There could be underlying consequences to Genetically Modified Food and/or Organisms, and we don't know what it could cause. It could cause more chances of cancer in those who consume those foods, or it could cure cancer. No one knows what its effect on the world could be. It could either be negative or positive.
These organisms are not naturally occurring in the environment so there is no real idea of how they would react if they were released or if they escaped into the environment. Genetically engineered organisms have been created by scientists in the image of naturally occurring organisms which have been studied in their own environments and which have known behaviors. When the organisms are engineered in a lab they are going to have unknown quirks and issues in the environment and should be treated as a threat.
One reason Genetically Engineered Organisms are a threat is because
they may contain allergens. Some GMOs are created by taking genetic material
from one kind of organism and splicing it into the genetic material of another.
For example, wheat could end up with peanut DNA. People who fear the spread of these “Frankenstein plants” believe that people who are allergic to peanuts could
conceivably have a deadly reaction if they ate wheat that had some elements
of peanuts in its makeup.
Genetically engineered organisms could be a very big threat to the environment. They could introduce diseases that don't exist now. They could also offset the natural balance of things. It really depends on how or why the species is being genetically engineered. It also depends on what type of species is being engineered as well.
Genetically Engineered Organisms are a threat to the environment. They may not be apparent yet but they will soon cause some issues to the environment. The problem with creating most of these organisms is the future fight off of these substances after they develop and grow. We are continuing to see both good and bad organisms.
The big fear with GMOs is something out of Resident Evil. That's probably not going to happen. But, we just don't know what can go wrong with GMOs yet. We could create super-diseases, or crops that spread uncontrollably and destroy ecosystems.
In order to feed the world we probably will eventually need GMOs that provide greater crop yields. But it is naive to assume that there are no risks from the technology. We should move slowly and only introduce crops that we know are safe.
As it stand they may not be a threat, but it is more than possible for genetically engineered organisms to become a threat. They could end up letting off bad gases for others to inhale, toxins, or even have an experiment go wrong where the scientist become in danger. Anything is possible.
Though there is the possibility of danger, the possibility of safe, clean food is a great one. As I see it, if we are safe, then we can create food sources that will help people with many issues such as hunger. If we can genetically modify food, we can also provide not just for people, but for animals like the great panda. Imagine modifying bamboo to grow in mass quantities for our beloved pandas? Not to mention corn and wheat that grows well in, say, Africa? The risk is definitely worth the reward.
No, genetically engineered organisms are not an environmental threat, because they have been modified to be better, not worse. Genetically engineered organisms have only undergone a process to be the best that they can be. This is good for society, because there can be more farming in a smaller space, which is better for the environment, not worse.
