WRIT3152W Fall 2009: Science and Technology Issues

The article sweet obesity in seed magazine are considering about increasing the amount of obesity american lead people to think diet soda is good way to control the body condition and help them to lost weight. People usually think that drinking soda and eating something sweet which is contain sugar will gaining more weight but the research show that Low-calorie artificial sweeteners in diet soda gained significantly more weight than sugar-sweetened.

They also do the research with 2 rats, and feed them with diffirent diet, first one ate sugar sweetened and second ate artificially sweetened yogourt in addition to their usual diet of rat chow. Then after five week, the rat who ate artificial sweetners gained more weight than the rat who ate sugar-sweeted yogurt. Therefore, drinking diet soda may not losing weight and gaining weight is not cause by regular soda.

I am very much agree which this research because diet soda is not helping us losing weight, and normal soda will not be the reason for you gaining weight. That still depend on want you eat and what conditiion of your body. Some individuals are easy to gaining weight by eating a small amount of foods but others may not gaining any weight even though they eat a lot of food because it is depend on your body condition, if your body can burn fat faster than others than other you will not gaining a lot of fat but if you body can not burn fat easyly as other person, the fat remain in your body, if you keep eating food, the fat will increasing more but not burning, you will become obesity.

 I have a friend who is gain fat every easyly even she is trying to eat diet, and does not eating much during the day, but she still keep gaining weight. In the other hand, no matter what i am eatting i don't gain any weight as much as my friend does.It is not depend on diet food, diet soda to lose your weight but  I think it is still depend on other condition such as body condition, genes, and much more other things that make you gaining more weight. Eating condition may important but it is only affect a little bit.

The article I picked is called The Genomic Revolution.  This topic relates to what we have been talking about in class, selecting genotypes.  People have been depending on domesticated cows for many uses, such as milk.  Recently,   "Bovine Genome Sequencing and Analysis Consortium and the Bowince HapMap Consortium promises to revolutionize cattle breeding".   Cow genome involves analyzing and evaluating phenotypic records of cows to improve cattle breeding efficiency.  Over the past 50 years, industry has been able to "produce twice as much milk with half the number of cows through progeny testing".  Progeny testing is a process of evaluating the genetic value of lineages in cattle breeding.  Thus they can select a specific genotype to make cattle breeding more efficient. 

Another benefit from genotyping is to "select for livestock with the most efficient digestion, resulting in minimum feed".  Cow is a ruminant animal that can break down biomass and convert forage into usable energy.  "Lewin predicts that mimicking this cellulytic process and understanding the cow's microbial degradation process may prove vital in producing biofuels".  This study will help us to further comprehend digestion of low quality forage. 

The third benefit of studying the cow's genome would benefit the environment greatly.   If we could gain a better genetic basis behind the caloric efficiency of the rumen, we would control methane, a by-product from cow and the second most abundant greenhouse gas on Earth.  With further genotyping, we can control methane by selecting for livestock with the most efficient digestion.  If cows can efficiently digest their food, they would eat less and therefore, produce less methane.

Regardless of the benefits of bovine genetic study, only 0.04 percent of Department of Agriculture budget in 2007 was going toward agriculturally domestic animals research.  There is not enough funding to support it.

I think it would be okay to select specific genotypes in livestock to improve the agricultural systems.  I am not familiar with the agricultural system but I think how we use domesticated cows for meat, milk, etc. are no different from genotyping.  I recently learned that some cows are shot with a stun gun at the head to make it impossible to regain conscious.  Thus, I do not believe that genotyping is unmoral considering the ways cows are used for a variety of purposes and are slaughtered each year.  After reading this article on Seed Magazines, I think domestic animals research is essential since it plays a large part in our life.  Given that we have so many domestic animals, we can further use them to our advantage to go green by reducing methane production.  However, I am not sure about selecting cows to produce milk because there could be some factors in the milk that could chemically disrupt our body system.

            How many of you notice how technology keeps evolving for the better over a period of time? It seems that it was only yesterday when I first received my cassette player during Christmas time. Today, the cassette player is in my basement, and instead I am using my newest IPod touch technology. So what will happen in a hundred years from now? Will we have the cars that can fly? Will the cell phones be smaller than today's? How will technology impact our lives and make a difference in the future?

