Good start, Ronnie, but give some detail so that we can see what evidence their is to support these claims (and see what the claims are more specifically - they're a little vague as worded here).
Delete1. Although fruits and vegetables tend to grow only in certain seasons, we have them all year 'round. How? Tomatoes, for example, are grown halfway around the world, picked when it was green, and ripened with ethylene gas. It is then sent miles and miles and miles to our supermarket. It's not REALLY a true tomato, just our ideas of what a tomato is.
ReplyDelete2. When a chicken starts off as a little chick and in only a matter of weeks have a large five-pound + chicken, their bones and internal organs aren't able to keep up with the rapid unnatural growth. They can't even move with all the weight.
3. Antibiotics are put into the feed that is fed to the animals which then goes into our foods and our bodies. But the bacteria begins to build a resistance to the antibiotics and nothing is done about it because it would cost the multi-coporational businesses more money.

Great job, Gabby - very interesting findings. Just so everyone knows, ethylene gas is something that vegetables themselves give off as they're ripening (not that the industry isn't adding the gas to ripen the veggies, just that it's not a totally foreign material being introduced into the process). This topic is really eye opening!

It would be interesting to see if bullying *period* is increasing/did increase, or if it just shifted into a new form? That is, did the overall total amount of bullying stay the same, but now some/much of it is done via social networking, or did the total overall amount go up, so the social network bullying is in addition to classic bullying? Did that make sense?

In Society-Increases the food security for many growing populations.
Controversies:
In Safety-There are potiential human health impacts, such as allergens, unknown effects, and even a transfer of antiobiotic resistance markers. In addition, there are potiential environmental impacts, such as unknown effects on other organisms (e.g., soil microbes).
In Access and Intellectual Property-May become dominant for world food production by a few companies or even Biopiracy, which foreign exploitation of natural resources.
In Ethics-Tampering with nature by mixing genes together among other species, stress levels for animals increases, objections of consuming animal genes in plants, and or consuming plant genes in animals
In Labeling-May not be mandatory in some countries, for example the United States. And, some mixed GMO products with non-GMO products are not labeled.

The Progressive Increase of Food Waste in America and
ReplyDeleteIts Environmental Impact
Kevin D. Hall
Food waste contributes to excess consumption of freshwater and fossil fuels which, along with methane and CO2 emissions
from decomposing food, impacts global climate change. Here, we calculate the energy content of nationwide food waste
from the difference between the US food supply and the food consumed by the population. The latter was estimated using
a validated mathematical model of metabolism relating body weight to the amount of food eaten. We found that US per
capita food waste has progressively increased by ,50% since 1974 reaching more than 1400 kcal per person per day or 150
trillion kcal per year. Food waste now accounts for more than one quarter of the total freshwater consumption and ,300
million barrels of oil per year.
The Progressive Increase of Food Waste in America and
Its Environmental Impact
Recent spikes in food prices have led to increasing concern
about global food shortages and the apparent need to increase
agricultural production [1,2]. Surprisingly little discussion has
been devoted to the issue of food waste. Quantifying food waste at
a national level is difficult because traditional methods rely on
structured interviews, measurement of plate waste, direct examination
of garbage, and application of inferential methods using
waste factors measured in sample populations and applied across
the food system [3–6]. In contrast, national agricultural production,
utilization, and net external trade are tracked and codified
in detailed food balance sheets published by the Food and
Agriculture Organization of the United Nations (FAO) [7]. The
food balance sheets provide a comprehensive assessment of the
national food supply, including alcohol and beverages, adjusted for
any change of food stocks over the reference period [8]. Since
1974, there has been a progressive increase in the per capita US
food supply. Over the same period, there has also been an increase
of body weight as manifested by the US obesity epidemic. We
sought to estimate the energy content of food waste by comparing
the US food supply data with the calculated food consumed by the
US population.
The calculated progressive increase of food waste suggests that
the US obesity epidemic has been the result of a ‘‘push effect’’ of
increased food availability and marketing with Americans being
unable to match their food intake with the increased supply of
cheap, readily available food. Thus, addressing the oversupply of
food energy in the US may help curb the obesity epidemic as well as decrease food waste, which has profound environmental
consequences
Assuming that agriculture utilizes about 70% of the freshwater
supply [13], our calculations imply that more than one quarter of
total freshwater use is accounted for by wasted food. Furthermore,
given that the average farm requires 3 kcal of fossil fuel energy to
produce 1 kcal of food (before accounting for energy requirements
of food processing and transportation) [14], wasted food accounts
for ,300 million barrels of oil per year representing ,4% of the
total US oil consumption in 2003 [15]. In addition to this wasteful
consumption of fossil fuels and their direct impact on climate
change, food waste rotting in landfills produces substantial
quantities of methane [16] – a gas with 25 fold more potent
global warming potential than CO2 [17] which would have been
the primary end product had the food been eaten and metabolized
by humans.

