quaponics, also known as the integration of hydroponics with aquaculture, is gaining increased attention as a bio-integrated food production system. Aquaponics serves as a model of sustainable food production by fol low ing certain principles: • The waste products of one biological system serve as nutrients for a second biological system. • The integration of fish and plants results in a polyculture that increases diversity and yields multiple products. • Water is re-used through biological filtration and recirculation. • Local food production provides access to healthy foods and enhances the local economy. In aquaponics, nutrient-rich effluent from fish…...

...Factory Farming Each year millions of pigs, chickens, cows, and other mass produced animals are being abused, brutally murdered, and have even become a health hazard to human beings. Many people have turned a blind eye to this world wide epidemic so they can continue to benefit from the prices and convenience of factory farmed animals. It is true that man is the ruler over animals, but they are still living creatures that do feel pain from abuse and do still suffer when neglected. It’s bewildering to realize that we as a human race have revolutionized women’s rights, civil rights, and even going as far as protecting the environment but we continue to accept the horrific abuse of animals. It’s time for a change! Today’s farming has come a long way from what it was like forty or fifty years ago but trust me not in a positive way. Since what most people focus on now a day is money that is all they seem to care about. First lets define the word brutality according to the free dictionary on on-line brutality is the state or quality of being ruthless, cruel, harsh, or unrelenting (Brutality, 2000). Many large corporation run most of the farms today due to the economy and regular farmers not being able to afford to run let alone own a farm, factory farming has become the way to do business, despite the fact that animals are meant to graze on green pastures and drink from clean watering holes many animals are instead being confined to small cages, being brutally abused,......

Organic Farming

...Natalie Cannon Dr. Jana Davis English 1127, 029 18 November 2013 Organic Farming as a Solution to Climate Change Climate change threatens the sustainability of food production. At the same time, conventional food production threatens the sustainability of the climate. In Canada, the agricultural sector is responsible for eight percent of greenhouse gas (GHG) emissions. These emissions translate to 56.6 million metric tonnes of carbon equivalents. An extra three percent can be added to that number for “Agricultural fossil fuel and energy use” (Environmental p 111, figure 16-2). Canada needs to take responsibility and remedy emissions. Wonderfully, organic farming has the potential to mitigate climate change with sustainable food production by creating diverse farms that support farmers and soil health; and by drastically reducing GHG emissions by opting for inexpensive, low-energy, natural pesticides and fertilizers. Organic farming will mitigate climate change by protecting against soil erosion. Soil erosion is the removal of valuable topsoil sometimes caused by naturally occurring processes such as wind, rain, and drought. Often, soil erosion is caused by a combination of factors. For instance, if drought occurs topsoil becomes dry. If after the drought large amounts of wind approach that dry land in a storm, the soil will be blown away. Soil is a complex living organism filled with inorganic matter like sand, silt, and clay; and organic matter abundant with worms,......

Sustainable Farming vs Industrial Farming

...the food we consume. So, why does our food contain so many pesticides, because over 70% of it comes from Industrial Farming Operations. Today I would like to talk about multiple reasons as to why we need to move away from Industrial Farming and towards a more sustainable type of farming. What is Industrial Farming? Industrial Farming is a type of farming that maximizes production of food and profits by using excessive amounts of chemical pesticides, herbicides, and hormones that end up in what we eat, drink and breathe. What is Sustainable Farming? Sustainable Farming produces food without excessive use of pesticides, hormones, antibiotics or petroleum-based fertilizers. This practice encourages short and long term health benefits and lessens the likelihood of certain diseases. Pesticides Industrial Farming relies on the routine use of toxic pesticides applied to both crops and animals. These chemicals are known to pollute air, soil, water, and to have negative effects on human health. Sustainable farms minimize the use of pesticides and rely on alternative forms of pest control whenever possible. One such method, integrated pest management, involves carefully assessing the overall environment of a farm and using techniques including mechanical pest traps, predatory insects, and insect-repelling plants to control pests. Environment Industrial Farming causes massive topsoil erosion and aquifer depletion, undermines genetic diversity, and pollutes air, water, and......