            This topic really interested me, and I decided to look for an article in the Seed Magazine with a similar interest. I found one about a new nanoscale storage device that can hold a maximum of a trillion bits of information. Alex Zettl, a physics professor, along with his team at the University of California, Berkley, researched and found a solution to such a problem. They created the technology that is able to hold a lot of memory and store important information without it ever getting deleted. "The system consists of a minuscule particle of iron encased in a carbon nanotube and represents information in binary notation" (Seed Magazine).

            Personally, I believe that this new technology invented by Alex Zettl is a very good idea. In my house, we used to watch a lot of VHS tapes since we did not have a DVD player at that time. Now, since we have the DVD player, we do not watch VHS tapes anymore since some are blank and got erased due to humidity, change in temperature, as well as the electromagnetic fields. So will this new technology work? Who knows? Zettl mentioned that this invention will last for more than a billion years. But will we know how long it can last for? No, since we will not live that long to confirm such a case!

            Have we as a society become so frightened by the though of the devastating H1N1 virus that we are willing to believe anything that is thrown at us. In times of crisis there are people who seek to take advantage of the crisis at hand. Producers also know that consumers are look for the quick technological fix. Many people do buy into the claim that "buy this product and you will be cured." There is a rule of thumb when confronting these product and that is if it sounds too good to be true, chances are that it is too good to be true.

 

There are web sites that claim to "kill" the H1N1 virus by simply spraying their "magic" potion on any surface. Company's are also using everything from gloves to masks to sanitizers to take advantage of consumers in fear. There is also a products such as ionic silver that can kill viruses, but it is not effective to the H1N1 virus.  

 

Now, anyone with a shred of common sense has to realize that a product will not be able to magically kill the H1N1 virus. If this was so there would be no need for the national emergency that we are currently experiencing and there would be no need to the H1N1 vaccine. There is a reason that the FDA must approve a product before they can claim to kill or cure the H1N1 virus. Currently there are only two products that the FDA has actually approved one of which is Tamiflu, according to an article by The New York Times. Take that into mind when you come across a product that makes the acquisitions even if the product claims to contain Tamiflu because most of the time there is only a minuet quantity of Tamiflu with in the product.

 

The false claims are keeping the FDA on their toes. The FDA must now patrol the web as if to be police and make sure that consumers are not scammed. According to The New York Times, the FDA has found 140 products that claim to win the war against the H1N1 and have sent out letters to 75 manufacturers telling them to remove their products from the web or sales floor. The FDA reports that about 80% of the companies that have received the letters have in fact taken there products down. If a company does not comply with the rules manufacturers can be reported to the 3^rd parties or host sites, their products will be taken down, and assets can be seized.

 

When contacted by The New York Times, Q-Based Solutions representative was asked if they sold anything to prevent swine flu and of course the answer was yes. The representative pushed their "healing gel" which was said to "kill the virus on anything that it is applied to." When asked if that included the H1N1 strain, the representative answered: "Yes, it's good for it." It is very possible that the representative did not hold any credentials to be making that claim that it would kill the H1N1 strain.

 

We must keep in mind not to trust any Joe Shmoe. There is no magical fix to the H1N1 virus. My simple advice is to take precautionary actions if you have not been lucky enough to receive the vaccine yet. Keep your hands out of your eyes and mouth, wash your hands, sneeze into your sleeve instead of into the open air or on your hand, and just use common sense when trying to stay away from the H1N1. In times of crisis we cant be looking to the easy technological fix. We are a society who thrives on science and technology, but at the same time we have to use common sense when coming across these products. These products however should not reflect or deter you from listening to your doctor, but do be skeptical of those who stand to make a profit such as the manufacturers.

Michele Serbus                                                                                                                     The article I read from SEED magazine was about animals becoming to evolved to fit specific niches and not being able to compete when new species are introduced into their environment. This phenomenon often happens in areas that are cut off, such as islands. When new competitors, often those brought over from the mainland from humans, the evolved animals face extinction because they are not able to adapt to the new environment. The question is do we intervene or let nature take it course?                                                                                     This would be seen by Darwin as natural selection. The fitter of the two or more species would survive. Often the species competing against these nearly extinct species is humans. We are competing constantly for land, water, and food. Humans have destroyed or greatly changed all the areas of the world, whether it be a land mass or the polar ice caps. As our population grows exponential, the populations of all other species that inhabit our environment can only be expected to decline.                                                                                   Many animals were hunted until extinction and many more are reaching that point now. These animals cannot be expected to be preserved in the wild due to illegal pouching and environmental factors, such as habitat change or climate change. The only other option is to house them ourselves in manmade habitats, thereby taking them out of their natural niches forever. By doing this we preserve apart of history for many generation, but really alter the animal's behavior in nature.

