To Plant or Not to Plant GMO’s, That is the Question

 

Educational Goal:

 

Identify and address the ethical issues of using and producing genetically modified grain.

 

Objectives:

 

 

Case Information:

 

You are a farmer in a drought stricken region in your country, where success depends on rain to provide moisture for the limited amount of grain crops grown.  The lack of moisture over the past few years has drastically reduced yields for all farmers in this area, with subsistence farming systems.  While you are able to make a meager profit by taking some of your harvested grain to market, the majority of the grain goes towards feeding your family and the small amount of livestock you own. 

 

Your region of the country is composed of farmable valleys surrounded by mountains on both the east and west.  The western coast is bordered by ocean, which adds to the climate diversity of this region.  The 93,952 square kilometers of land is comprised of many different ecozones ranging from desert to tropical rain forest.  The farmable valleys most resemble a temperate region where crops can be grown.  Temperatures range anywhere from 16-20°C with variable rainfall from around 700 mm to 4000 mm per year. 

 

As a farmer in the most water-deprived part of the country, you have been struggling to produce an average yielding maize crop for the past few years.  This year, during what has been predicted to be the worst year of the drought thus far, you need to plant all of your land to maize in order to provide enough food for your family and five cattle.  There is a limited supply of seed available due to the severe drought the previous years.  Unlike most years, area farmers will have to find outside sources for seed instead of using their own saved seed stock.   

 

With the start of the production season only a few weeks away, you have been talking with your neighbor, who also farms and is facing the same situation as you.  He informs you that he has acquired a substantial amount of seed maize, enough to plant both his land and all of your land.  Curious as to how your neighbor acquired this seed, you ask him where he got it.  He explains that since maize seed is so expensive and hard to come by this year, he got more of the less expensive maize used for food from the local store.  He says that since he only has a limited amount of money, he had to trade for the rest of the seed.  Though you have no money to buy the seed, he has offered to give you the seed in exchange for a supply of cheese your family makes, a share of the meat when you butcher your calf, and labor to help in the harvesting of his crop at the end of the season. 

 

Excited at the prospect of having a seed supply, your mind begins to race thinking of all that needs to be accomplished before planting.  The seed needs to be in the ground as soon as possible in order to make good use of the growing season.  You turn to accept your neighbor’s offer, but something stops you.  You recall hearing that the maize in the stores was imported from the United States for food consumption only.  You also remember that the majority of U.S. grown maize is genetically modified (GM) hybrids.  Though there is a possibility that the maize your neighbor has is not GM, it is more likely that it is.  You also question how a hybrid from the United States would grow in your country. 

 

Due to the government regulations that state no GM crops can be grown in your country, you hesitate to accept your neighbor’s offer.  Noticing your hesitation, your neighbor explains that while he is unsure about the hybrid issue there is a chance the maize is GM which means a possibility your maize crop will have resistance to the common maize-damaging borer, a higher tolerance to drought, and a noticeable increase in the yield at harvest.      

 

Thanking your neighbor for the information and offer, you ask for a few days to think about this proposition.  As you start the long walk home, thoughts of your family and livelihood come to mind, as well as the penalties imposed by the government for planting GM grain.  At the very least your entire crop would be destroyed if discovered.  Even after the grain is harvested, if determined to be GM, the government could destroy it all.  There is also a high possibility of having to pay a large fine for planting the illegal GM material. 

 

As you start down the lane to your farmstead, you shield your face against the wind blown soil.  You turn your head and watch as your cattle forage through the picked over stems of dried grass.  The drought has affected your cropland, your livestock, and your family.  What is the best decision? 

 

 

Questions:  Use these questions to require a written paper for students individually, as a group project, or as a spring-board for in-class discussions.

 

  1. What factors should this farmer consider before accepting or declining the neighbor’s offer?
  2. What are the potential effects, positive or negative, to the environment from planting GM crops?
  3. If you were one of the government officials imposing the regulation of no GM crops, how would you defend this regulation?
  4. Putting yourself in the farmer’s position, what would you decide about planting the GM crop and why? 
  5. What role, if any, does the current drought play in this situation?  Explain. 
  6. The farmer is not concerned about actually growing the seed only the penalties involved if the government discovers it is GM.  Should he/she be worried about growing the maize on his/her farm?  If so, why?  If not, why not?  
  7. As a farmer, what are your views of growing GM maize? 
  8. As a consumer, how do you feel about eating GM maize? 

 

 

Commentary on Case Study Questions:  Discussion on possible answers and insight into the thought behind the case study questions.

 

This farmer is faced with many different issues.  Not only the ethical issue of whether to accept the seed or not, but also crop production, legal, and environmental dilemmas. 

 

The ethical issues revolve around the central theme of whether or not to plant this GM seed maize.  Should the farmer accept the neighbor’s offer?  Even though it is against the law to plant GM maize, you need to support your family.  Will the neighbor’s offer benefit your family as well? 

 

Production issues are also a concern when deciding whether to plant GM maize or not.  Though the seed is whole kernel and has been obtained for planting, there is no guarantee that the seed will indeed grow and produce a quality crop.  There are possible problems related to the fact that corn imported from the United States is a hybrid and therefore will not properly grow due to the genetics of the plant.  Also, because this seed is the offspring of a genetically modified parent plant, there is a possibility that the desired traits (drought tolerance, insect resistance, increased yield) were not passed on to the seeds obtained by the neighbor.  Is the seed adapted to grow in this climate?  Because of the drought, will there be enough water for the plants to grow?   

 

Natural maize species are currently still growing in this region of the world.  With the introduction of GM maize and the high likelihood of cross-pollination happening, the elimination of these naturally growing maize species could occur.  On the other hand, the introduction of insect and drought resistant genes into the natural population could greatly enhance the survivability of these species.
