...112-22 General Purpose: To Pursuade Specific Purpose: To motivate those who consume conventional produce to choose organic food ------------------------------------------------- Food or Fungus: Conventional vs Organic 1. Introduction- Have you ever asked yourself, how healthy your food really is? We will provide information on the subject for you. With spending money on foods, which has a great impact on the body, to helping our environment; we will be discussing the pros and cons of organic vs conventional foods. 2. Body Part 1 Pros – Organic foods can be costly but you also get what you pay for. Understandable not everyone might have the money to buy it but there are programs out there that helps in some ways such as Food stamps. This is a program that helps families that have low income with purchasing food. With Food stamps families can purchase any foods in any grocery store. People with low income that receive this can purchase organic foods. Rebuttal – However conventional foods are more affordable and easy to find. Colby College students made a chart showing that conventional foods cost less than organic foods. On their chart they showed non organic milk costing $3.76 a gallon and organic costing $7.36 a gallon which is a 94% difference in pricing. Part 2 Pros – Besides organic food being costly, it is good for the heart. Organic foods do not contain synthetic pesticides. The way to know what the product contains or how it is grown is by looking at...

...preservative characteristics. It has also been found that selenium deficiency may lead to increased susceptibility to disease and ill health. Organic And Inorganic Selenium Explained Selenium exists in two chemical forms in nature, Organic Selenium and Inorganic Selenium. Inorganic Selenium can be found in different minerals in the form of selenite, selenate and selenide as well as in metallic form. In contrast, in vegetable feed Organic Selenium is an integral part of amino acids. Therefore, in nature animals receive selenium mainly in the organic form. Research had shown that Organic Selenium is far more beneficial for us as our body absorbs and retain Organic Selenium at a better rate. Organic Selenium vs Inorganic Selenium Organic Selenium Inorganic Selenium • Exists in the form of seleno-amino acids, i.e. selenomethionine. • Exists in the form of mineral salt. • Is actively absorbed by amino acid routes. • Is passively absorbed from the small intestine. • More Organic Selenium is retained by our bodies. • Most of the unused Inorganic Selenium in our bodies is excreted. • Our tissues store Organic Selenium and hold it in reserve for times of greatest need, such as during times of stress. • Only a small amount of Inorganic Selenium finds its way into body protein. • Organic Selenium is retained by our body in useful form. • Inorganic Selenium is...

...cancer in the world. According to Australian Institute of Health and Welfare (2014), 3 out of 10 people who suffer from cancer in Australia died from skin cancer in 2010, and in 2010-2011, there were 10,457 patients with melanoma, which is one type of skin cancer, making up 1.2% of all cancer related hospitalizations in those years. There are always debates on the ability of sunscreens to prevent and protect skin from ageing and skin cancer. The purpose of this essay is to discuss the protection from ultraviolet (UV) radiation damage, with the use of sunscreen. This essay will include an overview of the different types of UV radiation and how it is responsible for skin damaging, secondly, how sunscreen works by combining organic ingredients and finally, how inorganic ingredients contribute in sunscreens. DISCUSSION UV Radiation With two of three Australians estimated to suffer from skin cancer during their lifetime, Australia remains the skin cancer capital of the world (The Australian Photobiology Testing Facility at the University of Sydney 2007). The health system in Australia spends around $232 million annually for only skin cancer (AIHW 1998). Compared to visible light, UV radiation has a shorter wavelength (figure 1) which makes it invisible to the naked eye (Epstein and Wang 2014). The ozone layer of the Earth’s atmosphere filters most of the UV radiation before it reaches the surfaces. Without the ozone layer, skin that...

...Energy and nutrients – Chapter 7 Sources of energy: light, organic, and inorganic molecules Rate of energy acquisition is limited Optimal foraging theory helps explain choice and location of food items Question: How on Earth life is being fed ? Energy use and kingdoms How energy is obtained? Who captures Bacteria the most? What is the message here? What is PAR? (next) Animals Protists Heterotrophic PhotoChemosynthetic trophic Plants Fungi 1 Energy use and kingdoms What is PAR? Photosynthetically active radiation Measured by photon flux. Photon flux – the number of photons striking 1m2/second Visible light (400-700 nanometers) carries ~45% of solar energy at sea level Three pathways for using this energy: 1. C3 (photosynthesis) – C3 plants 2. C4 – C4 plants 3. CAM (crassulacean acid metabolism) Question: What ecological consequences do these biochemical pathways of photosynthesis have? C3 vs C4 plants C4 plants use lower concentration of CO 2: - can afford to open stomata less than C 3 plants - conserve water The two pathways involve different number of carbon atoms in the initial photosynthate (3 vs 4) CAM plants combine day and night phases with C 3 pathway – very efficient water use 2 Question: Are needs for nitrogen different between plants and animals? If yes, why? Why does nitrogen take center stage? Can you get nitrogen from the air (recall 1M03)? What is it for? So, how do we get...

