GM crops also pose a threat to wild, non-GMO and organic crops through the risk of contamination. Contamination from GM crops can occur through pollination or seed escape, and can bear a great burden on farmers. Many organic farmers spend considerable time and money maintaining their ‘organic’ title.
What are the issues of concerns of GMOs to the environment?
A major environmental concern associated with GM crops is their potential to create new weeds through out-crossing with wild relatives, or simply by persisting in the wild themselves. The potential for the above to happen is assessed prior to introduction, and is monitored after the crop is planted as well.

There are three primary areas of concern. The effect on the environment. There is the fear that certain traits of GM crops might be introduced into the wild. The effect on the human body. Antibiotic resistant bacteria are often used to mark genetically modified plant cells.
What are the concerns of genetically modified foods?
Genetically Modified Foods: Three Areas of Concern 1 The effect on the environment. There is the fear that certain traits of GM crops might be introduced into the wild. 2 The effect on the human body. Antibiotic resistant bacteria are often used to mark genetically modified plant cells. Will this trait affect the good bacteria in the human digestive tract? Are genetically modified foods one of the reasons antibiotics are not as effective at fighting certain infections as they used to be? 3 The unintended effects on the plants themselves. By adding a new protein to a plant, are we turning a nonallergenic plant into an allergenic plant which could become a health concern to consumers?
Why are canola plants genetically modified?
The cause for concern: Genetically modified plants grown on farms are given traits that will make them resistant to the effects of herbicides, pesticides and drought.
What is genetic modification?
More correctly, genetic modification is the manipulation of the DNA and RNA of a plant food source so that it will synthesize a desired protein that otherwise would not exist in that plant.
How is the viability of a seed determined?
The viability of a seed is determined by the intricate rules followed to bring good fruit. A tiny rose seed, designed for beauty and fragrance works patiently to scent. Seeds for vegetation, food, nourishment are no different; such rules when toyed with create a psychic life unfit for growth.

The modified cells are made to be antibiotic resistant while cells that did not accept the modifications will not have antibiotic resistance. An antibiotic is then introduced among the cells. Those with resistance, which also have the desired modification, survive. The rest don’t.
Can you sit at the table and refuse genetically modified foods?
Your article makes clear, that when it comes to genetically modified foods one can sit at the table and refuse!
Why are people against GMOs?
The reasons for this opposition are complex and multifaceted, but from what is articulated and communicated by those who oppose GMOs, they are based on the perception that such crops pose an unacceptable risk to both human health and the environment. Such sentiment exists even though there have been no adverse health or environmental affects from the almost four billion acres of GMO crops grown since their introduction in 1996. Several National Research Council committees and European Commissions (as well as joint commissions) have concluded that with the extensive scientific inquiry into the safety issues surrounding the adoption of GM crops, genetic engineering using biotechnology is no different from conventional breeding in terms of unintended consequences to the environment or animal and human health. 33 The European Commission funded more 50 research programs from 2001–2010 to address concerns regarding the use of GM crops to reach this same determination. 34 Nicolia et al. 24 constructed a database of 1,783 scientific original research papers, reviews, relevant opinion articles, and reports published between 2002 and October of 2010 on GMO safety issues, and reviewed the contents to generate a comprehensive overview of the accumulated knowledge. The overall conclusion of this mammoth undertaking was that “the scientific research conducted so far has not detected any significant hazards directly connected with the use of GM crops.
What is the challenge of GM crops?
To meet the challenge of improving yields requires a constant commitment to generating a steady supply of improved cultivars and lines for all major crops. Conventional breeding cannot keep pace with what is required; to meet the targets biotechnology and the production of genetically-modified (GM) crops is filling the gap. However, there are still concerns as to the safety of GM crops for human consumption and the environment. In this review I explore the need for GM crops, the way they are produced, and their impact and safety.
What Are GMOs?
The term Genetically-Modified Organism is amorphous and somewhat imprecise. All of our crops and livestock are GMOs in that their genetics have been manipulated and designed by man over the last 10,000 years or more. This has occurred to such an extent that most barely resemble their wild progenitors. The majority could not compete or survive long outside of an agricultural setting. The FAO and the European Commission define a GMO, and the products thereof, as being plants or animals that are produced through techniques in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination. Although this is a closer description of what is meant in the general usage of the term GMO, it would also encompass several crops that have long been accepted as conventional, e.g., Triticale. Triticale is a grain crop commonly used in bread and pasta that was developed to offer a more nutritious food source (higher protein and low gluten). It is totally “man-made.” It was first developed in the laboratory in 1884 by crossing wheat with rye to form a sterile hybrid which would not survive in nature. To produce the crop, fertility had to be restored, and this was achieved by chromosome doubling to form a stable polyploid plant with two copies of each of the parental genomes (rye and wheat). 15 This was achieved in the late 1930s using in vitro culture technology and treatment of embryos with the chemical colchicine, which interferes with the normal process of cell division (mitosis) to generate polyploid cells. Clearly, this is a crop that would fit the FAO definition of a GMO but it is not designated as such. Perhaps a better definition would be a modification to The Cartagena Protocol 16 definition for “living modified organisms,” which would then read, “Genetic Modified Organism” means any living organism that possesses a novel combination of genetic material obtained through the use of modern biotechnology.