Organic Farming

...Why the government should Subsidize Organic Farming Organic farming is a farming method focused on advancing environmental and ecosystem benefits, as opposed to the external output in farming. It promotes the health of the ecosystem, biodiversity, and the soil biological activity. Government subsidies farmer receive are aimed at promoting healthy and beneficial and responsible farming. To understand why it is crucial for the government to subsidize organic farming, it is good to evaluate the benefits that accrue from organic farming. The aim of this paper is to evaluate the gains achievable if the government was to subsidize organic farming. One of the focuses of most governments is the reduction of greenhouse gases (GHG). A UN framework for climate change is now a key focus for most governments. One way of achieving this is the subsidizing farmers to do organic farming. The aim of doing that is that, by the use of organic farming methods, the increase in greenhouse gases reduces. The essence of this is to reduce the number of energy intensive farming that have a negative impact on farming. In addition, using less energy intensive methods means more saving on the inputs and additional benefits to the farmers. This is important since, over the years, the gains and benefits for farming have reduced. That is because, of among other things, bad weather, and scares of public health. Therefore, promoting a method that will directly benefits the farmer and the environment......

Factory Farming

...Benefits of Factory Farming What are the benefits of factory farming? Factory farming or industrial agriculture involves the exploitation of animals so as to ensure profits, particularly in the dairy and meat industries. As such, engaging in this kind of farming not only offers high profits, but it also guarantees more productivity. Cheap food production: Due to the use of technology and “economies of scale,” they produce food at less cost than smaller farms, thus enabling customers to save money on food purchases (1). Efficiency: The ability to efficiently produce and distribute huge quantities of food to feed large cities (1). Employment: Factory farms provide employment to nearby communities (1). Capital: Supporters argue that factory farms do invest in the communities in which they operate (1). In today’s technology factory farming and also applying chemical products, food is produced at lower costs as compared to smaller farms. A cheaper production that benefits the producers and the consumers. Meaning producers will have better profits. Consumers can enjoy on the lower priced products. The capability of providing large amounts of food is vital in huge cities. This high efficiency will benefit the people in those particular cities ensuring they always have food. Stopping food shortages is a major factory farming benefit. The produced food product can be quickly distributed to its consumers, thus supporting better overall health. Employment of factory farming requires......

...While Farming has been Around for Centuries Anita M. Ebbinghausen DeVry University Introduction While farming has been around for centuries, the way farmers, farm has been up for debate for many decades. There have been several studies on the Industrial agricultural and equal studies about organic agriculture. According to Best, (2007) “the question as to why humans behave toward the environment is an environmentally friendly or degrading manner has been discussed in the sociological literature for more than 30 years.” (p. 451). Farmers are unable to produce their product and their land has been standing uncultivated in order to reduce the surplus of production. The long-standing concern about the social and environmental sustainability of industrial agriculture has been added to the rising question from dependency on cheap energy derived from fossil fuel. The United States is currently dependent on Industrial Agriculture, switching to Organic Agriculture will benefit the economy and help the environment. Industrial Agriculture Although the United States is currently dependent on industrial agriculture it was somewhat prosperous in accomplishing the goals of maximizing market based production and furnishing brief economic returns, it overlooked many of the unintended negative consequences. The most important recant consequence was the soil and water degradation and the loss of the farmer and the robust rural communities (Kirschenmann, 2009). It......

Farming Subsidies

...Subsidies are the Reason Americans Pay Higher Food Prices, Higher Taxes, Ending Small-Scale Farming while Destroying our Ecosystem: Michael L Ashcraft Western Governors University Background: Over 70 years ago, The Roosevelt administration announced the onset of government farm subsidies as a temporary emergency measure to help farmers earn a certain level of income. Although there have been dramatic efficiency upgrades within the farming industry, little change has been changed made regarding how the government funds farm subsidies. The basic idea of how government subsidies function, the government spends hundreds of millions of dollars to raise farmers incomes by raising the price of certain farm commodities. This increase in price encourages farmers to produce these subsidized commodities in large amounts, while encouraging consumers to buy them in small amounts (Armey, R. K., 1990). The result of producing large amounts while purchased amounts are low creates a surplus. Once a surplus occurs the government spends hundreds of millions of dollars encouraging farmers to discontinue producing the certain commodities, essentially subsidizing farmers not to farm. This policy creates great inefficiency, under the farm law passed in 1985, the Department of Agriculture has paid dairy farmers to kill 1.6 million cows and take five-year vacations from farming. Regulations have been enforced that have led to the squandering of 3 billion......

