Increasing Consumption Of Animal Proteins

Improved Essays
The United Nations has projected that by 2050 the world population will reach approximately 9 billion (Food and Agriculture Organization, 2009, para. 2). As population increases, so does the demand for food resources. Since only a small percentage of the world population is vegetarians, animal proteins remain an important source for fulfilling basic nutritional needs. In addition to increasing population growth, Van Huis (2012) states that the recent economic bubble in developing countries in Asia may trigger an increasing consumption of meat (p. 564). However, the current level of livestock production will not sustain the future demands for animal protein due to the limited availability of agricultural lands and the unsustainable agricultural …show more content…
Muller and Krawinkel (2013) state, “Iron and zinc deficiencies are widespread in developing countries, especially in children and women of reproductive age: Approximately 2 billion people are deficient in zinc and 1 billion have iron-deficiency anemia” (cited in Van Huis, p. 571). As a result, consuming insects may appropriately address this issue because insects contain these micronutrients, iron and zinc. Additionally, Gordon states that consuming silkworm caterpillars satisfies an individual’s daily need of not only zinc and iron, but also other micronutrients such as copper, thiamin, and riboflavin (cited in Gahukar, 2011, p. 131). Thus, consuming the highly nutritious insects can provide health benefits by preventing people from suffering micronutrient deficiency …show more content…
Dossey (2013) states that almost one third of the lands on Earth are used for raising livestock (para. 1). In order to feed 9 billion population by 2050, Food and Agriculture Organization (FAO) (2009) predicts that the current level of agricultural output needs to be increased by 70 percent (para. 6). Even though the number used in the FAO’s report represents the whole food production, the prospect of expanding agricultural lands for raising livestock is included in the data. Since insects generally thrive in tight places, less land is required for insects rearing. Having studied the relationships between land use and yield products from animal, Oonincx and de Boer (2012) conclude that mealworms use only 18 m2 to yield one kilogram of animal protein, whereas milk needs at least 33 m2, chicken needs at least 41 m2, pork needs at least 46 m2, and beef needs at least 142 m2 for a kilogram of animal product (p. 3). Since land availability is limited, insects rearing can hopefully decelerate the agricultural expansion for livestock

    By the year 2050 the world’s population will surpass 9 billion. To accommodate the new populace the world will have to double its food production (Tzotzos 5). Primary growth will occur in the urban areas, creating more pollution and leaving less usable land for food production. Genetically modified organisms (GMO) are the solution to feed the growing population because they require less land, less chemicals, more crop yields per acre, and can be altered to be more nutritious with medicinal uses. However the use of these new sciences are being fought in legislation and even banned in countries all throughout Europe.…

    Two billion tonnes is the number that represents the amount of food that is wasted per year on the planet. At the same time, some countries have faced a serious aliment crisis as consequence of the poverty and hunger. By 2075, the world population can reach 9.5 billion people (Institution of Mechanical Engineers, 2013), so, the increase of food production is important to combat that issue. However, before that, food loss reduction is essential in order to avoid excessive costs and save money for governments and companies. All food processing, from the harvest of crops to their arrival on supermarket, involves many stages that can minimize its wastage.…

    A vegetarian diet take 3 times as much land which is 3/16 but to eat the way we do with meat,dairy and eggs it takes 18 times more land. This is because you can produce 37,000 lbs of vegetables on 1 1/2 acres, and only 375 lbs of meat on that same amount of land. If you switched to a complete vegan diet you could save 1100 gallons of water, 45lbs of grain, 30 sq. ft of forest, ten pounds of co2 and 1 animal’s life per…

    This was to maximise usage of the pasture available. Lamb sales were nearing 3300 this year and weighed an average of 16.5 kg per lamb. This is on the smaller side of prime lamb sales in the North Island (which average at approximately 17.5 kg per lamb) but they are sold at these weights to make room for the replacement stock units in order to better enhance their performance. The average stock unit produced approximately 4kg of wool, resulting in a total of 19,000 kg of wool produced over the year. Beef cattle (mainly cull cows and dry heifers) were predominantly sold in March.…

    GMOs, or genetically modified organisms, are organisms which have been genetically altered using other genes of bacterials to help them grow faster and last longer. Genetically modified foods haven 't been around long enough for us to know the long term effects so we shouldn 't rely on them as much as we do and should be cautious with the GMOs we eat everyday. Today, the consumption of GMOs for the average american is everyday. Almost 80 percent of foods at our local market contain any type of GMOs. For us to eat them everyday and not know the affects it has on our bodies is scary.…

    “According to the United Nations (UN) Food and Agriculture Organization, worldwide consumption of meat has increased from 23 kilograms to 42 kilograms per-capita between 1961 and 2009.” (Stoll-Kleemann 2015, p. 2). American diets have changed dramatically in recent years with increases of corn, meat and dairy in their diets. The government promotes the consumption of these surplus foods, lowering their costs and making them easily available. Thanks to the subsidies, the products produced from industrial farms are cheaper than foods produced by other means. The trend of over consumption reflects itself in American culture with large serving sizes and excess caloric…

    If GM maize crops were replaced with non-GMO equivalents, then the world would need to dedicate significantly more land to the cultivation of maize to compensate for the lost productivity. The possibility that this change will occur is doubtful. In the short term, it might be possible for more land to be used for agriculture. However, avoiding GMOs is inconceivable in the long term as the population will continue to increase exponentially. The land needed to support that population without GMOs will inevitably…

    If this trend continues – alongside the expanding population – it will become increasingly difficult for people to get a stable food source, putting more pressure on food security as a whole. More than half of all the animal-source food globally, are produced by 70% of rural, small scale, farmers who depend on the livestock for their income (MacMillian 2014). This will create an issue for food security as the in the 21st century animal agriculture there is a much higher demand for animal protein products, globally. This will continue to increase as the population continues to expand. With more mouths to feed, there will need to be a rethink on how food is distributed and a rethinking in animal science (Future of Animal Science Research 2015).…

    If the US Market fails, Whole Foods can suffer a major impact economically. • Although Whole Foods distinguished themselves from the competition by delivering great service and having a large inventory of organic foods, their prices are higher than their competitors. • Whole Foods have a limited network of suppliers who are farmers located near their stores. If the farmers whom they perform business have and increase in cultivating or suffer an impact from weather conditions, this could cause an increase in prices resulting in consumers paying higher prices for goods.

    According to the Food and Agriculture Organization (FAO) of the United Nations, demand for food, fuel, and fibre will increase by 70% by the year 2050. With an ever growing population a large amount of human beings share a hunger for one common thing- meat. According to statista.com there are approximately 979.64 million head of cattle worldwide! Uruguay, New Zealand, Argentina, Brazil and Australia have larger population of cattle than they do of humans. This massive population of livestock is causing serious environmental risks that are being too easily overlooked.…