ReplyDeleteAuthor Jonathan Bloom Digs through the Problem of Billions of Tons of Food Waste
Every day, America wastes enough food to fill California's 90,000-seat Rose Bowl Stadium, according to Jonathan Bloom, author of American Wasteland How Amelia Throws Away Nearly Half of Its Food (and What Wet an Do About It) (Da Capo). This past May, the food and Agriculture Organization of the United Nations (FAO) reported that roughly one-third of the food produced in the world for human consumption every year, some 1.3 billion tons, gets lost or wasted. People in America and other wealth}- nations topped the food-wasting list because they "can afford to waste food," the FAO report noted.
U.S. homes and businesses threw out more than 34 million tons of food in 2009, the U.S. Environmental Protection Agency (EPA) reports, which amounts to more than 14% of the nation's total municipal solid waste stream. Paper is the only material category where Americans generate more waste, but while 60% of paper is recycled every year, only 3% of food scraps are turned to compost. The remaining 97% is sent to landfills where it rots and produces harmful, potent, heat-trapping methane gas. According to the EPA, composting would eliminate landfill methane emissions as well as "regenerate poor soils, suppress plant diseases and pests, reduce or eliminate the need for chemical fertilizers, and promote higher yields of agricultural crops," but only a handful of cities like Seattle, Washington, San Francisco, California, and Boulder, Colorado, offer residential curbside composting pick-ups.

