Did you know that some foods you eat are genetically modified?

Genetically Modified Foods

These are foods, in which the genetic material has been altered in a way that does not occur naturally. From prehistoric time plants and animals have been involved in selective breeding. Scientists first discovered that DNA can transfer between organisms in 1946. The first genetically modified plant was produced in 1983, using an antibiotic-resistant tobacco plant. 

In 1994, the transgenic Flavr Savr tomato was approved by the FDA for marketing in the US - the modification allowed the tomato to delay ripening after picking.  

Advantages Genetically Modified Foods

• Genetically modified food technology can develop crops with higher yield, with less fertilizer, less pesticides, and more nutrients.
• Decrease of maturation time of the plants, so they can be harvested sooner, stay riper longer and more often during the year. 
• Foods are more resistant and stay ripe for a longer period of time.
• Reduction in food-borne illnesses e.g.  Foods causing allergic reactions.
• Developments of new kinds of crops that can be grown at extreme climates.
• As more crops can be grown and at more places, this decreases global warming through the increase of oxygen in the environment and the decrease of carbon dioxide.
• Enhancement of the size of food.
• Less labor requirements. 
• Less factory additives needed.
• Scientific development of agriculture, health and related sciences due to the better understanding of the products. E.g. the development of new medicines.

Disadvantages Genetically Modified Foods

• Harm to other organisms. E.g. genes and their effect included in a crop may turn out to be poisonous to insects (monarch butterfly poisoned by Genetically Modified Foods corns).
• Scientists can choose which genes to manipulate, but they don't yet know where in the DNA to precisely insert these genes and they have no way of controlling gene expression. 
Genes don't work in isolation, changing a few could change the whole picture, with unpredictable results.
• Genetically modified crops cross-pollinate with nearby non-genetically modified foods plants and could create ecological problems. 
 Genetically Modified Foods technology companies patent their crops and also engineer crops so that harvested grain germs are incapable of developing.
• Since the production of engineered food involves infusing animal genes in the crops and tampering with nature, it might not be good for consumption in the long run.
• Genetically engineered food would increase the dependency of developing countries, on industrialized nations. This would result in a dominance of the world food production by a few countries. New advances may be skewed to the interests of rich countries.
• The biggest disadvantage of genetically modified food is that they have harmful effects. on the human body. The consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics.
• Possible creation of new kinds of weapons; genetic food and beverage weapons.
• Herbicide-resistant and pesticide-resistant crops could give rise to super-weeds and super-pests that would need newer, stronger chemicals to destroy them.

Conclusion

The advantages and disadvantages of genetically modified foods are numerous and is strongly dependent on the consumers’ preference and the developers’ motive. All genetically modified foods should be labelled by law, however according to many articles reviewed most popular brand fail to label their products genetically modified.

I am totally against Genetically Modified foods and by extension the companies that produce them. Some of the benefits that have been trumpeted have now been proven incorrect. The G.M. companies are all driven by greed and will continue to lie and deceive to maintain their status quo. They are introducing a terminator gene into their seed stock which prevents the saving and replanting of seeds from current crops. Seeds would continually have to be purchased from the G.M. companies thereby perpetuating their continued control and dominance over world food supply.