I feel the negatives greatly outshine the positives at this point in time; the wild salmon stocks are currently in danger and fish farming is taking double the amount of wild salmon to produce half the amount of farmed fish. The fish coming from the farms are dubious to say the least; they produce a chemical, disease ridden product that is not beneficial for consumption. There are many issues around the benefits of the actual fish, and what it might do to the wild if they are interbred and mixed among the wild salmon. However like everything along with the negatives come some benefits of these farms. There is a major industry with fish farming......

...Organic Farm Business Plan Freedom Farm Submitted for Commerce 492.3, University of Saskatchewan 2001 Rosalind Ball Heather Hack Murray Nelson Myles Thorpe Executive summary Introduction Organic farming in Canada, and Saskatchewan in particular, has steadily increased especially in recent years. Reasons for the increase in organic food production are: market premiums of 2 to 2.5 times the conventional market price; an expansion in the consumer sector willing to pay the higher prices demanded by organic food; an expansion of markets in the developed world where Saskatchewan farm exports traditionally are targeted; and lower input prices due to organic production. This document is a proposed business plan, with a financial model, for setting up and operating an organic grain farm in Saskatchewan. The business is new, and is named Freedom Farm. Financial performance is projected for a ten-year period from 2002 to 2012. To sell organic produce at premium, Freedom Farm will obtain organic creditation from the Organic Crop Improvement Association (OCIA). The mission statement of Freedom farm is: To provide quality organic produce to suit customer demand while maintaining soil fertility and crop productivity. Operations Plan The proposal is for the establishment of a new organic grain production business in Kipling, South East Saskatchewan. The proposed business is a sole......

...producing an economic benefit or only a cost. The costs for monitoring soil and regularly changing plants are to be considered, but are not the most expensive costs to take into account. The biggest financial challenge for organic farming is education (Juneghani et al.). It is difficult to educate farmers to be aware of the techniques needed and to educate them as to the reasons that it is better to experiment with new methods rather than continue to practice their craft in the same way that their families have done for generations. This is especially true in developing countries where the majority of people are illiterate and elderly (Juneghani et al.). For example, a study on apple farmers in a province in Iran showed that around seventy percent of the people surveyed were illiterate and that the majority of these farmers were between the ages of forty-one and fifty (Juneghani et al.). The researchers found a reluctance to new methods to be especially high amongst elders and uneducated people, who often are negatively disposed to new ideas and modern ideas of farming (Juneghani et al.). This study concluded that it would be a long, slow and resource-consuming process to educate people to use different farming methods when they are barely making a profit (Juneghani et al.). Further, the cost of paying for repeated testing of soils every few years is significant for small farmers. The tests to determine whether a crop is best suited for......

Fish Farming

...Fish farming Fish farming or pisciculture is the principal form of aquaculture, while other methods may fall under mariculture. Fish farming involves raising fish commercially in tanks or enclosures, usually for food. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species used in fish farming are carp, salmon, tilapia and catfish.[1][2] There is an increasing demand for fish and fish protein, which has resulted in widespread overfishing in wild fisheries, China holding 62 percent of the world's fish farming practice.[3] Fish farming offers fish marketers another source. However, farming carnivorous fish, such as salmon, does not always reduce pressure on wild fisheries, since carnivorous farmed fish are usually fed fishmeal and fish oil extracted from wild forage fish. The global returns for fish farming recorded by the FAO in 2008 totalled 33.8 million tonnes worth about $US 60 billion.[4] In 2005, aquaculture represented 40% of the 157.5 million tons of seafood that was produced, meaning that it has become a critical part of our world's food source even though the industry is still technically in its 'infancy' and didn't really become well known until the 1970s. Because of this rise in aquaculture, there has been a rise in the per capita availability of seafood globally within the last few decades.[5] Major categories of...

