They are now producing variety that are high yielding , resistant to drought, insect pest and disease resistant, saline and water logged resistant, weed and pesticide tolerant and even improve the its nutritional value. Coupled with these discoveries, there are some potential risks in genetic modification (GM) in plants that are harmful both human and mother earth.
In Human, some GM products would cause allergies as a result of new unidentified proteins gene transferred into unrelated organisms (Campaign Web site) that may create new allergen that causes an allergic reaction in susceptible individuals (GMO Web site). Bernstein, et. al. (cited GMO Website) reported that allergic reactions in human occur when a normally harmless protein enters the body and stimulates an immune response to proteins. There are reports that any allergic reaction to food can be serious, even life-threatening, and leads to anaphylactic shock (Campaign Website). The consumption of GMO product will increased cancer rates from Bovine Growth Hormone (rBGH). This hormone was injected into cows in order to increase milk production and also human insulin- Like Growth Factor (IGF-1). This IGF-1 was observed to trigger breast, prostate and colon cancer based on reported studies (Environment website). Examples:
1. Gene from milk proteins into vegetables results a transgenic carrot (Food & Environment website).
2. Gene's protein from Brazil-nut into soybeans that triggered the allergenicity of some consumers as observed by the scientist at the University of Nebraska (Food & Environment Website).
3. Bacillus thuringiences (Bt) can be found in corn, potatoes and cotton caused allergic reaction to some people. It will provoke some kind of immunological allergic changes like asthma and other allergic reaction to human based on the study of Ohio crop pickers and handlers as reported in Science News, 1999 (cited Campaign Web site).
Second, through genetic modification plants were able to develop Antibiotic Resistance. Plants become resistant to antibiotics when genes that confer antibiotic resistance are inserted into GMO plant as "selectable markers" taken up from foreign genes (FAO Website). It will reduce the efficacy of certain antibiotic to fight harmful microorganism that cause a disease. GM plants will produce certain enzymes that helps degrade the antibiotics. There are reports that antibiotic-resistance genes could spread to pathogens in the body that makes antibiotics less effective (Campaign web site).The bacteria can create antibiotic resistance through natural mutation (Turtle Mountain website). Example: 1. Antibiotic transgenic tomato that acts as antibiotic at the same time it will destroy beneficial antibiotic in stomach (Campaign web site).
2. (GM) Bt corn
In addition, Dr. Mae-Wan Ho, (cited Campaign Web site) stressed that transgenic organism will enhance the potential for creating new viral and bacterial pathogens that are infectious to human being. In mice it will enters to the gut trying to infect the blood stream destroying the blood cell, spleen and liver cells. Example: Naked viral DNA.
The second major side effects of genetically modified plants are environmental destruction. Like the Development of Herbicide and
