Banana or Musa acuminata, is one of the most vital staple crop in the tropical areas. It is a common food to every person especially in the Southeast Asia where there are many banana plantations like here in the Philippines. Bananas naturally grow in shady and moist regions like on marshlands and other wetlands. The plant of this fruit usually reach a peak height of 20-25 ft., bearing up to 200 number of bananas divided into clusters commonly called the “hands”. Each banana has a size of up to 12 inches in length and 2 inches in width. It is one of the largest fruit crop around the globe with an approximate amount of 58,120,898 tons produced anually. Philippines is on the fourth rank of highest production worldwide constituting 6% of world’s bananas, having India the greatest producer with 20%. (Morton, 1987)
B. Banana Peels
Using phytochemical tests in banana peels, it was shown that the peels contain reducing substances such as tannins, mucins, proteins, alkaloids, saponins and flavonnoids. Through fermentation and utilization of Vitamin C, it can produce ethanol and it shows that peels in aqueous solution is acidic as it has the said Vitamin C (Solidum, 2011, June)
Banana peels have surprisingly inventive uses including polishing things. Scientists have now added purification of drinking water contaminated with toxic metals to the list. A study in the American Chemical Society’s journal, Industrial & Engineering Chemistry Research, reports that minced banana peel performs better than an array of other water purification materials and can do so in a sustainable way. Gustavo Castro said, “I chose to work with banana peels because I have heard for a long time that we usually throw out the best part of the fruit and that most of...

In previous studies many researchers have concluded that an apple’s peel has more antioxidant content than the flesh of an apple (5). The measure of the ferric reducing power (FRAP) is one of the most employed techniques when it comes to measuring antioxidants, however, there is not agreement about neither the standard methodology nor the reference compound to express the antioxidant capacity, although Trolox or ascorbic acid are commonly recommended (3). The inc...

Brazil nuts are harvested at plantations and in the wild. Plantations are being developed in various parts of the Amazon. Fazenda Aruana is the owner of a 12,000 hectare former cattle ranch, partially converted to a Brazil Nut plantation in 1980. By January of 1990, 318,660 Brazil nut trees were planted on 3341 hectares of land. Fazenda's original intent was to plant Brazil Nut trees in a 20 by 20 meter grids and allow cattle grazing between the trees. The trees in the Aruana plantation are the result of grafting high yield clones from the region of Abufari Amazonas were Brazil nuts are know for their large fruits and seeds. As a result of fertilization from the same clones, the fruit production among clones has been low(2). Another danger in using so few clones is the ability to resist attack of disease and insects.

Canada is the country with the third most renewable freshwater, making up roughly seven per cent of the world’s renewable freshwater (The Council of Canadians, 2015, p.5). The cause for this unfortunate water crisis is found within the privatization of water and its distribution. Each province is in charge of distributing and funding for their water within the province. While the federal government provides funding for the First Nations communities and these communities are responsible for delivering the water back (White, J. P., Murphy, L., Spence, N., 2012). This type of distribution has shown to be ineffective to the First Nations community because of their poor watershed infrastructure that contain high levels of uranium (The Council of Canadians, 2015, p. 6). If the federal government funds these infrastructures, there shouldn’t be an issue with high chemical levels. Clearly, there is an
I believe that Soluri chose bananas because they are so widely known throughout our culture. Who has not seen a banana? Most people have played that game with their bananas of trying to figure out how long before they go black. Usually, it is a game of wait three days for them to turn from green to yellow; on the fourth day, have a banana for breakfast when they have finally reached to the point of golden goodness, only to come home from work on the fourth day to find the remaining bananas covered in black spots. I digress. Bananas have stood as symbols for many societal views. For the US, the banana has stood for their cultural and societal dominance over Honduras and other countries that supply the banana for consumption (3). For the Europeans however, the banana was a symbol of the "Crass popular culture of the United States shaped by both mass consumerism and

When the water comes into contact with the pyrite, the chemical reactions that take place causes the water to increase in pH which will dissolve heavy metals which stay in solution. However, when the pH levels reach a certain stage, the iron can then precipitate out, coating sediments with the characteristic yellow, red or orange colourings (D.E.P. 2, 2002; U.S.G.S.; U.S.E.P.A., 2002). The rate that A.M.D. advances is also influenced by the presence of certain bacteria (Doyle; U.S.G.S). A.M.D that has dissolved heavy metals such as copper, lead and mercury can contaminate ground and surface water. Especially at risk are mines that are located above the water table (Keller, 2000; D.E.P. 2, 2002). The sources of water that get polluted can be surface water that permeates into the mine, shallow ground water flowing through the mine or any water that comes into contact with the waste tailings produced by mines.

Bananas are number four on the list of staple crops in the world and one of the biggest profit-makers in supermarkets, making them critical for economic and global food security. Bananas have become such a common, inexpensive grocery item that people often forget where they come from and how they got here. On an average, consumption of 6.4 billion pounds of Banana annually is observed. They are tasty, cheap, and plentiful. Chances are, you will buy or eat a Banana at least once in a week. You might be surprised to know what it takes to get that delicious, cheap, yellow commodity into your hands—the price is paid by the environment. For fresh fruit and vegetables, safe indicates that the product is free from chemical residues, pests and diseases and is also nutritious (Norshamliza and Batt 2015).One Banana after lunch is invariably a regular practice to keep good bowel movement and heart diseases. Food adulteration has become common practices that the Departments of Health and Agriculture must check the practice.