Organic movement - Organic farming is the way to go
ReplyDelete1) Organic Manifesto: Five Solutions That Might Save Us (http://0-web.ebscohost.com.alice.dvc.edu/ehost/pdfviewer/pdfviewer?sid=397e6b1b-41ef-47b4-a644-9d5b14c90cf9%40sessionmgr14&vid=4&hid=21) - Government needs to ban agricultural chemicals and GMO's. "The government must stop subsidizing chemical farming. We need to completely overhaul the farm bill to encourage as many farmers as possible
to transition to organic as quickly as possible... Reorient the incentives so that the prices of organic foods and agriculture fibers reflect their real costs and are affordable." Tax structure should be aimed at taxing polluters at the highest rates thus giving tax breaks to the companies and people who are helping the environment and looking out for the health of the nation. We need to enforce and keep USDA organic standards pure not allowing the rules to weaken so chemical companies can sell products to farmers. Farmers must supply organic demand.. The wealth comes from the knowledge and feeling that one is doing a good deed, that love it comes from love for the environment, for society, for the children. Create innovative solutions, "The business community needs to support and enrich people and the planet—not the other way around. There is a movement growing around the idea that businesses can be leaders in making positive change for the world. It started with the concept of social responsibility and now has names like conscious capitalism and natural capitalism. Many successful companies now reflect this fresh modern ethic—companies such as Patagonia, Stonyfield Farm, Nature’s Path, Organic Valley and, yes, Whole Foods." Economists need to measure strength and not growth. "True crime of Wall Street and our economic model is that they instilled the expectation and valuation of constant growth rather than the recognition of the cycles inherent in nature and the valuation of long-term strength."
2) Organic Foods Contain Higher Levels of Certain Nutrients, Lower Levels of Pesticides,
and May Provide Health Benefits for the Consumer (http://0-web.ebscohost.com.alice.dvc.edu/ehost/pdfviewer/pdfviewer?sid=d846e8c0-ed4e-489b-86ee-1cb931f5ccfb%40sessionmgr11&vid=4&hid=21) -
"Lairon's review'" reported that, regarding minerals, organic foods have 21-percent more iron and 29-percent more magnesium than non-organic foods. When vitamins were studied, ascorbic acid was the most common vitamin found in higher quantities in many organic fruits and vegetables tested. Worthington" reached much the same conclusions, stating that four nutrients were found in significantly higher levels in organic produce. ascorbic acid averaged 27-percent higher, iron 21-percent higher, magnesium 29-percent higher, and pbosphorus 13.6-percent bigher. Both Worthington and Lairon reported the studies they reviewed showed conventional foods were typically higher in nitrates - 15 percent higher in conventional foods according to Worthington. Organic foods have more vitamin C, iron, phosphorus, and magnesium than conventional foods. While this is an important finding, it is cast in a brighter spotlight when it is recognized that during the last 50 years vitamin C, phosphorus, iron, calcium, and riboflavin content has been declining in conventional foodstuffs grown in this country.
Is this still Dewight? see above :-)
DeleteQuantities of some nutrients seem to be increasing in organic foods, organic foods appear to provide better nutrition.In a study of the potential for vegetables to suppress the mutagenicity of various environmental toxins, including benzo(a)pyrene (BaP, tbe main carcinogen in cigarette smoke and auto exhaust), organic vegetables were more active than their conventional counterparts. Against the chemical 4-nitroquinoline oxide, organic vegetables suppressed 37 93 percent of the mutagenic activity, while the commercial varieties suppressed mutagenicity by 11-65 percent. Wben measured against BaP, organic vegetables suppressed 30-57 percent of the mutagenic action, wbile commercial vegetables only suppressed 5-30 percent of the mutagenic activity. Organic strawberries also block proliferation of HT29 colon cancer cells and MCF-7 breast cancer cells. For both cancer cell lines the extracts of organic berries were more potent in reducing cellular proliferation than conventional strawberries. Essential fatty acids: Statistically significant increases (from 0.25 weight % to 0.29 weight %) were found for the women who ate a moderately organic diet compared to the conventional diet, and an even greater
ReplyDeleteincrease (0.34 weight %) for those who ate the strict organic diet. Consumption of organic dairy products did result in a statistically significant advantage for lower eczema, those children consuming organic milk and milk products having a 36-percent reduction in risk of having this allergic skin disorder.
3) "American agriculture relies on close to one billion pounds of pesticides and herbicides each year. As a result, many vegetables are coated with pesticide residues. Although the doses are small, over time they can build up in our bodies. Twenty million American children between one and five years old ingest at least eight pesticides every day, according to the Environmental Working Group. Some 610,000 kids consume insecticides, mostly from apples and peaches, that the government deems harmful to their fragile nervous and hormonal systems."
"More than 90 percent of pesticides used in California are prone to drift, and roughly a third of those are highly toxic to humans, according to Californians for Pesticide Reform (CPR), a coalition of environmental groups. Numerous studies suggest that these airborne toxins may carry serious perils to human health, such as elevated levels of non-Hodgkin's lymphoma among farm owners and operators, and increased rates of cancer, birth defects and spontaneous abortions among farm workers."

