Genetically Enhanced Trees/plants Industrializing Technological-advancements (GETIT)

Hello, my name is J.N., and I am at my last term of my freshmen year at GCE. I took a course known as Food, which studies the science behind food through GMOs, the green revolution, and much more. We had gone to multiple field experiences, on of them being a farmers market in order to see the stance for GMOs for farmers. For this term, everyone in my class had to pick a side on whether GMOs were good or bad. I personally choose GMOs to be a good thing, mainly because of the potential it served. There were a few challenges, such as create a video that was very limited with dialogue, but there was also some success in writing the props on how GMOs are good. With that being said, I hope you enjoy my thoughts on GMOs.

Pros of GMOs from Jeimarous on Vimeo.

My father has always told me that intelligence and improving ourselves is what makes a human being good, to some extent. That if we just learn the same things, plant the same crops, or even eat the same food, we won’t have much achievement in life. That, if we didn’t advance ourselves in religion, politics, human rights and especially science, we would have been isolated. We would have still been a primate in a tree rather than living on the ground, and using fire to advance ourselves. Is it truly bad to modify food that is, in turn, truly advancing the human civilization, and feeding millions? I believe not. This is why I believe that we are doing more good than harm, and that the reason it isn’t fully gaining potential is through economic and political stances. So I will be talking about the benefits of GMOs that have helped humans by growing crops to resist climate change, can be more advanced in the future, and how it increased yields in multiple countries around the world.


First, GMOs could resist climate change such as drought. In the book Empires of Food, it states “Droughts have always been an existential problem for agricultural societies since they first appeared”pg104. It has ravaged multiple civilizations in the past. History.com states there have been droughts in Ancient Egypt, Africa, MesoAmerica, China, and Syria. Now, CO2 has made climate change so much worse where droughts are more frequent.

There is an organization known as CGIAR that is working on the climate crises, and has even successfully been able to create crops that are resistant to drought. They claim in an article “One way in which they (CGIAR) have responded successfully to the challenge is by developing varieties of major food crops that are drought tolerant or escape drought through early maturity”. Newsweek.com states that Clustered Regularly Interspaced Short Palindromic Repeats or CRISPR has also been try to achieve better crops, as well as many other organizations. In theguardian.com, it states that African countries “saw their yields increase by 20% to 30% after sowing a variety of drought-tolerant hybrids.” Another helper in withstanding droughts would be a corn known as Droughtgard, who in pri.org states “certified for sale in several other countries, including Australia, Canada, Mexico and Japan.”

Another idea on how GMOs can be useful is through its potential . newsweek.com states “food production will have to double by 2050, at which point the world population is expected to have grown from 7 billion today to well beyond 9 billion” With that in mind, people have to realize that GMOs could be an essential factor to life in the next 20 years in the human race. This could also lead to the advancement of GMOs in supply and conditions, or in other words, the second green revolution.

According to the balance.com, “There is no faster way to produce animals and plants with specific beneficial traits and, as we learn more about the genetics, many more modifications will become possible.” With hearing this, we can infer that GMOs are already advancing in agriculture in science right now. grist.org even states that researchers are looking into “This newer system (which)is called C4 photosynthesis. Researchers around the world — funded by nonprofits like the Gates Foundation — are working on creating C4 Rice and C4 Wheat. Those crops could grow 50 percent more food per acre.” Also, in Empire of Food, it talks about how FACE is working and examining rice in order to see if they could could survive higher levels of CO2. The book states that “FACE experiment as the world's most educated guess on how food would grow in the upcoming generations.”pg94 So with that in mind, I believe that GMOs can be able to support in the long run, not only in feeding people but also advancing the science in agriculture as well.

Finally, I want to talk about how GMOs have affected people today, and what are their benefits. Mainly, the biggest one would have to be the yield per acre. Alumni.berkeley.edu states “Bt corn has an estimated yield of 34 percent more in the Philippines, 11 percent in South Africa, 9 percent in Argentina and 5 to 6 percent each in the U.S. and Spain”. Not only that, but ingrist.org states “There are 7 million cotton farmers in India. Several peer reviewed studies have found that, because Bt cotton increases the amount of crop they have to sell, it raises their farm profits by as much as 50 percent, helps lift them out of poverty and reduces their risk of falling into hunger.” GMOs are helping out people by create a higher food supply that has grown both the economy, as well as allowing people to buy affordable food. Also, unlike organic, GMOs grow faster and can be able to stay in a single area without destroying forest. Grist.org states “Either we do this on the same land we have today, or we chop down forest to create farms and pastures to meet that demand, something no one wants to do.”

