What are the implications of GM-technologies for animals? The source document for this Digest states: BOX 21 Genetically modified crops as animal feed Genetically modified crops, products derived from them and enzymes derived from genetically modified micro-organisms are widely used in animal feeds. The global animal feed market is estimated at some million tonnes.
GMOs and The harmful effects of gmos environment Although the global debate on GMOs has usually allied disparate groups concerned about food safety and the environment, environmental risks are perceived to differ from food safety risks in several ways.
Experience built up through decades of environmental impact studies suggests that the impact of new biological elements in ecosystems may take years or decades to be understood.
The environmental impacts of introduced GMOs can be either ecological or genetic and may include: Because these potentially adverse effects have been documented in the field with non-GMO species, and because the consequences of these effects could be serious, it is important to regulate and monitor all introductions of GMOs effectively.
Field experiments in ecology take months or years to become valid. Furthermore, current data on GMOs in the field should be viewed as location-specific, and extrapolations from laboratory or computer simulation to the field must be made cautiously.
Environmental issues and GM crops GM crops are commercially available and planted on more than 40 million hectares across six continents. These plantings represent the largest-scale experience in the introduction of GMOs into ecosystems, and they have become the focus of environmental concerns.
Activists, worried about GMOs being released into the biosphere, have destroyed test plots in at least four continents. This may show the depth of their commitment, but it also prevents anyone from learning from the data that should have been collected from those tests. The majority of the area under GM crops is planted with varieties resistant to herbicides.
These herbicides are associated with a shift towards less mechanical tillage in large-scale arable crops, which reduces primary soil erosion. Early on, weed scientists appreciated and studied the environmental consequences of introducing GM crops, especially for weed control.
Monarch caterpillar - The Monarch butterfly has generated the most detailed research into the impacts of GMOs on wild species - E.
The repeated use of one herbicide causes a shift in the weed flora because there is very high selection pressure on weeds to evolve biotypes that are resistant to the herbicides associated with transgenic plants bred to be tolerant of those herbicides.
Gene flow occurs with the spread of genes through pollen and outcrossing from herbicide-resistant crops to related weed species.
In the absence of the particular herbicide, the possession of this trait is unlikely to improve the strength of the weeds but, when the herbicide is applied, it would improve the weeds' strength and could reduce the economic benefits of herbicide resistance. The risks of gene transfers are higher in areas of origin and diversification.
Care needs to be taken to ensure that native germplasm, including weed and wild crop relatives, is not affected by the transfer of herbicide-resistant genes. Monarch butterflies and alternatives analysis of Bt maize Monarchs Danaus plexippusmigratory Lepidoptera that feed on milkweeds, are the best-known butterflies in North America.
A well-publicized study of GMOs showed that Bt maize pollen was toxic to laboratory-fed Monarch butterfly larvae. A study later collected pollen-covered milkweed plants, which were found growing naturally next to Bt maize fields.
A significantly larger proportion of Monarch butterfly larvae that fed on these field-collected plants died compared with those fed pollen-free plants.
Conventional insecticides, which are the dominant alternative for controlling pest Lepidoptera now employed in maize production in North America, also kill Monarchs and other wild butterflies. Tested alternatives within an IPPM framework include:Three Take-Aways from the NAS Study on GMOs.

New FDA . The topic of genetically modified organisms (GMOs) is a very confusing subject and is often like opening up a can of worms when brought up..
But while the topic may be hotly debated, recent studies are showing harmful effects that could convince many more to join the “nay” side.
In fact, according to this recent research, GMOs could be tampering with your DNA! 50 Harmful Effects of Genetically Modified (GM) Foods by Nathan Batalion PakAlert Press – 5 edited to restore original heading format Page 1 of 35 File: PakAlert Press_ Harmful Effects of GM alphabetnyc.com Rev.
50 HARMFUL EFFECTS OF GENETICALLY MODIFIED (GM) FOODS including bizarre GMOs,have been filed with the US Patent. GMOs have been linked to allergic and toxic reactions, dead livestock, and damage to the organs of lab animals. There has been a significant rise in disease, toxins, and an alteration in the DNA of humans (mutations that can pass to future generations), since the rise of GMOs.
The prospect of GMOs intermingling with non-GMOs and introducing engineered genes into the environment is a frightening possibility that seems like it could be straight out of a sci-fi movie. There are also dangers when it comes to loss of biodiversity and the impact on populations of other species due to environmental changes.
GMO stands for “Genetically Modified Organism,” and the phrase refers to plants or animals that have been genetically engineered to produce a specific set of characteristics.
