CHAPTER 1 INTRODUCTION 1.1 Nanotechnology Historical background of nanotechnology : (Feynman,1961; Drexler,2004; Ochekpe et al., 2009) Nanotechnology can be defined as the technology at the scale of one-billionth of a metre. The matter posses unique properties with nano scale of 1-100 nanometres (nm) size. The large surface area to volume ratio is the key element that is exhibited by the nano material and thus leaded to a variety of manipulations, diversifications and useful applications
Agrochemicals and pesticides present significant part of the agricultural sector. Agro-industry plays an important role in the country economy. Chemicals are used in a wide variety of products and play an important role in the world economy. They are constituents of materials, are used in preparations and products and are embedded in complex physical systems. While chemicals are a significant contributor to national economies, sound chemical management across the life cycle - from extraction to disposal

Over the past decades Nanoscience and nanotechnology is a springing up field of research interspersing material science and bionanoscience. Nanotechnology is an expanding area use to deal with materials in nano dimensions. Nanotechnology is the study and application of small object which can be used across all fields such as chemistry, biology, physics, material science and engineering. As the name indicates nano means a billionth or 10-9 unit. Its size range usually from 1-100nm (Nair et al., 2010)
of discussion in today's society. Oppositions of GMOs believe that GE (genetically engineered) crops are a serious threat to the health and wellness of human beings. However, GMOs are beneficial to society because they allow for a reduction of agrochemicals, insecticides and pesticides, on crops. In addition, GE crops allow farmers to increase the crop harvest, which will increase profits and boost the economy. Lastly, in regard to health, GMO crops actually have higher nutrient levels, which is a
change through their output of greenhouse gas emissions and carbon footprints. These are caused by the activities that agriculture engages with such as breeding of livestock, ploughing of fields, deforestation, and the use of pesticides and other agrochemicals. Climate change affects countries differently, mainly due to their ability to adapt and their geographical location. Canada and Russia benefit from the changes in climate while Sudan and Bangladesh are affected negatively, struggling to adapt.
Of those 19 modules 11 of them are directly related to standards regarding the environment. They concern themselves in teaching about conserving biodiversity through reducing the use of chemicals, protecting forests, preventing drift of agrochemicals to ecosystems, protecting wild animals, keeping shade trees, controlling soil erosion, maintaining soil fertility, using water rationally, keeping your water clean, preventing and dealing with accidents, and managing waste. These modules are directly
Can different types of plants prevent soil erosion? Erosion is the wearing away of land by wind and water. It can be caused by frequent and intense rain, high river levels, strong storms and fast moving streams. Erosion can also lead to a variety of environmental issues. Plants are a natural way to help prevent erosion and other environmental issues caused by erosion. There are two main types of erosion, wind erosion and water erosion. Both these types of erosion include soil detachment, soil movement
Since the sixteenth century, foreign dominance over Central and South America has been attributed to farming and plantations. Spaniards introduced the concept of plantation systems to the new world in the island of “La Española” or Hispaniola. From there, it spread through the Caribbean, eventually finding its way into Central and South American countries. Plantation systems were founded on slave labor and brutal methods of exploitation imposed by European colonists on indigenous peoples, and
global organic production have come many benefits both economically and environmentally. Organic agriculture's aim is, 'to augment ecological processes that foster plant nutrition yet conserve soil and water resources. Organic systems eliminate agrochemicals and reduce other external inputs to improve the environment and farm economics' (Pimental, et al). Organic production is not only beneficial to the population as a whole but to the small time farmers who are attempting to survive in a capitalist
For several decades, patents have been issued for the genes of various life forms including plants, animals, and segments of human DNA. Typically, gene patent holders are researchers in federal organizations, colleges, and companies; they often collect patents as a means for protecting their investment in research. The U.S. Patent and Trademark Office allows for genes to be protected as intellectual property with the intention of encouraging research and innovation, just as with any patent. However
John Soluri’s book, Banana Cultures, examines the production of bananas in the world market, “interactions among diverse and often divided people, not-so-diverse banana plants, and persistent yet unpredictable pathogen’s that formed and reformed tropical landscapes and livelihoods in export banana zones” (Soluri 5). Soluri talks about the historical entanglement of the Panama and Sigatoka pathogens and the export of bananas cultivation through agro-ecology. While the fungal pathogens infected Latin
Most grocery stores now sell food products labeled “organic” due to the increase in demand. Organic food became popular in the 1990’s and has since remained on anupward trend. Although there are more and more supermarkets stocking organic food products on their shelves, non-organic food products seem to outnumber the amount of organic food products. Organic food products are labeled with a green and brown sticker that says USDA ORGANIC. When most Americans see this label they think that what they
Introduction Rapid advancements in nanosciences and nanotechnologies in recent years have opened up new prospects for so many industrial and consumer sectors that they have been regarded as the hotbed of a new industrial revolution. The food sector, which is worth over 4 trillion US$ per annum globally, is an obvious target of these new developments. Food related applications of nanotechnologies offer a wide range of benefits to the consumer. These include a possible reduction in the use of preservatives
The widespread use of glyphosate is contaminating the environment and the food we eat stated louise henault ethier science projects manager at the david suzuki foundation. Glyphosate was created by monsanto employee john e franz in the early 1970s then introduced by monsanto in 1974 .a likely chemical to be carcinogenic to humans.causing an ever growing list of hazardous effects for example, kidney disease. There is a lot to be known about n- (phosphonomethyl) stycine also known as glyphosate. Its
Agriculture: introduction: 168 words My ISP topic is agriculture because I like science and I find farming and ranching interesting. I also wanted to find the many interesting uses of our food such as corn wheat and sometimes its not even food. Cotton and other foods can be used for clothes and some everyday needs I wanted to find out more. I don’t really know that much stuff i just know names of food and crops. I wanted to know how we harvested the crops and what we used, I wanted to know how
In United States ' history we have had many problems with child labor. What actions can be taken to stop the child labor in United States? Child labor laws has helped the children in America greatly by not having to work long hours, having a minimum wage, and the worker must be at least 16 years of age before they can work. Child labor refers to any work or activity that deprives children of their childhood and education. In effect, the activities that are detrimental to the physical and mental health
The Monsanto corporation of today is based on agricultural and in supporting farmers to the best of their ability with their mission to produce more while they are also conserving more. During the past decade, Monsanto reinvented itself from an Agrochemical company to seed and biotech company. By doing this, the Monsanto’s Company was able to lower some of the opposition into becoming stakeholders. On ethical issues such as bribery, however, the company did plead guilty to and paid the fines to
Organic food has become so popular these days, since people especially in United States are making a commitment to have a good start towards a healthier life. People often doubt whether the organic food is really healthier and more nutritious? Why does it cost so expensive? Well, first of all, the term “organic” is referring to the way agricultural products are grown and processed which later on will affected the quality of the food. In order for a product to be labeled as “organic”, they must meet
