The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
The biggest threat caused by GM foods is that they can have harmful effects on the human body. It is believed that consumption of these genetically engineered foods can cause the development of diseases which are immune to antibiotics.
GMO seeds can cost up to $150 a bag more than regular seeds. The market for non-GMO foods has grown from $1.3 billion in 2011 to $3.1 billion in 2013, partially because some Asian and European countries don't want GMO seeds.
Looking at data from 2009 to 2016, the researchers found that organic and non-GMO foods in all four categories had higher prices compared to conventional foods. Organic ice cream was over 60% more expensive than conventional ice cream. Apparently that marketing is nonetheless effective in commanding higher prices.
List of Disadvantages of GMOs
- They would make plants that leave unwanted residual effects to remain in the soil for a long period of time.
- They can pose a threat to the insects that are important to the ecosystem.
- They can produce more weeds and can threaten the lives of animals.
- They threaten crop diversity.
Cons of GMO Crop Farming
- Cross-Pollination. The out crossing of GM crops to non-GM crops or related wild type species and the adventitious mixing of GM and non-GM crops has led to a variety of issues.
- Pest Resistance.
- Human Health.
- Environment.
- The Economy.
- Productivity.
For example, GM crops could impact food availability by providing seeds which are resistant to adverse climate conditions; have an effect on food access by increasing farmers' incomes; and, under the same food utilization conditions, bio-fortified crops could increase the nutritional status of households worldwide.
Overall, GMOs allow us to reduce the amount of energy and inputs (resources used in farm production, including fertilizer, pesticides and herbicides) we use. And by saving our crops from pests and weeds, we're able to increase the amount of food we produce per acre. That's critical for our ever-growing population.
The current food biotechnology debate illustrates the serious conflict between two groups: 1) Agri-biotech investors and their affiliated scientists who consider agricultural biotechnology as a solution to food shortage, the scarcity of environmental resources and weeds and pests infestations; and 2) independent
Review. Ethical arguments relevant to the use of GM crops. Five sets of ethical concerns have been raised about GM crops: potential harm to human health; potential damage to the environment; negative impact on traditional farming practice; excessive corporate dominance; and the 'unnaturalness' of the technology.
GMO crops have significantly increased crop yields and simultaneously decreased pesticide use. By doing these two things combined, we are producing more food with less inputs. Decreased use of pesticides, means less pesticide production demand and also less energy use on the farmers' end, too.
GMO crops are often genetically modified to improve food quality (i.e. appearance or nutrition) and increase the plant's resistance to pests, herbicides, or changes in weather. The bacterium then invades the plant and inserts the DNA into the plant's genome.
The reduction of losses by pests, viruses and weeds that compete for soil nutrients, together with savings in phytosanitary products and fuel, indirectly increase the final yield when compared with conventional crops.
More than 93 percent of the corn and soy planted in the United States is genetically modified in some way.
One way to reduce hunger is to grow certain genetically modified (GM) foods. These foods are a safe, healthy way to combat hunger and keep groceries affordable. Common GM crops are pest-resistant corn and soybeans. Crops can also be engineered to be drought-tolerant or resistant to certain viruses.
The genetic engineering of plants and animals is looming as one of the greatest and most intractable environmental challenges of the 21st Century. Currently, up to 92% of U.S. corn is genetically engineered (GE), as are 94% of soybeans and 94% of cotton [1] (cottonseed oil is often used in food products).
Sorensen is right: Milk is not genetically engineered, and neither are dairy cows. Most conventional milk comes from cows given supplemental feed from genetically engineered corn and soy. “Non-GMO milk” is shorthand for milk from cows that do not consume such feed — which is also true of organic milk.
Biodiversity Loss: The use of some GM crops can have negative impacts on non-target organisms and on soil and water ecosystems. For example, the expansion of GM herbicide-tolerant corn and soy, which are twinned with herbicides, has destroyed much of the habitat of the monarch butterfly in North America.
Genetically-modified organisms (GMOs) are some of the more recent and controversial tools that have been developed. According to the companies and scientists who design new GMO crops, this new technology is harmless to humans, better for the environment, and is the only way to feed an ever-growing population [2].
These countries include Germany, France, Italy, Austria, Greece, Poland, Scotland, Northern Ireland and Belgium, among others. Also banning GMOs are Algeria and Madagascar in Africa; Turkey, Kyrgyzstan, Bhutan and Saudi Arabia in Asia; and Belize, Peru, Ecuador and Venezuela in the Americas.
As a matter of fact, genetically engineered crops directly promote an industrial and chemical-intensive model of farming harmful to people, the environment, and wildlife. Because of corporate pressure, millions like us are denied the right to know about where GMOs occur in the food chain.
