Senior Project Essential Questions

I feel that what I learned from other people's outlines was that we need to have structure. The way ours was laid out wasn't self explanatory, so when people read it they got very confused as to what our movie was actually about. So, we need to work to make ours more self explanatory.

My essential questions are as follows:
Where does our food come from?
What is in the food we eat?

Irrigation Research Essay

How Gardening Responsibly Can Help Our World

Overusing water is something that happens often within the garden. When these practices are adopted by others, massive amounts of water become wasted. On top of this, people will often use pesticides to help their garden grow, unaware of the widespread and dangerous effects that these chemicals are having on our environment, our food, and even us. Sometimes, the overuse of water and the misuse of pesticides can work together to make the situation even more hazardous. However, this is by no means an unsolvable problem. There are ways to responsibly garden. These responsible gardening practices are beneficial for us, the world around us, and public health.

We live in a world where water is becoming more and more valuable, as with a growing population, the demand for it becomes higher. However, we are still practicing many techniques that waste millions of gallons of water. If one waters their lawn on a hot day, they could be losing around 50% of the water from their sprinklers to evaporation. Some people also favor over watering their lawns. If, for example, someone runs their sprinkler for 2 hours, they are wasting around 500 gallons of water. These numbers are beginning to add up, and having enough clean water is starting to become a legitimate concern for the world. Unfortunately, wasting copious amounts of water is not the only thing that faulty gardening practices are doing. There is a threat that is possibly far worse.

Pesticides are often used to maintain a garden by killing off the pests within it. Pesticides present a major threat to our environment. Pesticides themselves are a poison, designed to kill certain types of organisms that might interfere with the growing of a garden. However, these pesticides will often become airborne, and then infect other organisms. Since they spread like this, they are very difficult to get rid of, and have spawned into multiple self-sustaining strains. Among the organisms these strains infect are flowers. When these plants get infected, the creatures that pollinate them die, such as bees and butterflies. As the Global Healing Center puts it, “Pesticides are a major threat to bees. The systemic poisoning of flowers has killed scores of bees. We're simply losing too many of them… More than 25% of the bee colonies died in winter 2006/07. That translates to a loss of tens of billions of bees. And it's estimated that this loss will negatively impact the agricultural economy to the tune of $8 to $12 billion.” These are just a few of the adverse effects that pesticides have on the world around us, which as can be seen, can also have very damaging effects on our economy.

However, that’s not all. There are major health risks associated with pesticides, as well. Some of the most deadly poisons known to man are contained in pesticides, and although regulated, the effects can still be seen. Many pesticides contain neurotoxins, which can damage brain activity. This has been known to affect the growth and development of fetuses, with a 70% increase in the chance of getting Parkinson’s disease. The risk is not only associated with the first exposure to pesticides; sometimes they build up in the body, to the point where they can become fatal. In China, an estimated 500,000 people a year are adversely affected by pesticide poisoning. Also, the production of pesticides has been known to kill. Another fact from the GHS states, “One disaster at a pesticide manufacturing plant was in Bhopal, India. The plant accidentally released 40 tons of an intermediate chemical gas, methyl isocyanate, used to produce some pesticides. In that disaster, nearly 3,000 people were killed immediately, overall approximately 15,000 deaths occurred. Today nearly 100,000 people suffer from mild to severe permanent damage as a result of that disaster.”

Wasteful water practices and pesticides, when combined, have adverse affects of their own. When someone uses pesticides on their lawn, and then over waters, those pesticides make it into our water system. This contaminates our public water supply, and also gets into our ocean, and into the fish that we eat. This process ensures that we cannot escape from these poisons. They go into the air we breathe, the water we drink, and the food we eat – no matter whether the food was farmed or fished.

There are a few solutions to all of this. Firstly, people can stop using pesticides on their lawn. This would stop adding more pesticides to our system, and allow the current levels to decline. We would then begin to see lower levels in all sorts of diseases, such as cancer or Parkinson’s. Next, people can stop over watering. A lawn only needs water that goes down a few centimeters to get to the root. If puddles start collecting on top, then the lawn is being over watered. People should try to water in the morning or evening if it is going to be a hot day, so that the water won’t be lost to evaporation. EarthEasy suggests; “Mulch will slow evaporation of moisture while discouraging weed growth. Adding 2 - 4 inches of organic material such as compost or bark mulch will increase the ability of the soil to retain moisture. Press the mulch down around the drip line of each plant to form a slight depression which will prevent or minimize water runoff.” Finally, there is a solution that can hit 2 birds with one stone: drip irrigation. This is a highly efficient watering system, which only releases single drops of water at a time in multiple areas of a lawn or garden. This ensures that there won’t be any excessive water used, and almost none of it will be lost to evaporation. It is known to conserve both money and water, and help the plants grow better, as well. Also, if one chooses to use pesticides on their garden – although it is not ideal – there is no runoff with drip irrigation, which ensures that the pesticides won’t enter the water system. No matter which of the aforementioned options one might choose, these recommended gardening practices would all be beneficial to our standard of living, our way of life, and our world.

Farmer In Chief Socratic Seminar

I felt the reading we had; Farmer In Chief - was a very educational and interesting piece. More than any of the facts, figures, and ideas mentioned in the article though, what I liked best was the tone of the article. As I mentioned in the Socratic seminar, the author did not take the stance that he had a point to make, and he would make the reader believe what he felt. Rather, he had a certain way that he felt about the issue, with certain ideas as to why things are the way they are, and how to fix them, and he provided his evidence that led him to these conclusions.

We spent much of our discussion hashing out the pros and cons of the plan suggested in the article, and whether or not it would be worth it to attempt to follow this advice. I believe our end conclusion was that this was a road we needed to head down, because the path we are on will not lead us anywhere good. However, we cannot expect to reach any desired results - such as an abundant supply of organic food for the world, drastically less reliance on fossil fuels, and an increase in public health and awareness - anytime soon. As the article stated, this is a process that would take at least 5 decades.

However, after reading this article, and hashing it out in the discussion in class, I can hardly find any reason to dislike or disapprove of this reading and what it suggests. Despite the cost, difficulty, and long time frame, I believe that this intricate, multiphase process of changing the way the world does food is not only beneficial, but necessary.

Guest Speaker

Note: Internet was down Wednesday night. So I posted this at school on thursday.

I found what our guest speaker had to say to be quite interesting. The thing that got to me is that he is just a normal person like us, but he was able to do something pretty interesting and extraordinary, simply because he had the drive to. The idea of a veggie bus is very intriguing, and so is the fact that he was motivated to do this.

What I have learned from his visit to our classroom is all that you really need to succeed in what you want to do is really to be passionate about it. After this, knowledge on the topic, as well as what you can do to be a part of it, will follow. In order to be successful in environmental science, all I need to do is focus on the parts that I find interesting, and really fixate on them. Once I do that, I will subsequently learn and become interested in related topics, and discover new solutions to any problems that arise - for myself or for the world that I live in.
