There is no known information that indicates GMOs are easier to grown than non-GMOs.
There is no evidence that GMOs have improved food production.
Yes, but only some times some times they could be harmful
No, they do not. There are no laws that protect consumers if they do not want to eat GMOs. The consumers' only choice if they wish to avoid eating GMOs is to stop eating lots of foods that may contain GMOs.
GMOs (genetically modified food) may create allergies.
No one knows the long lasting effects of GMOs, though some say people have been eating them since 1996 and that is evidence that there are no long lasting negative effects of GMOs. Since long term studies on rats that showed serious effects of GMO consumption have been discredited, and GMO foods are not labeled, it is hard to determine what the long lasting effects of GMOs are. There is evidence, though it is not accepted as valid by some, that people who are put on a non GMO diet have improved health.
People don't hate GMOs. Those who oppose GMOs being used commercially at this point in their development are called anti-GMOers and fearmongers, among other names.
Genetic engineering can be done with animals, produce and bacteria. Organisms that undergo genetic engineering are called genetically modified organisms. Some of the earliest GMOs were bacteria and mice. Food products, glofish and zebra fish are some of the more recent GMOs.
No, they would not be required to be labeled. No foods that contain GMOs are required to be labeled as such.
It is not conclusively known if GMOs do or do not cause cancer.To this date, February 8, 2014, there is no known evidence that GMOs cause cancer. There is some anecdotal evidence that eating GMOs may cause other health issues, such as allergies and problems to the digestive tract.
Regulation of food began as early as the 1800s and food labeling regulation arose out of that. Recently, requiring GMOs to be labeled has been a major debate, mostly between consumers and companies who produce GMOs, food companies, and grocers. To this date, GMO ingredients are not required to be listed on food labels.
There are definitely concerns; how valid these concerns are is a matter of some debate.