Acordng to Better Health Chanel in their article “Genetically Modifued Food” mention that GMOs is been in the industry for any years, and is use to make animals/plants tolerant to weather, bacterial, virus or disease that may affect it. GMOs may have vitamins, minerals and nutrient added to “increase the amount of particular nutrients in food crops.” Many web sited as well as Better Health web side have stated that GMO food have better taste, quality, nutrients, is cheaper and better for the environment since they do not have to apply the same amount of chemicals as non GOMs food. The chemicals applied to the food are use to kill the animals/bacteria and prevent the animals from eating the food. The negative aspects about GMOs are that people can develop new allergies since food genes can be injected to another. A good example of this is white rice. If people are allergic to Vitamin A they should not eat GMO rice since many have been injected Vitamin A to prevent malnutrition from people in Africa. GMOs on animals can also affect citizens health since there are hormones and antibiotic added. GMOs can also affect organic food since bees distribute the pollen and the contaminated pollen from GMOs grown farms can contaminate the organic ones.
ReplyDeleteAlso on the article “Monsanto: Genetically Modified Food and the Need for Reforming Food Safety Laws” by Emma posted on Jan 25 2010 mentions that genetically modified food by Monsanto may cause liver and kidney problem and a deasease called Hepatorenal which according to Rajendra Bhimma, MB, ChB, MD, DCH (SA), FCP (Paeds)(SA), MMed (Natal) Associate Professor of Pediatrics, Principal Specialist, Department of Pediatrics and Child Health, Nelson R Mandela School of Medicine, University of KwaZulu-Natal, South Africa, and some other authors that can be found in “Medscape Reference” web site in the article named “Pediatric Hepatorenal Syndrome” stated:
That there are “two types of hepatorenal syndrome are described. Type 1 hepatorenal syndrome is mainly associated with acute liver failure or alcoholic cirrhosis but can also develop as a result of other forms of liver failure. It is characterized by rapid deterioration of renal function that usually occurs within 2 weeks, with an increase in serum creatinine and BUN levels and a substantial decrease in the glomerular filtration rate (GFR). Hyponatremia and other electrolyte abnormalities are common findings. Type 2 hepatorenal syndrome has a more insidious onset and is characterized by a steady and progressive decline in the renal function as well as recurrent, diuretic-resistant ascites. It generally occurs more often in patients with hepatic dysfunction less severe than that observed in type 1. Both type 1 hepatorenal syndrome and type 2 hepatorenal syndrome are associated with a poor prognosis”
It also mentions that GMOs could be toxic.
there are way more thing to add, but this is just to much for you to read right now so i will just give this info.

1. The earliest usage of rhetoric can be found in Akkadian texts dating from the 2200's B.C but the first study on the power of language is attributed to Empedocles in the 440's B.C. and the first written manual on the subject is thought to be written by Corax of Syracuse, a founder of the Sophists, in the 5th century B.C.
ReplyDelete2. In the time of Empedocles, Isocrates, Plato, and Aristotle (all of whom wrote or spoke extensively on rhetoric), the written word was an emerging technology and public speaking was the dominant form of media; because of this, coupled with the manipulative advantage a trained speaker could have over an audience, rhetoric has been a matter of concern an controversy ever since its inception as a formalized art.
3. Aristotle defined rhetoric as "the faculty of observing in any given case the available means of persuasion" and defined three elements of the practical art: logos (logic), pathos (emotional appeal), and ethos (the ethical standing of the orator and/or his argument).
It seems like my particular subject, what rhetoric is and why it is important to our society now, is going to be filled with a lot of interpretive claims. There is plenty of research materials to support them but the basic argument is a value judgment that is difficult to argue with empirical absolutism.
Craig W.
I'm a little concerned that if you're trying to do such a broad historical scope, it won't leave you any time to do your *own* deep analysis of the contemporary use of rhetoric. I want to be sure that you're taking a small enough bit to really chew, if you will.

