A Closer Look delves into the farming practices in regions across America while Science in the News reports on Pfiesteria, a bizarre organism that kills fish. A Closer Look examines the process of hydroponics which was developed in the 1930s. Hydroponics is the growing of plants in the absence of soil. The natural way of farming includes tilling, sowing, watering, and crop rotation which can be a gruesome practice that is not always successful. By use of hydroponics, farmers instead use water and nutrient solutions to grow their crops. The genre of the text is science. The main focus of the text is to bring awareness to the benefits and drawbacks of hydroponics on the Earth and society by utilizing Chris Killenberg. Killenberg is the head of …show more content…
The author tells the narrative of this text and engages with the reader by asking questions about their opinion on hydroponics. The narrative is manipulated by the author to propose hydroponics as a viable solution to farming needs. The drawbacks of hydroponics are only illustrated in one paragraph of the text while the benefits are listed throughout. The knowledge put forth by the text can only be concluded to be from a scientist or a well-read researcher who decided to write an article at an elementary based level. The academic language presented by the article is quickly explained and defined within the passage. There may be challenges for a novice reader because there are a few words that might confuse the reader if they do not know the meaning. To make the text more accessible and understandable the author puts definitions in parentheses. The only visual image in the text is of a picture of Chris Killenberg overlooking his lettuces. The text and image work together because the image is adequately placed right next to the introduction of Killenberg. The image, along with the text, shows that Killenberg has a great deal of power as head of his company. The article puts forth into question whether there is manipulation by the hydroponic industry to create a sense of security for farmers to use its process. Not enough sufficient research or knowledge is known about the drawbacks of hydroponics. There is still no …show more content…
Pfiesteria is baffling researchers because no one has been able to find out how Pfiesteria kills fishes or how it sickens people. Nor scientists know why the bacteria thrives in polluted water. Scientists have yet to be able to pinpoint or predict the outbursts of Pfiesteria. The genre of the selected text is science. The main argument of the article is that it is alarming to know so little about a bacteria killing organism. The main focus of the article is to inform the reader of the harm Pfiesteria has on the environment and how the bacteria’s appearance is possible a direct outcome from the damaging pollution of the “state’s fertile but fragile estuaries”. Direct exposure of Pfiesteria has proven to be sickening to people after watermen on the Pocomoke River in Maryland felt their minds addled after reeling in nets full of sore-pocked fish. The point of view is told from a journalist or researcher who wishes to bring more attention of Pfiesteria. The narrative is being told by someone who appears to be equally worried about the effects of Pfiesteria and how it could negatively damage the ecosystem. The narrative is being told with a sense of urgency towards a call for more information to be discovered about the bacteria. The knowledge is of educated scientists conducting research on the bacteria and concluding the bacteria’s dangerous impact on people and fishes. The article could be
As Jensen points out, farming and industry accounts for the vast majority of total water usage in the world (477). The increasingly scarce resource is a necessary ingredient when growing food. Technology continuously improves to make it easier for farmers to grow crops while using less water. Scientists at the University of Georgia utilize what they term “variable rate irrigation” to let farmers automate the current systems of irrigation to water only the crops that need it (Gies). This is an example of retrofitting current farms, but there is a new way of farming coming to cities that reuses practically all of its water and stakes claim much less acreage in the process. The future of agriculture belongs to vertical and urban farming. These types of farms reduce the use of water, chemicals (such as pesticides, herbicides and fungicides), soil and space (The Economist). These farms are so cutting edge that they are mostly in the experimental stages. Firms like Famgro farms are testing “stackable” farming systems that can scale with demand, even further reducing waste. Famgro’s stackable farms are ideal for cityscapes where land is at a premium; furthermore, reaping the added benefit of being in close proximity to the customers that they serve. Customers will enjoy high quality, fresh produce at only a slightly
Muthyam’s article states, “conventional farming’s dependency on chemical fertilizers destroys topsoil,” (Muthyam 4) and without healthy topsoil we can never produce more antioxidants or carbon. The increased production of these elements could alleviate climate change. The human beings who feel strongly about the climate change issue would be challenged on their “Bt gene” eating habits. Muthyam makes the reader think twice about buying conventional farming products because they are contributing to the problem presented. No one likes to hear about others starving which strikes the reader when they read organic farming can feed masses. The article states “we could feed our entire population through urban agriculture alone” (Muthyam 6). She also refers to the chemicals and synthetic fertilizers as being poison, which gets people double-taking their decisions to consume these conventional products. Consumers of conventional produce wouldn’t consider eating a product if it was directly labeled as
In animal agriculture today, manure that is produced by hogs has the potential to do a lot
With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.
