It is 2050. Alice is walking down the street as one of the privileged with a ration card. Catching a glimpse of the current New York Times newspaper, she notices the front page picture. There are thousands of families starving for a food handout with their hands reaching towards food. The desperation can be seen in their eyes, but with the current world situation there is little Alice can do. She could share her rations, but this would leave her hungry with the rest. This is because the Earth is running out of viable soil with 80 percent of the world’s land already occupied (Mendleson, 2011). In addition, by 2050 the population on Earth is projected to increase by around 3 billion people (Feldman, 2007). This brings up an interesting query of how can enough food be produced to feed everyone? Vertical Farming is a way to feed the extra billions that humans will create in the near future because it can grow bountiful produce with less pollution that traditional farming. Therefore, Vertical Farms should be implemented in at least every state.
Vertical Farming was developed by Dr. Dickson Despommier in his ecology class. The idea came about when he proposed the problem of overpopulation and minimal land available. First they thought of rooftop farming, which in a Canadian study could save around 300 million dollars, but feed less than 3 percent of a Manhattan size population (Dunn, 2011). Then Despommier and his students thought of refurbishing abandoned buildings in the city with two types of gardening processes on every floor; aeroponics and hydroponics (The Vertical Farm: The World Grows Up, 2010). Aeroponic gardening uses a nutrient rich mist, while hydroponics uses nutrient rich water to grow plants in (The Vertical Farm: The Wo...

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

Our current system of corporate-dominated, industrial-style farming might not resemble the old-fashioned farms of yore, but the modern method of raising food has been a surprisingly long time in the making. That's one of the astonishing revelations found in Christopher D. Cook's "Diet for a Dead Planet: Big Business and the Coming Food Crisis" (2004, 2006, The New Press), which explores in great detail the often unappealing, yet largely unseen, underbelly of today's food production and processing machine. While some of the material will be familiar to those who've read Michael Pollan's "The Omnivore's Dilemma" or Eric Schlosser's "Fast-Food Nation," Cook's work provides many new insights for anyone who's concerned about how and what we eat,
...struggling to earn any income at all and sometimes do not even get the opportunity to eat. Another issue that Raj Patel did not touch on is the lack of care consumers have for the farmers. It seems that consumers care about farmers about as much as the corporations do, which, in my opinion, is not a lot. When consumers only care about low prices and large corporations only care about making a profit, the farmers are left out to dry. Many consumers believe “food should be available at a bargain price, a belief that relies on labor exploitation and environmental exhaustion at multiple points along the commodity chain.” (Wright, 95) Corporations as well as consumers generally tend to be selfish and I think Raj Patel is afraid to mention this. If only these people cared a little bit more about each other I believe the hourglass of the food system will begin to even out.
As the world population grows and consumption per person increases, the demand for food is rising. To an extent, fossil fuels have made an increase in food production achievable, but the finite supply is rapidly depleting. Over the last 50 years, global food production has tripled (Mosier et al. 2004). Despite this, an estimated 870 million people were undernourished in 2010-2012 (FAO 2013) while in 2008, 5...

In earlier years, observing nature brought happiness. One look around at the Smokey Mountains in Tennessee or at Lindsey’s Rainbow Farm in Arkansas showed everything the world offered—tall grassy fields, magnificent black bears, chilly fall nights, clear streams, slimy trout, and the warmth of the sun on my face at sunset. Breathtaking sights awaited us around every corner. Nature seemed endless. Today, places such as these appear to be found less and less. With the expansion of not only civilization but also its economy, Americans slowly destroy the once symbiotic relationship between nature and community. Americans face such a difficult situation due to the way we live our lives—specifically, the way we obtain our food.
There are many problems confronting our global food system. One of them is that the food is not distributed fairly or evenly in the world. According “The Last Bite Is The World’s Food System Collapsing?” by Bee Wilson, “we are producing more food—more grain, more meat, more fruits and vegetables—than ever before, more cheaply than ever before” (Wilson, 2008). Here we are, producing more and more affordable food. However, the World Bank recently announced that thirty-three countries are still famine and hungers as the food price are climbing. Wilson stated, “despite the current food crisis, last year’s worldwide grain harvest was colossal, five per cent above the previous year’s” (Wilson, 2008). This statement support that the food is not distributed evenly. The food production actually increased but people are still in hunger and malnutrition. If the food were evenly distributed, this famine problem would’ve been not a problem. Wilson added, “the food economy has created a system in w...
“Everyday, everyone is affected by agronomy. The food you eat, the coffee you drink, the ethanol-based gas in your car, the grass on the golf course, the natural fibers of the clothing you wear-are all products of agronomy and the work of agronomists.”(Illinois State University) An agronomist even finds the best way to plant and harvest any source of food. Agronomy is a science in which an agronomist views agriculture in an integrated perspective.(Agronomy.org)
The global population in the year 2050 is expected to be nine billion and the agricultural demand is expected to double. With the current population already over seven billion people, there are hunger issues all around the world (“New” par. 1). How are we going to deal with food shortages in the future? With less land to work with, strains on the soils, and the lack of water, it is getting harder for the farmers of the world to support our growing population. These complications are making it harder for farmers to produce quality, affordable food. To help the crops grow better, farmers use fertilizers and chemical sprays to enhance growth and control the weeds. Farming in the United States is a relevant business because it supplies people with food, provides people with jobs maintaining the used equipment with the new equipment being much more expensive, and it provides research for more efficient ways on how to feed the world.
One of the most complex issues in the world today concerns human population. The number of people living off the earth’s resources and stressing its ecosystem has doubled in just forty years. In 1960 there were 3 billion of us; today there are 6 billion. We have no idea what maximum number of people the earth will support. Therefore, the very first question that comes into people’s mind is that are there enough food for all of us in the future? There is no answer for that. Food shortage has become a serious problem among many countries around the world. There are many different reasons why people are starving all over the world. The lack of economic justice and water shortages are just merely two examples out of them all.
While it is agreed, climate change will result in higher temperatures, more frequent drought conditions and more frequent severe weather events; changes in temperature, precipitation and carbon dioxide levels, are not happening uniformly (Schimmelpfenning et al, 1996). Scientist and modules of climate change disagree as to the specific effects within any given area. Even before climate change became an issue, farmers were in the position of making decisions regarding when and wha...
“ Know your farmer, know your food” goes the slogan by organic farmers to promote the consumption of locally grown food through organic farming. Subsequent to the clear distinction between organic and conventional food, there is an increase in focus towards organic farming. The “silent spring” that represents the seemingly solitary voice of the science writer Rachel Carson, 1962 ushered in the organic farming movement to counter the green revolution industrial-scale use of pesticides and fertilizers back in the 1960s. However the use of the term “organic farming” started with Lord Northbourne (aka Walter James, 4th Baron Northbourne) (Pogash, 2008), which he derived from the concept of “the farm as organism” as, explained in his book titled