The article that I read was "A Natural Obsession" this article was very interesting in that it dealt with our food and organic choices.  The article downplays and shows many flaws in organic farming today, and shows a lot of pro conventional farming rationale.  It is definetely true that organic foods are sweeping across our country and that more and more people are switching to organic, but there are many reasons not to switch.

The article pointed out the obvious reasons of not being able to feed the world because of decreased yields in organic foods, but there were some more interesting things that I have never thought about before too.  Since organic foods have started to become more mainstream shipping them has started to become a priority due to the fact that organic foods can't all be produced locally.  The shipping alone is creating a much larger carbon footprint than conventional farming. 

The article also goes into more depth about how side effects have not been shown in pesticide use on conventional crops, but that the use of pesticedes has reduced the amount of plowing and tractor use in fields drastically also.  Less plowing means less erosion of the soil, and far less irrigation in areas where irrigation is needed. 

The part of this article that actually struck me the most though was the part about GMO's and integrity.  The article shows an example with wheat breeding.  Organic foods have all been cross bread in some time, but the difference between organic and gmo's is that in bioengineering of gmo crops everything is known exactly about the plant and seed.  Organic foods have the troubles of old breeding  have introduced entire foreign genomes, and radiation induced mutations that are actually quite scary when compared side by side to constructed crops.  Personnaly I believe GMO's are our future due to the fact that we have to feed an ever increasing population, and organic foods just aren't going to be able to keep up. 

The debate between the benefits of organic foods versus foods produced traditionally has a great affect on how we farm produce and how we will change this process in the not so distant future. A recent Seed Magazine article asserts that the allure to organic is, "They aren't in any way related to industrial-scale farms or big box grocery chains; chemical herbicides or pesticides; biotechnology or its subgenre, genetic engineering. And by those criteria they are deemed to be safer, more nutritious, and less damaging to the environment." The article goes on to say that these ideas are not exactly accurate, that diseases too are natural and that no so far in the 13 years of their distribution in the marketplace, no genetically engineered products have made anyone sick.  The article proceeds to discuss population increases, the demand for food as a result, and the space needed to produce the food; the history of Green technology; and the need for sustainable farming.

One of several of my questions, is how bad can genetically modified foods really be?

http://www.safe-food.org/-issue/dangers.html tells me that imprecise technology is one of four weaknesses of G.E.  Genes can be precisely cut from a gene but inserting the gene into the cell of another organism is actually random and problems could result. Side effects of G.E. are still unknown. Other things include, crop failure, toxins, environmental damages, more pesticides, some deaths.

Generally, these seem pretty bad. I must indicate that the statics included in the site were from the late 1990s, and GE has come far since then. Even if it has advanced the ramifications of what could happen are still frightening. This type of "gene power" is incredible to consider-- remarkable how far humans have come in a really short time - however, I cringe to think what this knowledge could do in despotic hands. Will someone come to power in my life who will attempt to physically craft a master race? Actually, be able to CHOOSE what people will look like, their intelligence, what they know? This is a bit dramatic admittedly, yet this seems be what most people in opposition of GE do fear. We are standing on the brink of this kind of power, in fact probably nearer to this kind of technology than the general public knows or is will to accept.

Can we use this technology to make sustainable farming work?  I think we are more than capable of doing this. Yet even if we can and do change policies on farming, laws cannot change attitudes. So it goes.

Can we reduce the rate at which world populations grow? Again I think the answer is yes. I am forced to pause when I see reality shows where families are 18 children large and the parents comment on how much food they go through in a few days or a week. I am not saying that the choices these people make are the cause for this problem. Not for a minute am I implying that. I do not think, however that propagating so freely is helping the situation either. I feel some kind of limitations must be made. I recognize that other factors get in the way in cases like these and often the motives to change will not be based on anything to do with the world populations, if they happen at all.

I really think the knowledge we have gained will give us what we need to mend that damages we've done in the past. But we must go about mending them in the proper way. It is not enough to merely invent something to fix an existing problem, only to cause more as a result. Each situation must be assessed as an individual problem or as a linked problem as the situation dictates. To really fix things and improve the condition and sustainability of the planet we shouldn't settle for quick fixes when it is clear that we have exceptional knowledge to tackle any obstacle. We must be smart enough to know when to think and when to invent. Only then can true progress be made.