...Science states, sustainability is not just about the environment, it's also about our health as a society in ensuring that no people or areas of life suffer as a result of environmental legislation. An example of sustainability would be the development of fish farming. As the articles and video showed in this lesson, many people demands sea products. As the population grows, the demand of fish increases. Many companies main goal is to please their consumers happy, so when people are constantly buying and demanding sea products, overfishing can occur. By definition, Overfishing is when so many fish are caught that the population cannot reproduce enough to replace them. So in order to meet the desired amount of fish in the population, fish farming are created. The triple bottom line of fish farming is influenced by sustainability in more than one way. First of all, triple bottom line divides into three parts: social, environmental and financial. In the case of fish farming, as the population grows, fishing increases (social). Since overfishing is causing many environmental problems, fish farming came into place to reduce the act of fishing and by doing so, many jobs were created (financial). After the creating of fish farming, laws were also developed, such as those who limit the amount of power boats and wild fishing (environment)....

Factory Farming

...December 2015 Should Factory Farming Be Acceptable in Our Society? Since the past fifty years, farming operations in the United States have developed from individualized production to mass production, which is known today as factory farming. Factory farming is a method of food and fiber production which exploits animals in a confined environment (Marcus). As the demand for meat continues to increase, the modern agricultural practice of factory farming also continues to increase to meet the food consumption of humans. Factory farms consist of a large number of animals confined in small spaces to minimize operation costs; this mass production has decreased the price of meat as the factories produce an excess amount of meat to satisfy the demand. However, although Americans are fulfilled with the abundant amount of cheap meat, the practice of factory farming causes serious consequences for animals, humans, and the environment. This unhealthy practice has led to problems such as pollution, inhuman animal treatment, and human illness. Therefore, for all these reasons, many people have stated that factory farming is morally and ethically wrong. Since factory farms wield tremendous power in our society, they have become a controversial topic, with many people questioning whether they are detrimental or beneficial to our society. While opponents believe that the costs of factory farming outweigh the benefits, supporters rather believe that factory farming is needed in our current......

...packed areas, diseases were plentiful. With science constantly managing to find new discoveries, scientists concocted antibiotics specifically for these diseases in the 1940s. Society is quick to jump on somebody when they treat somebody like a piece of garbage, but they simply turn their heads when this happens to animals. Farmers had found a way to increase productivity and lower operating costs and this was by using an assembly line. Basically, a cow was not any better than an automobile coming off of the Ford assembly line. In addition to animals treated badly, factory farming is also putting local farmers out of business. The corporate Chief Executive Officers (CEO’s) only care about making money, and nothing else. Consequently, local farmers are losing everything they own, simply because they cannot compete with the corporation’s prices. With factory farming establishing a monopoly over local farming, food quality is hitting rock bottom. Since the industries have worried more about quantity as oppose to quality, livestock, poultry, and humans have been negatively affected. Beef is used in numerous foods, most of which people consume daily. Unfortunately, the life that the cows endure from the moment of birth to the moment of being served on a plate is nothing short of cruel and hellacious. As many people know, veal is a baby cow. When the calf is born, it is instantly stripped away from its mother and then placed into dark, tiny crate. In this crate, the calf is......

...Cattle Farming As now a day’s electricity is short and Sui gas is often unavailable from our economy is going backwards, in this situation we need to explore new horizons. One such horizon is cattle farming, in this business there is a lot of potential and need less resources but initially it is capital intensive, as lot goes in the initial 3-4 months. There are many combinations that we can do, we can go for e.g. Milking, Fattening or we can do both with an additive option of keeping goats and feeding them to be sold in the market as the sacrificial animal. Available land for this project is 16.5 acres. Near Riwind Road, Lahore. A shed is already there which can accommodate 100 animals. There is sufficient space for animals to drink water outside the shed. There are many trees of jamman under which we can tie up the animals in the summer season. We have collected some data regarding this business in detail we need 3-4 acres of land to grow the feed for the animals, animals can be buffalos or cows and goats. In this feed we can grow 5 full size buffalos, 5 small animals and 10tedi goats. Large animal is worth Rs.100000. Small animal worth Rs.24000 which has the weight of 2.5 mann. There will be 1 cow and 4 buffalos from which 1 will be male and the rest of them are female. In the case of Tedi goat 10 will be female and 1 will be male. For the purpose of growing feed in 4 acres of area for the animals we have to buy a tractor worth Rs. 400000, different type’s equipment......