How long has GM been around?
It has been thirty years since the first genetically engineered plants were generated, and it has been eighteen years since the first introduction of a transgenic crop into U.S. agriculture. Since their emergence the acreage planted with GM crops has steadily increased such that in 2013, 433 million acres (175.2 hectares) of land were dedicated to their production, 56% of which were grown in developing countries. 28 As of 2013, a total more than four billion acres of GMA crops have been grown in 27 countries world-wide, primarily in corn, soybean and cotton, although new crops are being introduced at an increasing rate. The economic benefits of the deployment of these crops have been substantial. Mannion and Morse 29 report that on a global level, from 1996 to 2006, GM crops increased farm income by $40.7 billion, occurring in both developed (47%) and developing agricultures (53%). In the following six years (as of 2012) the global increase in farm income from GM crops had almost tripled that of the previous 10 years to reach $116 billion. 28, 30 Both studies estimate that 42% of this economic gain is derived from the increased yield associated with lower weed and pest damage as well as superior genetics. The remaining 58% accrued from a decrease in production costs (decreased herbicide and pesticide costs and a reduction in tillage). These figures indicate that the underlying agronomic benefits derived from GM crops are equally impressive: with a global yield increase of 377 million tons from 1996 to 2012. In 2012 the increase in yield attributed to GM crops for the U.S. was 47 million tons. 28, 30 Brooks and Barfoot 30 estimate that to attain an equal yield increase to that delivered by GM crops between 1996 and 2012, an additional 303 million acres (123 million hectares) of conventional crops would have been required. As James 28 postulates that to attain this extra land industrial nations would have to use marginal lands that are generally characterized by poor soils (requiring substantial inputs such as fertilizer and irrigation) and developing countries would primarily target tropical forests. Certainly such an added conversion of land to agricultural purposes would have serious ecological and environmental impacts regardless of what part of the world it is acquired.
How does GM affect biodiversity?
The adoption of GM herbicide tolerant crops does alter the biodiversity of plant populations (weeds) in agricultural ecosystems and some of the insects and other organisms that rely upon them but this is related to weed management and herbicide use not the GM crop. Alterations in biodiversity also occur in conventional agriculture where weed management strategies are employed. 48 Nevertheless there is great deal of evidence that the adoption of GM herbicide tolerant crops has had a beneficial impact on the environment. The conversion of natural habitat and ecosystems to urban development and agriculture is clearly the most detrimental aspect of human activity as it relates to environmental impact and loss of biodiversity. As yields increase with the adoption of GM crops, as discussed previously, the need to dedicate land for agriculture decreases. Apart from the reduced conversion of land to agricultural use the emergence of GM herbicide tolerant crops has accelerated and enabled the adoption of conservative tillage (no-till and reduced-till) practices. 30, 45, 48 Such practices enhance soil quality, reduce water run-off, conserves nutrients, increases water infiltration, and contributes to a reduction in greenhouse gases.
What is the future of GM?
The future is very promising for GM technologies to enhance our efforts to meet the future global needs for food , feed and fiber in a sustainable and responsible way. Conventional breeding methods, especially with the advent of genome level technologies, that are designed to both generate and exploit genetic variation in order to isolate effective alleles (variants) of genes that generate yield increases, disease resistance, pest resistance etc., also clearly play a role in this effort. Organic farming practices also have a place at the global table 63 where such practices make sense. Agriculture is a diverse endeavor, and if we are to be successful we need to embrace that diversity.
Is GM crop production good?
GM crop production is a vital tool in the “agricultural toolbox” and along with advances in the development of the new genomics based genetic technologies that improve conventional crop production it may be realistic to expect to meet the aforementioned lofty goals. Organic crop production technologies, although generally delivering lower yields than conventional crops, 32 have an important role in yield improvement and stability efforts in areas where these technologies are optimal. To abandon any one of these efforts would be unwise and potentially catastrophic, especially without sound scientific reason, as agricultural production systems are complex and changing, more so now than ever before, as global climate change alters the “farming landscape.”
