The World Health Organization defines genetically modified foods (GMO) as “organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally”. It involves technology often referred to as gene technology, modern biotechnology or genetic engineering. The process allows for selective transfer of genes from one organism to another. The transfer of genes can be done between organisms of the same species or of different species. Genetic engineering has been practiced for many years. We often hear of cases where a specific gene is selected from an animal or plant and introduced into a different organism ...

Introduction

In order to fulfill the food demands of the fast growing population of the world, a faster process of producing crops with enhanced desirable traits has replaced the conventional production. Since conventional plant breeding is a time consuming affair, genetic engineering technology has been put to use for producing plants with enhanced amount of nutritional content and increased resistance to herbicides and pests. Though genetically modified or genetically engineered foods have certain benefits, in recent years a great many side effects of these foods have come to the forefront. In the wake of the health issues and environmental hazards caused by GM ...

Forty years before the their immersion in Afghanistan, America had faced a similar problem in the Vietnam jungles. They urgently needed to find a way of counteracting the enemy’s capacity to hide from weapons while living off the land. They decided to use Agent Orange, a herbicide designed to kill the forests that were sheltering the enemy. However, this decision was arguably one of the worst that were made throughout the course of the war. The herbicide proved to be a cause of cancer (cancer). Moreover, even today, children are being born with defects and illnesses as effect of the use of ...

In generic sense of the term, a "genetically modified organism" is a living organism whose genome has been altered artificially. This understanding includes all the possible ways of modifying the genetic information, from crosses method for genetic engineering tools. From a legislative point of view, a large number of countries and organizations use a more restrictive definition in reference to that specified in the Cartagena Protocol, which means "living modified organism" "any organization living with a novel combination of genetic material. " However, this definition is not universally recognized. Some countries, including the United States, do not make this use ...

Abstract

Genetically modified organisms have large impact on our environment. Although there is not much proved evidence against it but still the amount of evidence available is enough to discuss it with its implications. GMO crops affect nearly crops by gene follow which could be minimized to some extant will the help of designing separate places for different crops. GMO also effect natural cycle of nitrogen and Carbone reproduction. GMO crops could be a risk in long time that it could alter some properties in human DNA. Steps should be taken by government and other organizations to minimize its effects to ...

Genetically modified foods come from organisms whose genetic properties have changed. The foods do not occur naturally. The genetic foods stem from plants in most cases but other foods are from genetically modified microorganisms and genetically modified animals. The genetically modified crops have resistance to plant diseases and a high tolerance to herbicides. The crops have high yields compared to the naturally existing plants. Another purpose of human-made genetic recombination in food is to reduce the time taken by the plant from the time of planting to harvest.
The use of the foods arising from this genetic combination is ...

Biotechnology has had a lot success in the world over, but with an equal measure of opposition that has continued to derail its full blown application in the food production. The application of biotechnology has found its way in the genetic modification to attain high productivity by organisms as well as resistance to diseases and pests that would have otherwise derailed its potential harvest from the farm. Genetic modification is called genetic engineering where a gene from one plant is transplanted from one crop/organism to another which would otherwise have not occurred naturally. This result in a genetically modified organism (GMO) and ...

- What are GM foods?
Genetically modified foods are derived from genetic engineering of various organisms. Unlike mutagenesis which results in non-specific alterations of the DNA, genetic engineering results in precise changes to the DNA component in an organism.
The sale of GM foods commenced in 1994, and the first GM food to be sold was a tomato that was genetically engineered to ripen at a slower rate (International Food Council 125). Genetically modified foods are mainly derived from transgenic plants. These plants are derived from artificially inserting genes into them which alters their DNA composition. The inserted gene, ...

Introduction

Human activity on the natural resources causes threats to the land sustainability either directly or indirectly. This paper examines soil erosion, genetically modified grains and overpopulation as the main threats to land sustainability.

Soil erosion and how it impacts the global food supply

Soil erosion is the washing away of the earth’s topsoil by agents such as wind and rainwater, and it occurs mainly due to human activities. Agriculture is the primary cause of soil erosion. When people clear natural vegetation to create framing fields, the topsoil is exposed to erosion agents such as the wind. Deforestation is also a leading contributor of soil erosion. As people cut ...

Introduction

Genetically Modified Cotton (GM Cotton) is one in which biotechnology has been applied to come up with transgenic or altered and desirable traits such as increased pest resistance. Approximately 25 million hectares have been put under cotton around the world especially in China, India, US, and Pakistan. GM cotton has been engineered to address two major issues. The first one is ability to resist glycophosate-based herbicides and the second issue is the ability to produce a toxin that kills bollworms which is a primary destroyer of the crop (Eyhorn, 2007).
There are controversies regarding the benefits or disadvantages of ...

Water Supplies in Sun Valley, AZ

Sun Valley is located in Arizona. It is situated along interstate 40. It is 31.56 square miles. Sun Valley has different water supply options. Some of these options are groundwater, surface water and reclaimed water. Groundwater is water found beneath the ground. They are usually in rocks and pores of the soil. Sun Valley is supplied by Arizona’s water supply. Groundwaters that supply Sun Valley are aquifers and wells. Main aquifers in Arizona are stream alluvial and basins fill. Ground water can also be sourced from sedimentary rock. Basin Fills are of three type’s namely carefree formation, ...

This essay will discuss about Genetically-Modified (GM) Foods or also known as genetically-engineered or transgenic food or Genetically-Modified Organisms (GMO). GMOs are “crop plants created for human or animal consumption using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content”. Traditionally, enhancement of organisms’ genes has been done by humans through selective breeding which depends on nature . This selective breeding eventually evolved to systematic hybridization which involves the controlled transfer of genes within species and not between different species. Hybridization though ...

Introduction: A documentary film titled Genetic Roulette: The Gamble of Our Lives, declares GMO or Genetically Modified Organism food as the most dangerous threat that human beings are facing today. Likewise, a headline in Pravda newspaper criticizing the decision to broaden GMO agriculture in Russia, reads "Russians are proud to poison themselves with GM food from their own land" (Caplan, 2013). This is how notorious GMOs are known worldwide in this generation, and anti-GMO groups have been formed to get rid of them in the market. But how true is it that GMOs are killers when there are also advocates ...
