just aided, but it's changed lives, New things are discovered daily and I would hope and recommend the progression for the future.
Food is essential for growth, energy production, repair of cells and the maintenance of proper health. Without food, people would face serious consequences, they wouldn't be able to function. But where does food come from? Today there are about 6,900,201,659 people living in our society. Will we be able to continue to provide for ourselves as the years go by?
Agriculture plays a big part in this. There are two main types of agriculture, industrial agriculture and sustainable agriculture. Industrial agriculture is defined as "a modern form of capital intensive farming in which the machinery and purchased are substituted for the labor of human beings and animals." Industrial agriculture involves usage of heavy machinery and makes work easier, needing no labor. It has a negative impact on the environment. Besides pollution and soil destruction, it also consumes large amounts of water, energy and chemicals. Sustainable agriculture is a way of raising food that is healthy for consumers and animals, does not harm the environment, is humane for workers, respects animals, provides a fair wage to the farmer, and supports and enhances rural communities.
Without agriculture we're unable to produce food. Therefore agriculture has a big impact on us. It is estimated that in the year 2050 our population will increase to about 9 billion people! Because of the increase in population many farms will need to be built over with houses, replacing the sustainable agriculture. The industrial agriculture is more than sufficient and helps get the job done faster. But what about all the negative effects industrial agriculture has? Industrial agriculture seems to be the only choice. Even though industrial agriculture has negative impacts, but it also has a primary emphasis on speed, quantity and profit! Industrial agriculture supports facilities called factory farms but known to the government, they're called Concentrated Animal Feeding Operations(CAFOs). A large CAFO includes 1000 cattle (other than dairy, which is 700), 2500 hogs over 55 pounds, or 125,000 chickens (as long as a liquid manure system isn't used). The animals are confined closely and are unnaturally large. There must be other ways that we can continue to agriculture without affecting animals and ourselves. Because we're the ones consuming these mistreated animals.
Although industrial agriculture has a negative impact, it seems to be the only solution. Hopefully in the future we can develop better technologies to help provide for us, because who knows how long this will last. As Christopher Bond once said: "Advances in technology will continue to reach far into every sector of our economy. Future job and economic growth in industry, defense, transportation, agriculture, health care, and life sciences is directly related to scientific advancement."