Delete1.) What I learned from the research activity is that according to Massachusetts’ recreation and park association, there is a great deal of stress when it comes to Americans. In a study it states that 89% of Americans said that they were feeling stressful in their life. It also shows that if anyone does or goes to the recreation center then their stress will decrease. The recreation activities will make people be active and think about what makes them happy. It is going to make the "bad' stress go away. So, the recreation centers will be really helpful.
ReplyDelete2.) There is a study that shows that if people do exercise then they will be able to concentrate better when they go to school or in general. The study also emphasizes that with exercise the body will go into a state that will make them be able to go into a deep sleep. Also, it is going to make them more rested for the entire of the day because the body does not have a lot of energy. The recreation center will make this possible.
3.) I also learned that with recreation centers, the community of people that will be involved, as a consequence to all the exercise their self-esteem is going to improve. The park can create pride in the community of people who did not previously care about their neighborhood, people will feel proud that they can go to a safe and clean environment, therefore It would create new behaviors that they will reflect on and make them improve on the things that they would want to. They will be able to relay on themselves. So, the recreation centers will play a big role on this.

When the National Radiological Defense Laboratory was operative, it was the only laboratory to be working on nuclear research issues. The mission of the laboratory was to study the thermal and nuclear radiation effects on atomic weapons and how to protect against them. The laboratory operated at a time when little was known about the deadly effects of nuclear material and radiation poisoning. The NRDL overlooked safety precautions that we now know today would be deemed fundamental. According to one Hunters Point resident, men who worked at the NRDL were required to shower every day after work in order to remove any radiation. Another resident disclosed that a friend, who once worked at the NRDL, was hired to carry barrels of radioactive material from one location to another. This was a job he held for years before developing a giant tumor in his stomach.
ReplyDelete(Finch, Trouble in Paradise: Postwar History of San Francisco’s Hunters Point Neighborhood)
The NRDL often experimented with the disposal of nuclear material with little concern that the facility was located in San Francisco, a major metropolitan area. Based on historical documents, some of the things the NRDL scientists did:
- Conducted human experiments that included having people drink radioactive elements.
- Sold radioactive scrap metals for ships
- Spread radioactive material on and off the base to practice decontamination.
- Dumped huge amounts of radioactive sand and acid into San Francisco Bay.
- Hung a source of cobalt-6o, a nuclear isotope that emitted high amounts of radiation similar to x-rays, in S.F. Bay just to see what would happen.
(Davis, IRE Journal)
The Navy believes that the residual radiological contamination at Hunters Point is primarily the result of NRDL atomic weapons testing material and Atomic Energy Commission licensed material. Radium and strontium were used in radioluminescent devices. The process of trying to decontaminate ships that had been a part of atomic testing in the Pacific created radioactive waste. Material from atomic weapons testing is exempt from NRC licensing under Section 91(b) of the Atomic Energy Act. The Navy believes that AEC-licensed material and weapons testing material are commingled because both materials were used by the NRDL. These materials have the potential to exist in the storm drains, sanitary sewer lines, septic systems and in one of the landfills at Hunters Point. Under superfund law, the military service that operated the site is responsible for implementing the cleanup. Rather than exercise its regulatory authority for the licensable radioactive material assumed to be present, the Commission has decided NRC will rely on the ongoing Navy remediation. The NRC would like to reserve the option of commenting to the EPA if necessary.

San Francisco will ask the state to conduct its own investigation of the cleanup of radioactive waste on Treasure Island, after receiving complaints that contractors hired by the U.S. Navy might have mishandled contaminated material
The Navy is preparing to transfer the former Treasure Island Naval Station to San Francisco next spring, allowing for a planned 8,000-unit housing development. Under a 2010 agreement signed by former Mayor Gavin Newsom and U.S. Rep. Nancy Pelosi, a San Francisco Democrat, the city is to pay the Navy $105 million plus a share of development profits – as long as the Navy meets a series of transfer deadlines, which hinge in part on a timely cleanup of hazardous waste.
The Navy and the state Department of Toxic Substances Control say that Treasure Island poses no health risk to residents and that the government is conducting a complete cleanup of the area. After The Bay Citizen reported that radioactive contamination on the island was more widespread than previously disclosed, two dozen of the island’s 2,500 residents met with Navy officials to ask why they had not been informed about the potential dangers. Long-term exposure to radium, the most common radioactive material found on the island, potentially can increase the risk of diseases such as leukemia and bone cancer. Those diseases, when they do occur, often appear years after exposure. But even then, it can be difficult to prove a connection between exposure and illness. The Navy decommissioned the Treasure Island Naval Station and opened it to the public in 1996