It's always interesting when you walk into a grocery store and you overhear some of the conversations going on about why people are choosing some products over others.  I mean slogans and advertisements labeled on various products that read; "natural", "whole", and "real," how can you go wrong right?   Consumers have become more aware of what they are putting into their mouths in recent years.  However, have we become too concerned about the foods we have available for options?  I don't know if that is the main concern, but perhaps we sometimes have an instinctive thought that "natural", "whole", and "real" correlate to a more wholesome product that will be more beneficial for our bodies than some alternative options.  The article titled "A Natural Obsession" stated that there has been a skyrocketing popularity for organic foods.  Organic foods do cost more, but several consumers are opting to make the extra investment and buy the more naturally grown produces and products.  I do believe consumers should have the right to buy foods they feel comfortable consuming.  However, are we headed in the right direction for agricultural sustainability if we start offering more organic foods?

According to Ron Phillips, a professor at the University of Minnesota 14% of the world's population is estimated to be hungry.  He also stated that there are approximately 1.3 billion people in the world living on less than $1 per day.  Along with that all being stated, it is estimated that global food production will need to rise by roughly 50% in the next two decades to keep up with population growth (A Natural Obsession).  We have to keep searching for more ways to increase our efficiency and sustainability within agriculture.  I believe several of the reasons we have witnessed a big increase in demand for organic food is because of the general public's level of uncertainly in regards to health with biotechnology in agriculture.  People become concerned when they hear about genes from one organism being inserted into the DNA of another organism.  People start thinking about potential health issues when they hear or read about such practices.  "It is estimated that 70% of the processed food sold in the United States contains GM (Genetically Modified) products either directly or indirectly, as when GM crops are fed to animals." (The World Food Problem)  Agriculture is surrounded with GM technology, and should some of the progressive technology we have become accustomed to be shy away from, and perhaps be taken out of the hands of the producers?  Will we be able to keep up with the food demand of the world population if we choose to discontinue the popular conventional production methods and opt for more production of organic produces?

Response to the Seed interview: Jason Matheny on the worlds addiction to meat and how to grow ground beef in a test tube

    New Harvest is a non-profit organization that investigates the development of new meat alternatives, cultured in vitro. The very idea of this seemingly bizarre proposal arose due to the fact that the world's demand for meat is increasing rapidly. Unfortunately, this increase in demand has led to an accumulation of health related issues such as cardiovascular disease and high cholesterol levels. Meat production requires a great deal of resources as is the direct result of animal cruelty, "New Harvest's goal is to push forward technology that could be satisfy the growing global demand for meat I a way that's healthier, more energy-efficient and sustainable"

I happened to come across a rather intriguing interview between Seed Magazine's interviewer, Lee Billing and New Harvest's co-founder and director, Jason Matheny. Matheny provided Seed with numerous reasons as to why food scientists are looking into producing beef in vitro. Circumstances have proven that the global demand for meat has led to a "vast environmental footprint". For this reason, including the ones previously mentioned, Matheny has taken it upon himself to further explore the possibility of commercially produced in vitro beef.

I'm sure that anyone who decides to read this interview to completion will become a skeptic to even the slightest whiff of this scheme. Meat....made is a lab? Under what conditions exactly is this so-called meat being prepared? The very thought of it makes me uneasy. In vitro meat is "unnatural" they say; well, so is the commercial production of chicken, milk, yoghurt, cheese, bread and genetically modified foods. Unmistakably, on such terms, cultured meat might sound like a pretty good idea. Another reason why this endeavor may seem appealing is acknowledging the fact that bioreactors not only have the ability to make meat, but they also have the ability to customize its content. This draws attention to the likeliness of reducing the worry about food-borne illnesses, such as high-blood pressure. This would allow customers the opportunity to consume fat-free beef or vitamin fortified meat.

I'll admit, Matheny provides a pretty solid argument as to why this technique may become acceptable sometime in the near future. But what if a potentially harmful substance finds its way into the cultured meat? Are we in a position to face the possibility of consumers ingesting poisoned meat? What about the long term effects of its commercial use? Matheny suggests that further investigations could lead to breakthroughs in the exploration of artificially manufactured, functional organs. Could this discovery truly elongate lives, or shatter them in the long run?

Oh, and did I happen to mention that Matheny is VEGETARIAN...ironic, to say the least!
