what are the benefits and risks of genetically modified organisms?

The most notable GMO risks to humans are the potential development of allergens to GM related crops and toxicity from GM crops. However, studies also show GM crops have benefits including the increased nutritional value in foods.

The prevalence of GMOs in major field crops threatens the genetic diversity of our food supply. Genetic diversity helps individual species adjust to new conditions, diseases and pests, and can aid ecosystems in adapting to a changing environment or severe conditions like drought or floods.

Genetic engineering provides a quicker and more precise way to achieve the same goal, in one generation rather than twenty. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.

An oft-cited risk of GE crops is that the genetic-engineering process could cause “unnatural” changes in a plant's own naturally occurring proteins or metabolic pathways and result in the unexpected production of toxins or allergens in food (Fagan et al., 2014).

Genetically modified organism (GMO) is commonly used to describe any of these terms and vice versa: genetic modification (GM), GM seeds, biotechnology, biotech seeds, genetic engineering (GE) and transgenic crops.

There are many benefits to using genetic engineering . It is used in agriculture to do things such as, improve the yields of important economic crops, and provide insect or pest resistance. It is also used in the medical field to create insulin, which can be used for treating diabetes .

It is known that the main concerns about adverse effects of GM foods on health are the transfer of antibiotic resistance, toxicity and allergenicity. There are two issues from an allergic standpoint.

Biotechnology is used to modify organisms, genetically, the effect of which is still not known. These genetically modified organisms, including bacteria, can escape in the wild and may disturb the balance of the ecosystem. This, as a result, may hurt biodiversity.

Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security, and medical benefits to the world's growing population.

Genetic engineering is the direct manipulation of an organism's DNA using any number of methods. GMO is the genetic modification of organisms. It's been around for a while and uses imprecise methods of genetic engineering.

Genetic engineering of animals offers solutions for improving public health and enhancing quality of life. The benefits include advancing human health, enhancing food production, reducing environmental impact, optimizing animal health and welfare and production of cutting edge industrial applications.

What are genetically modified (GM) organisms and GM foods? Genetically modified organisms (GMOs) can be defined as organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination.

Genetic engineering is used by scientists to enhance or modify the characteristics of an individual organism. ... For example, genetic engineering can be used to produce plants that have a higher nutritional value or can tolerate exposure to herbicides.