There are multiple arguments against GMOs, and there are at least two that I have seen.

1.Why are there GMOs when there is also hunger in the world as well? Wasn’t the whole purpose of GMOs as to help stop world hunger? 

Well, the reason there still is world hunger even with GMOs is because some countries are anti-GMO, while other times GMOs (like most wonderful things) are used only for profit.

With the expansion of GMOs, there have been multiple countries that have banned GMOs for multiple reason. The main two are that monocultures of GMOs are bad for the environment and that they are “unnatural” or are wrong. Though people could debate about it being wrong to mess with nature, the idea of GMOs being bad for the environment is false. Most of the time, it isn’t GMOs that are ruining nature, but rather the pesticides and herbicides that are being inflicted upon GMOs. In fact, scientist are already creating crops known as Bacillus thuringiensis, or bt crops that don’t need pesticides. Regardless, some countries don’t enjoy crops, and they are paying for it thanks to hunger.

In Zimbabwe, there are laws that restrict the use of GM crops, yet they have experienced multiple droughts. In the circleofblue.org, it states ““Zimbabwe’s restriction on the importation of genetically modified crops, limiting the amount of corn and other grains it can procure from South Africa,” Because of their restriction, Zimbabwe is now facing debt and hunger in their country.

2. Are GMOs healthy for people to eat?

The answer is yes. I have read countless sources, and each one of them said that GMOs are safe to eat. The one problem with GMOs is that there are added pesticides on them. Of course, scientists are working on a crop that is known as Bt crops. They don’t require pesticides because they to be “highly effective at combating pests such as European corn borer, rootworm, corn earworm, tobacco budworm, and bollworm” by harvard.edu. One of the biggest examples would be in grist.org, which states “By reducing the amount of insecticide used (which, in India, is mostly sprayed by hand) Bt cotton has also massively reduced insecticide poisoning to farm workers there — to the tune of 2.4 million cases per year.”

So with all that in mind, I do believe that GMOs aren’t just advancing in agriculture, but also in scientific research. GMOs are advancing the human society in so many ways. With that, I would have to bring back to my father's ideas on always learning, which makes us human. People around the world are dying due to the loss of crops and resources. Children in places such as Zimbabwe are going hungry and dying because of prejudice against GMOs. Even the United Nations, one of the most advanced organizations dedicated to helping countries has even stated “Nearly five million people in Zimbabwe - half of the country's rural population - will need assistance by next year”.

“GMOs have the most potential to advance human society since the development of synthetic nitrogen”
Steve Freeman, Farmer



Both these graphs represent the data founded by harvard.edu, and were adapted by Malakof D. and Stokstad E. It shows both the growth of Bt corn and the reduction of pesticides in the US. Since both are related, the two graphs are suggesting that Bt corn are making pesticides more unnecessary.


Greatest Percent Change in both graphs:

Pesticide Use vs Years: 2004-2005

0.1 kg = 2004, 0.05 kg=2005

0.05 - 0.1= -0.05/o.1= 50% kilogram decrease in pesticide

Percent of Plant arce in Bt corn: 2006-2007

2006= 40, 2007= 49 49-40=9/40= 22.5% increase of planted acres in Bt corn

The Awakening of Bread

my name is J.N, and I am a student at GCE. I take a science/mathematics class called Food, and what we do is learn the science and fundamentals of plants, cooking, and much more. We went multiple field experiences, including a cooking lesson with Mrs. Moody. What we had to do is that the class would separate and create and individual bread, then compare them to each other. There are only a few difference, mainly with the leavening agents. There were multiple struggles with the creation of bread, including working with other people, as well as time. But I am proud that I was able to finish my project. So I hope you all enjoy.

Guerrilla Gardening..... for one person



Gardening was the first evolutionary step as people went from living in the stone age as scavengers, to becoming people with civilization and buildings and such. Agriculture and gardening have affected the human race so much, yet, in this time, many people don’t even know what agriculture looks like. People just eat what they get as long as it looks good, taste good, and can be easy to find. This is why I am planning out a garden. Since I am trying to eat healthy, the best way to do it is to prepare a garden so that I can have food ready for myself and others if needed. We need to have food available to use, and not just the food that costs a dollar and uses artificial flavoring.