...Seminar Option 2 1.) Define the differences between the following terms: a) Natural Medicine vs. Biomedicine Natural Medicine is considered alternative medicine, which is any medical therapy that is not a synthetic drug or surgery. Natural medicine is the science and art of preventing, curing, or alleviating ill health by using treatment modalities in harmony with the laws of nature. Natural medicine cares for and treats individuals not disease entities. Biomedicine refers to conventional medicine. Biomedicine is based on the biological understanding of the organism. There is emphasis on disease and high technology rather than on health and individualized care. b) Plant vs. Drugs Plant is something that is grown in nature that is natural. A drug is something that is chemically processed in order to create the substance that is wanted. c) Vitamins vs. Minerals Vitamins are organic compounds that release energy from food, develop red blood cells, help in blood clotting and help in maintaining healthy skin, eye, and hair. All vitamins are required by the human body for healthy nutrition. Minerals have a denfinite chemical composition, minerals are inorganic compounds, and they help in bone and tooth formation, blood coagulation and muscle contraction. Only some minerals are required by the human body for nutrition. d) Plant Constituents vs. Accessory Nutrients Accessory nutrients are beneficial nutrients that your body either can make or, if...

The lack of management of solid wastes thus led to the Black Plague which killed half of 14th century Europe. 22 human diseases are associated to improper solid waste management. Solid wastes also have a great potential to pollute the air and water. Mining tailings from gold and silver mines will probably being spilling arsenic into the water supply forever. Materials Flow - The best way to reduce solid wastes is not to create them in the first place. Others methods include: decrease consumption of raw material and increase the rate of recovery of waste materials. Technological advances - Increased use of plastics and fast, pre3 prepared foods.

...Organic Vs. Conventional “The ultimate goal of farming is not the growing of crops, but the cultivation and the perfection of human beings” (Fukuoka 119). Agriculture is one of the most important determinants of the quality of non-urban areas, one that can create a cultural identity of an area. But despite the cultural identity it can give, farming and agriculture also provide food which is needed for all living organisms to survive. Nevertheless, the processes and methods of producing the food are split between two very different ideas: Conventional or Organic agriculture. Conventional farming describes any farming not dedicated to alternative methods. Fundamentally, conventional farming is the kind of farming which dominated the 20th century and which accounts for most farming today. In conventional farming, chemical plant protectants, chemical fertilizers and intensive mass animal farming are common. The term “conventional farming” draws its meaning from the contrast to alternative farming methods such as organic farming. Conventional farming methods date back to the Industrial Revolution, which gave birth to newly invented machinery. This new machinery began producing goods with greater efficiency and output, which had previously been made by hand. It was also the beginning of the transformation of society, but did not overtake agriculture as quickly as it did in other areas of production, such as textiles and printing. No doubt, that was because agriculture...

...These synthetic fertilizers are “man made” inorganic compounds, that are usually derived from by-products of the petroleum industry (Gach). Commonly used synthetic fertilizers include : Ammonium Nitrate, Ammonium Phosphate, Superphosphate, and Potassium Sulfate (Gach). Each of these fertilizers are unable to be absorbed into the soil, as organic fertilizers are. Instead, only some of the fertilizer is absorbed by the plant, which leaves the remaining fertilizer to rest on the topsoil until rain washes it into the field’s waterways. Many farmers are oblivious to this, and continue to use high amounts of synthetic fertilizers on their crops because of the speed at which they cause their crops to grow. Synthetic fertilizers are not only causing harm to Ohio’s most abundant natural resource, but they are slowly depleting nutrients from fertile...

...Differences between Pharmaceutical Medicine and Natural Medicine Humans want a way of healing that works and is safe for their bodies. Though pharmaceutical and natural medicine work in different ways, the primary aim is to alleviate pain, suffering and curing diseases in humans. Both of these medicines have different underlying principles of dealing with ailments. Exploring each side, to see how they are different, or how they are the same, is the only way to answer the following questions; what is going to work best and what is safer to use? I have done some research to explore the differences and similarities so you, as the reader, can decide if natural remedies promote a longer, healthier life. Dr. Valinda Gueye (2001), discussed in an article, the safety between these two systems. Some Conventional Medicines have adverse reaction and are increasing at an exponential rate causing untold suffering and death. Natural medicine has been the mainstay of the practice of medicine since its very inception. Intervention of illness practically began with the use of natural remedies and there are examples of herbal remedies as far back as there are written records. A definitive review and close reading of medical peer-review journals, and government health statistics shows that American Medicine frequently causes more harm than good according to a group of researchers that have analyzed and combined all the published literature dealing with injuries and death caused...

...WATER AS OUR NATURAL RESOURSE There are more than 326 million trillion gallons of water on Earth. Less than 3 % of all this water is fresh water and of that amount, more than two-thirds is locked up in ice caps and glaciers. With so much water around it seems like there is enough to see us through for millions of years. But did you know that even water, which seems to be in abundance, might one day become scarce? Each time you throw something as garbage, think of where it will finally end up. Whether it is a plastic glass, your broken cell phone or the used up battery cells from your portable CD/MP3 player, they all contribute in some way to environmental pollution and are also hazardous to life. Not only are they biodegradable, but also disposing of them has their own risks as they release harmful toxins into the air and surrounding soil and ground water. All these cause water pollution .! What is water pollution? Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. Water pollution is a major global problem which requires ongoing evaluation and revision...

...Water pollution Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. Introduction Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrheal sickness every day. Some 90% of China's cities suffer from some degree of water pollution, and nearly 500 million people lack access to safe drinking water. In addition to the acute problems of water pollution in developing countries, developed countries continue to struggle with pollution problems as well. In the most recent national report on water quality in the United States, 45 percent of assessed stream miles, 47 percent of assessed lake acres, and 32 percent of assessed bays and estuarine square miles were classified as polluted...