Such efficiency will allow for a mass amount of crop production through less water use and provide Mother Nature with enough time to restore what is used in a natural manner, thus disproving Hardin’s fear of running out of the most essential natural resource, water (Gul).
For years organic farmers and conventional farmers have feuded over which is superior. Organic farmers argue that their product is more eco-friendly because they do not use the synthetic chemicals and fertilizers conventional farmer’s use. Conventional farmers argue that their product is healthier and yields more. People tend to have stereotypes regarding the two types of farmers. Organic farmers are usually thought of as liberal, hippy, tree-huggers while conventional farmers are usually thought of as right-wing, industrialists. Obviously, some do adhere to this stereotype, but a majority of these farmers are normal, hardworking people. Although these farmers, both believe in their methods, one is no better than the other. There are advantages and disadvantages to both, but there is no true superior method of crop farming.
Growing food with Aquaponics is more efficient than growing food the traditional soil garden way. In a typical soil garden, growers end up spending hours of their time doing back breaking work on their garden, but not anymore, with Aquaponics the need for any tilling, digging, or weeding is eliminated. Aquaponics combines Aquaculture (Raising fish in tanks), and Hydroponics (Growing plants without soil). The outcome is a working system that provides plants with all the nutrients they need, while using a minimum of space, effort, water, fertilizers, and pesticides. Aquaponics allows farmers to use up to 90% less water than normal farming would use, so instead of watering your soil and having the majority of your water either lost by run off or evaporated by the sun, the water is recycled repeatedly through the system saving farmers hundreds of dollars on their monthly water bills. Also when growing with Aquaponics, much more food can be produced in a smaller space, in some cases growers have produced around twenty times the amount of produce in the same area a soil garden would. In addition, with the closed, controlled environment of the system, the need for the use of any pesticides a basically eliminated. Finally, Aquaponics enables growers to grow bigger, better and more quality produce.
One important result of school gardens is students' heightened consciousness of the agricultural and natural processes by which food comes to be available in this country and in the world. The distinction between agricultural processes and natural ones is that humans control agricultural growing while we do not control natural growth. Both types are important for children to be aware of. Children need to understand natural growing processes so th...

Dan Barber is the co-owner and executive chef at Blue Hill and Blue Hill at Stone Barns. He is an advocate for sustainable farming and speaks out against agribusiness. In his Tedtalk, “How I Fell In Love With A Fish”, Barber informs us that 90% of the fish that we eat have been wiped out of the oceans. He also explains how farms that claim to be sustainable may actually be contributing to the environmental crisis at hand. “For the past 50 years agribusiness has been adamant about feeding more people more cheaply” (Barber) but their methods are not sustainable. In fact, this model is actually very destructive.
In this paper we will look at permaculture as an ethical solution to the ecological crisis. In doing so, we will utilize many topics from the course as well as additional bodies of knowledge to aid in broadening the scope of our central theme. We will explore how permaculture can propagate itself across disciplines from ecology, urban development, social and environmental justice, consumerism, the commons, localism or bioregionalism, and sustainable food. In addition, we will analyze current case studies on permaculture and its practical applications.

Sandra Postel, on the other hand, has a different opinion than Danielle’s. She proposed that “without increasing water productivity in irrigation, major food-producing regions will not have enough water to sustain crop production”.
Dr. Dickson Despommier is the biggest proponent of Vertical Farming and is also an ecology professor at Colombia University. Dr. Dickson Despommier describes his idea “A Vertical farm, many stories high, will be situated in the heart of the world's urban centers.”(Ted Talk). According to his ted talk and his book The Vertical Farm: Feeding ourselves and the world in the 21st century, this relatively new concept of vertical farming has the potential to rebuild the world in many ways and improve the world for everybody. For example, a Vertical Farm can provide fresher produce for its community because it’s grown locally, not shipped from outside sources. Additionally, Vertical Farming is designed to use much less land and water than traditional farms as well, due to the fact the water to be used will be reclaimed water, lowering the impact on the environment. (Despommier & ted talk)
Agriculture is one of the most ancient forms of art and science that ties human development and well-being to natural resources and ecosystems. (Fritz J. Häni, 2007) Sustainable Agriculture is the production of food, fibre, plant and animal products using farming techniques that protect the environment, public health, human communities and animal welfare. (Sustainable Agriculture - The Basics, 2015) Sustainable agriculture is an integrated system of plant and animal production practices having a site – specific application that over the long term will:
