GMOs are genetically modified organisms. This just means food products are sometimes genetically altered to better fit the needs of the consumer. These needs include longer lasting crops, seedless crops, and the size of crops. All of these needs can be reached through crossing the traits of one organism with another, to make the perfect organism for consuming.
One common GMO is the soybean. Soybeans are common in dressings, mayonnaise, fried foods, and even amenities like candles and lotions. When soybeans are being harvested, they often are very harmed by the herbicide sprayed to prevent weeds around their production. Since this was harming the production of soybeans, the Monsanto Company, a US multinational agrochemical and agricultural biotechnology corporation, decided in 1994 it was time to make a change in soybean production. They crossed genes from agrobacterium with the genes from the soybean, to produce a product that was nearly invincible to herbicides. This change in the soybean produced longer lasting soybeans that caused some GMO controversy.
PROS OF GMOS: GMOs make food better for consumption. For example, many GMOs result in larger, plumper crops or even increase their production. Also, some GMOs increase shelf life, widening the time frame people can store food. Lastly, some genetically altered foods survive hot or cold temperatures better than non-GMO foods.
CONS OF GMOS: Several GMO products have no indication on their labeling that they are genetically altered! This poses problems for individuals with food allergies, if they don't know what has been added to the food they are eating, they could get very ill. Also, consumption of GMOs have lead to instances of cancer and premature death in rats. If GMOs are harming rats, who knows what they are doing to humans! Lastly, GMO production is VERY expensive!
My personal opinion regarding GMOs:
Here is a scenario. Let's say the government decides to take something like wifi away from the public. They send agents to every house in America, and removes every piece of technology that requires any kind of wifi whatsoever. A lot of people wouldn't be to happy, right? Since lots of Americans use internet services every day, they would be greatly effected. Internet of course is not nessacary, but most people wouldn't want to live in a world without them. In my opinion, the same goes for GMOs. Since they are already very incorporated into our daily diets, most people wouldn't be too happy that the food they love would be off of the shelves. I feel, also, that if individuals are very opposed to GMOs, there are different stores that only serve non-GMO foods. It is better to alter your shopping plan than to ruin the enjoyment of certain foods for everybody.