Do Rec centers reduce rate of crimes?
ReplyDeleteIn the article i read it explained how Cumberland County in Fayetteville it explained that one out of three roberies came from someone under 16. one rec center wants to change that by changing lives. being active is a good way to stay out of trouble as well. http://www.wral.com/news/local/story/154450/
I learned that being active can change your life and can save your life in majority of ways.For example, if you are big and or fat, out of shape, you can die of heart attack, and or get diabetes. Another way it can change your life is staying out of the streets, which can lead to drug selling and getting in to gangs. which is the wrong direction in life. from personal experience in which i seen in life.

I also learned that being active can lead to kids having good benefits by having strong bones, weigh control, better sleep, and a better outlook on life.http://kidshealth.org/parent/nutrition_center/staying_fit/active_kids.html

Hey Trevor, could you put this in your own words? You're processing the information at a significantly higher level if you reword it rather than cutting and pasting.
Delete1. The City of Oakland, Office of Parks and Recreation operates multiple community-based centers. 20 to be exact: Allendale, Arroyo Viejo, Brookdale, Bushrod, Carmen Flores, deFremery, Dimond, East Oakland Center, FM Smith, Franklin, Golden Gate, Ira Jenkins, Lincoln Square, Manzanita, Montclair, Mosswood, Rainbow, Redwood Heights, San Antonio, Sheffield Village, Tassafaronga, and Willie Keyes.
ReplyDeleteThere are free and low cost programs for people of all ages. Such as sports, arts and culture, computers, general learnig, after school activites and more.
Even though all these places are referred to as recreation centers, I have been to 3 of the locations for basketball tournaments and I have only noticed a basketball court. I did not see any other rooms for different activies.
Source: http://www2.oaklandnet.com/Government/o/opr/s/facility/index.htm
One issue: If there are so many recreation available for children in Oakland, why is the crime rate still so high? Are kids not taking advantage of these facilities? and Why?
2. According to the US Census Bureau in 2010, Oakland has been reported having 34.5% white people, 28% black, .8% American Indian and Alaska Natives, 16.8& Asians, .6% Hawaiian and other Pacific Islander, 5.6% reporting two or more races, 25.4% Hispanic or Latino origin, and 25.9% White persons not Hispanic.
I wanted to know demographics of the people living in the city of Oakland because "crime remains one of Oakland's most serious challenges, and Oakland continues to have a reputation among its own citizens, its understaffed police force, and residents of other Bay Area cities as a dangerous place, with one of the top five highest rates of violent crime in the U.S" according to Wikipedia.
Source: http://quickfacts.census.gov/qfd/states/06000.html
3. I begin to think that children starting at a young age are not being notified of such recreation centers. I think schools should have flyers and make sure that all their students are aware that they can have access to these places. However I couldn't find any facts or sources that concers this. Help? group members... Thanks!