I decided to create a guerrilla garden, and placed it in my backyard as the perfect space. The reason I choose this is because it has a well made structure, as well as it can shine the right light onto the plants. It also has poles which could be used as poles for vines. But before I could use the space, I need to know how big the space is. Using several calculations, I have depicted the area of my porch to be about 184 feet squared.

(190 inches x 140 inches) /12= 184ft2

My plan was to get small plants, so I first had look at what small containers I had around me, and what I needed. In the end, I decided to use 4 pots, 4 buckets, 10 milk cartons (cut), two cereal containers, and two violin cases. I tried to find the volume of each container in order to find out how much soil I will need. Here are the calculations.

Violin case = 32 x Width;9 ½ x Height;3 ½ in= 1064 in 3

Bucket= pi x 52 x Height; 11 inch= 863.9 inch3

Pot= pi x 52 x Height; 7 inch= 549.7 inch 3

Cereal Container=Length;10 in x Height;6 ½ inch x Width; 6 inch = 390 inch3

Milk Carton= Length; 7 inch x Height;4 inch x Width; 6in = 1683

I then need to find the surface area in order to find out how many plants I would need to grow per foot. I got the final answer 119 feet squared as my total surface area.

(4)pots=(4) pi x 52 = (4) 78.5 inch2= 314.15 inch2
(4)buckets= (4)pi x 52 = (4) 78.5 inch2 = 314.15 inch2
(10) milk carton= (10) 7 inch x 6 inch= (10) 42 inch2 = 420 inch2
(2) violin cases=(2) 32 inch x 9.5 inch= (2) 304 inch2
(2) cereal container= (2) 7 inch x 6 inch = (2) 42 inch2= 84 inch2 +
628.3 + 420 +608+84 = 1740.3 inch2 / 122 = 12.08 ft2

There are three essential elements that are needed in the soil in order for the plant to survive and grow. These are known as nitrogen, phosphorus, and potassium. In my soil, I was able to find that I had high amounts of both nitrogen and phosphorous. The only problem was that it needed more potassium, as its levels was about 109, which is very low. In order to increase my potassium level, I needed to find out how many pounds were needed for my surface area. Apparently, it takes about 1 pound per 200 square feet in order for the potassium levels to even out, thanks to my CEC (Cation exchange capacity) being at 6. After doing several calculations, I was able to find that in order to even out everything, I would need to add about 0.06 pounds worth of potassium. How I can do this is that I will try to spread the surface area with about 0.595 pounds of compost in order to even things out.

xpd 1pd = x X 1 pd 2oox = 12ft = x=0.06pds

12ft 200 ft 12 ft 200 = 1 pd 200x ft

The number of plants in this area are small, since we have very limited space. So far, I am planning to grow onions, garlic, strawberries, carrots, tomatoes, eggplant, chile peppers, beans, mustard seed, and cherry tomatoes. Of course, if any of the nitrogen were to fail, I would add peanuts in each container as a nitrogen fixer. I will also be using companion planting, mainly with onions and garlic. What I will do is that I will plant the onions/garlic with strawberries, and cherry tomatoes, and place them all on a pole so that the vines could be able to grow. This represents the symbiotic relationship of mutualism, since each plant works for each other. I have other companion planting, but my main criteria is with the onions and garlic, since a lot of my plants are companion plants with them. One of them is carrots and onions being commensalism since one is neutral while the other is gaining benefit.

In the book “One Straw Revolution”, there were four principles or guidelines meant for natural farming. The principles were no plowing, no chemical fertilizers, no weeding by tillage or herbicides, and no dependence on chemicals. If a farmer were to follow these guidelines, then they would be considered natural farmers. I believe that, in my case, I would be able to follow the no chemical fertilizers, no weeding by herbicides, and no dependence on chemicals. The main reason I don’t follow the no plowing is I am already changing my environment by putting soil and plants where it is not natural. But I am not really trying to create a complex farm to feed others. The garden will be about feeding my family certain type of vegetables. I don’t plan on making money from any of my vegetables, but rather focus on bringing food to my family.

This is just an idea of creating a garden. If I would actually do it, then it would be great. It could be possible, only during certain seasons. I really want to do this sort of full on project, but I would first have to put some dedication into working, and some time as well. Even if I had the dedication, I wouldn’t necessarily have the time. I could possibly do it during the summer, but I feel like it would take time out of my schedule to work on trying to stabilize this garden.
