There are a lot of opinions out there about GMOs – but what does the science say? Get the facts about how GMOs may impact your health, the environment, and the economy.

1.What is GMO?
A GMO, or genetically modified organism, is a plant, animal, microorganism or other organism whose genetic makeup has been modified in a laboratory using genetic engineering or transgenic technology.
This relatively new science creates unstable combinations of plant, animal, bacterial and virus genes that do not occur in nature or through traditional crossbreeding methods.
2.What are the benefits of GMO?
2.What are the benefits of GMO?
GMO foods have been proven to be more resilient to pests and pests, which means that they require less use of pesticides. In fact, a study by the National Academy of Sciences found that GMO crops have reduced pesticide use by 37%. Pesticide use not only impacts the environment, but also human health – so this is a major benefit of GMO crops.
Another benefit of GMO crops is that they can be engineered to be more nutritious. For example, Golden Rice has been genetically modified to contain high levels of Vitamin A, which is essential for human health, but not naturally present in rice. Similarly, crops can be modified to contain higher levels of essential vitamins and minerals.
Finally, GMO crops can be designed to be more drought-resistant or tolerant to other extreme weather conditions. This is important as climate change is making extreme weather conditions more common, and traditional crops are struggling to cope. By engineering crops to be more resilient, we can help farmers to maintain food production in the face of climate change.
3.What are the risks of GMO?
A major concern with GMO crops is that they may have negative impacts on human health. For example, a study conducted in 2016 found that rats that were fed a diet of GMO corn had higher levels of kidney and liver damage than rats that were not fed GMO corn (1).
Another concern is that glyphosate, a herbicide commonly used on GMO crops, may also be harmful to human health. Glyphosate has been linked to an increased risk of cancer, and a number of studies have found that people who are exposed to glyphosate have a higher risk of developing cancer (2, 3).
Finally, there is concern that GMO crops may have negative impacts on the environment. For example, one study found that the introduction of GMO crops has led to an increase in the use of pesticides and herbicides, which can be harmful to wildlife (4). There is also evidence that GMO crops can cross-pollinate with non-GMO crops, leading to the contamination of non-GMO crops with GMOs (5).
4.How does GMO impact the environment?
There is ongoing debate over the environmental impact of GMO crops. Some argue that GMO crops can help reduce the amount of chemical pesticides and herbicides used, which can be harmful to wildlife and ecosystems. Others argue that GMO crops can lead to the development of herbicide-resistant ‘superweeds’, which can in turn out compete and damage natural habitats.
5.How does GMO impact our health?
GMOs can have an impact on our health in a number of ways. For example, some GMOs are engineered to be herbicide-resistant. This means that farmers can use powerful herbicides on their crops without harming the plants. However, these herbicides can stay on the food we eat and have been linked to a number of health problems, including cancer.
Other GMOs are engineered to produce their own pesticides. These pesticides are called Bt toxins, and they’re designed to kill pests that eat the crops. However, Bt toxins can also harm humans. In one study, Indian farmers who handled Bt cotton had higher rates of skin irritation and allergies. And in another study, people who ate Bt corn had higher levels of Bt toxin in their blood.
Finally, because GMOs are new to our food supply, we don’t yet know all of the long-term effects they may have on our health. Some experts worry that consuming GMOs could cause new allergies or other unknown health problems.
6.How does GMO impact the economy?
GMOs can have a positive or negative impact on the economy, depending on how they are used. For example, crops that have been genetically modified to be pest-resistant can reduce the need for pesticides, which can save farmers money. On the other hand, GMOs can also lead to higher costs for farmers if they have to buy special seeds or equipment, or if they lose access to international markets due to GMO restrictions.
7.How does GMO impact society?
GMOs, or genetically modified organisms, are plants or animals that have been created through genetic engineering. This means that their DNA has been changed in a way that is not natural.
GMOs are used in many different products that we use every day, such as food, cosmetics, and medicine. They are also used in agriculture, for example to create plants that are resistant to herbicides or pests.
There is a lot of debate about whether GMOs are safe for human consumption or not. Some people believe that GMOs are dangerous because we do not know enough about them and their long-term effects on our health. Others believe that GMOs are safe and can be beneficial, for example by helping us to create more nutritious food.
What do you think? Do you believe that GMOs are safe or unsafe? Why?
8.How does GMO impact the future?
There are arguments for and against GMO foods. For example, some people believe that GMO foods are more likely to be nutritious and tastier than non-GMO foods. Others believe that GMO foods may be less safe to eat and could have a negative impact on the environment.
The long-term effects of GMO foods are not yet known. More research is needed to understand the potential risks and benefits of eating GMO foods.
9.What are the pros and cons of GMO?
The agriculture industry has been quick to adopt GMO technology. One of the primary reasons is that GMO crops are more resilient to herbicides and pests, which means farmers can achieve higher yields with less effort. In addition, because GMOs can be engineered to have specific traits (like a longer shelf life), they can help reduce food waste.
That said, there are some potential negatives associated with GMO crops. One is that they may increase the use of chemical pesticides and herbicides, as farmers attempt to kill off pests and weeds that are resistant to GMOs. There is also some concern that consuming GMOs could have an impact on human health, although more research is needed in this area. Finally, GMO crops could lead to the development of “superweeds” and “superbugs” that are resistant to all known herbicides and pesticides — making them very difficult to control.
10.Should we be worried about GMO?
GMOs, or “genetically modified organisms,” are plants or animals that have been created through the gene splicing techniques of biotechnology (also called genetic engineering, or GE).
This relatively new science allows DNA from one species to be artificially inserted into the genes of another species. The result is a GMO that can possess traits from both of the parent organisms.
For example, scientists can now insert a gene from a fish into a tomato plant so that the plant is better able to withstand cold temperatures.
As Marc Brazeau points out, there is no such thing as a truly “natural” food anymore: “All crops and livestock have been altered by millennia of selective breeding… What we now call GMOs are simply the latest generation of theseAge-old genetic modification methods.”
GE crops were first commercialized in the mid-1990s, and today they are grown in 26 countries. The United States grows more GE crops than any other country in the world, with soybeans, cotton, and corn being the most common. More than 90% of these crops grown in the U.S. have been engineered to be “herbicide-tolerant” (HT), meaning they can survive being sprayed with herbicides that would kill most other plants.
The other major category of GE crops are “insect-resistant” (IR), which have been genetically modified to produce toxins that kill certain insects when they try to eat the plants. The two main types of IR crops are corn and cotton.