Social Networking (media) & Teens
ReplyDelete1. Teens who spend time on Facebook, MySpace, Twitter, and other social networking sites may be more likely to smoke, drink alcohol, and use drugs.
2. according to Columbia University's National Center on Addiction and Substance Abuse (CASA). CASA recently polled more than 2,000 teens online or by phone, as well as 528 parents of teens.
The results show that compared to teens who don't visit social networking sites daily, those who do are:
Five times more likely to use tobacco
Three times more likely to drink alcohol
Twice as likely to use marijuana
Most teens -- 70% -- said they spend anywhere from one minute to hours a day on social networking sites.
3. teens who reported that someone had posted nasty or embarrassing things about them online are at greater risk for substance abuse. One in five teens aged 12 to 17 have been cyberbullied, the survey's showed.
Ah, good. This stuff seems a little more quantitative, so that's helpful.
Delete1. Violence: The violent content we see today has increased in frequency, young kids and teens are exposed to heroes who are ever more violent with cooler than ever tricks and moves (most of which are done by stuntmen or are computerized). With regular exposure to violence, teens (especially boys) are more likely to practice the moves and incorporate them into daily life when interacting with peers.
ReplyDeleteArticle Source: http://EzineArticles.com/6816865
2. Substance abuse: There aren't many movies that do not include alcohol and drugs in at least one of the scenes, particularly when teens are partying. Alcohol and drugs are consistently paired with the idea that these substances help teens have more fun. More importantly, media portrays these scenes as reflection of reality leaving teens believing that everyone does it. As soon as teens feel singled out, they are more likely to conform to what they think is normal.
Article Source: http://EzineArticles.com/6816865
3. Media: The effects of video games, the internet, and electronic devices are harder to pinpoint simply because these media are newer than television, but it goes without saying that too much can be harmful to teens. The internet is particularly troublesome because in many ways it is a more extreme version of television. Unsupervised, a teen is capable of finding practically any type of content online, and the web is filled with violent, sexual, and hate-filled content, always just a few clicks away. Meanwhile, the rise of social media has raised a new set of issues, including the potential for oversharing, harassment, and cyberbullying.

Delete1. "When one modifies the genes of a plant to make a GMO, there is the alarming possibility that this new gene may cause an allergic reaction in certain people and scientists claim that GMOs have negligible health impacts in the short term, studies such as this suggest that they might dramatically alter human biology in the long term. Therefore, it is unwise to put these foods on the shelf before we are definitely sure that they will cause no harm to humans in the years to come."
ReplyDelete2. "the production of GMOs is a lengthy and very costly process. Greedy companies seeking outside investment patent specific genes and species, thus leading to costly legal cases involving patent infringements. These cases often delay companies from continuing production of crops, thus decreasing their efficiency and also minimizing profit. Yet the worst economic drawback of GMOs is their effect on the heart of the agriculture industry"
3. "Scientists believe that these plants could spread exponentially and become tolerant of herbicides, meaning that they would be almost impossible to destroy. Thus, instead of making farming more efficient, GMOs have a strong likelihood of backfiring to make weeding crops much more difficult. Such a result would have disastrous economic ramifications. GMOs, therefore, are not worth the risk."

Do they have the information about the studies that showed long term health effects from GMOs? It's important to include that in your thinking about the issue.

Interesting stuff, and good to kickstart more research!
Today’s American teenagers are digital natives — connected to the Internet since youth. About 75% of 13 to 17-year-olds have personal social networking accounts. Since 2008, there has been a huge spike in teenage connectivity; only 59% of teens were on social media four years ago.
ReplyDeleteDespite seeing “racist, sexist and homophobic content” online, teenagers view social media networks positively. A national survey of 1,030 13-to-17-year-old individuals, conducted by Common Sense Media, reveals teenage perceptions of their digital lives.
More than 90% of teenagers are connected to the Internet. About 68% of teens regularly text, 51% visit Facebook and about 11% send or receive tweets every day. Many teens, 41%, admit they’re “addicted” to their devices.

DeleteParticularly in numbers 2 and 3, give some more detail so we can see what evidence there is for those claims.

DeleteFarming Practices - Harmful Farm Chemicals By Philip Foster
ReplyDeleteThere are several of chemicals found in use for modern day
use in farming that have a detrimental effect on the human body. The Environmental Protection Agency have named an estimate of 20,000 types of chemicals being used in farm related incidents. Which has caused many Americans to be more aware of where they get they're food from.
Pesticides
This alone, makes up the majority of chemicals being used in farming. However it is considered legal to use, however it can cause harmful development issues in developing children. The study also suggested consuming chemical pesticides might contribute to testicular, brain, prostate, breast, and stomach cancer. Many categories of pesticides exist including insecticides, fungicides, herbicides, and rodenticides. Insecticides are used to kill the bugs that commonly feed on crops. Certain insecticides contain harmful phosphorous materials. Farmers use fungicides to kill fungus that grows on and destroys crops. Fungicides often come into direct contact with the area of the crop that is consumed. Fungicides can also contain harmful metals such as mercury and copper. Herbicides can have detrimental effects on the crop itself as herbicides are used to kill any weeds surrounding the crops. Rodenticides are used by farmers to kill the rodent population, including mice and rats, which feed on crops. Rodenticides might contain harmful metals that act as a poison when consumed by humans.
Heavy Metals
Heavy metal chemical substances often enter into produce and food items through the machinery used by farmers in the production process. Common heavy metals found in the food supply include mercury, cadmium and lead. Mercury can destroy human brain cells as well as contribute to diseases such as Alzheimer's. Cadmium has been associated with causing various types of cancers, while lead can cause serious brain dysfunctions in young children. Lead can be harmful to humans in even a small amount.

Delete1. Without the contact of other people, face to face, people become antisocial and dont develop social skills.
ReplyDeletehttp://www.the-modern-christian.com/addressing-the-myth-homeschooling-leads-to-antisocialism.html
2. Now even the unemployed and the unemployable network. Teenagers, Moms, Grandmothers, and Stay-at-Home Dads all in some way or another have become networkers. Face-to-face conversation has become practically nonexistent and even romantic attractions are prefaced with the words, “Do you have a Facebook?” Here’s the issue though: With all the networking going on people have become more and more antisocial.
http://www.dragonblogger.com/the-anti-socialism-of-social-networking/
3. There are two main reasons that the Internet does not bring people closer together. First, it eliminates interactions. Second, it dehumanizes communication. By searching on the Internet for places to eat or shop, they eliminate conversations that used to be held between friends and family. Then, when there are conversations on the Internet, because of the lack of face time, there is so little substance that no lasting connection is made. Also, these conversations tend to not be genuine, because people will say things online without thinking, which, as social creatures, is not the way we were set up to interact. In conclusion, I feel the Internet makes people more isolated and jaded towards their fellow human beings.

I'm pretty sure that in #1 above, the source is saying that some people *claim* that homeschooling leads to social alienation, but that it's not true. So you'll want to take another look at that source and make sure you've read it right.

1. Some say GMOs will reduce world hunger in developing nations by creating plants that are more resistant to pests, disease, and extreme weather conditions. But Scientists from developing countries fear that gene technology could undermine poor nations' abilities to feed themselves by destroying established diversity, local knowledge, and sustainable agricultural systems.
ReplyDelete2. GMOs can improve health in developing countries by delivering drugs and vaccines inserted into banana and potato crops in areas lacking in refrigeration and without access to immunizations. But again relying on administration of drugs and vaccines through bananas and potatoes can be arbitrary. How many bananas or potatoes would be appropriate per pound of body weight, per day to supply adequate protection? The threat of developing resistant strains to any drug is an ongoing event in nature.
3. There are currently two bills before Congress dealing with GMOs. The GE Right to Know Act, cosponsored by Rep. Dennis Kucinich (D-OH) and Senator Barbara Boxer (D-CA). This bill would require proper labeling of all food products containing any ingredients from GMOs.
A second bill sponsored by Dennis Kucinich, The GE Food Safety Act this would require agri-business to first prove the safety of new products before introducing them into the marketplace.
