The Extinction of Bananas

The Rise of Opium
Opium use in China began as a recreational event for the upper class, but it was eaten for the most part, which was a less harmful use of the drug. Eventually sailors brought tobacco into China, and introduced the activity of smoking tobacco to the Chinese. Smoking became such a big hit in China that the Emperor decided to ban it to prevent it from damaging the population. With the ban on tobacco smoking, the Chinese decided to begin smoking opium in its place. They did not know that smoking opium was a much more effective way to intake the drug. This led to a higher rate of addiction, and essentially created the path to the world's use of opium derived drugs. The opium trade spread around the world, and many people became hooked, mostly to the derivative of it known as heroin. Eventually, two of the main players in the trade triangle that had the most control had fall outs within their government, and the trade was disrupted. This led to the shift of the trade to Afghanistan, and the rise to their power in opium trade.

One of the Problems With Cattle
Consumers that helped the act become reformed wanted the healthiest meat possible, while still protecting the animals. Advertising and marketing for cattle pushed the labels of “organic” and “free-range” farms on these caring consumers. The advertisements lead consumers to believe that the products with these labels mean the meat is healthier, because it is hormone free. Also, consumers believe it is better for the animals since they are raised on a “free-range” farm. Neither of these beliefs are actually true. However, the cattle companies are doing nothing to correct the image of “healthier” or “safer” meat, because they are making a large profit.

Need for Pesticides
The breed of banana popularized in the United States is derived from a line of bananas first pioneered by a Jamaican man named Jean Pouyat in 1837. This breed line has the Gros Michel rhizome in it, which is a genetically inherited component. Due to the genetic need for bananas to be related in order to inherit this component, the line of bananas has very little gene variation. The lack of gene variation in a plant does not allow it to evolve along with its predators, thus making it more susceptible to diseases and pests. Since this same gene pool for bananas has been in circulation for over a hundred years, these plants are susceptible to a variety of diseases that have perfected the art of attacking them, the main two of which are Panama disease and Sigatoka disease. This low gene variation is significant because it causes them to need extra human care. In order for the bananas to survive these diseases, they must be sprayed with pesticides by workers. These pesticides can cause harm to the workers if they are not properly equipped with protection. If it were not for the popularization of a particular banana breed, then there would be no need for workers to be put in harm’s way to spray the plants, because the bananas would be allowed to naturally co-evolve with their pests.

Week 5: Pulling Teeth
Having taken this course multiple times, I could write a good deal about what I like and do not like about it. But I will restrict myself to just a few.
Firstly, I am very, very glad that they have allowed the option of taking this course online. From the first time I took this course, I thought it should be available online rather than in class as so much outside time is necessary to complete the course. I took a writing course at my community college online and it was the greatest thing ever because we only met once at the start, during the middle, and at the end of the semester. In saying that I am I glad this course is online, I do not agree that we should have a mandatory meeting every week. I think that still slightly defeats the purpose of having the course online. I think that if students want help figuring things out, they should just be able to contact the instructor individually and keep open communication with their fellow students. I also believe that instructors’ office hours can add to that help; students can visit their instructor if they need to.
Secondly, we’ve been told as students that a letter grade is what it is regardless of the symbols that follow it (e.g. an A is technically still an A whether it has a + or – or nothing after it). Therefore, I think it is superfluous that the prerequisite grade for this course in 39B or any equivalent course is a B or better, not B- or better. I received B- in 39B, and was not concerning by grades in my coursework, but my attendance. As with this course, I felt in 39B my time was better used outside the classroom doing my work on my time and not having to be involved with redundant discussions about a website that we did not have to use every function for, and could explore and ask questions about on our own. Also, I did not (and still do not) feel it necessary to take every class to review every bit of the syllabus and everything to do with the entire course when that time could be used to work on our assignments.
Also, on a more personal level, I unfortunately have not been interested in any of the reading that I have been given. It took me a few times to read the initial book I was required (Nickel and Dimed) before I retained any information from it. I eventually bought the book-on-CD to help me. And I was really ready at this point to take the course for one last time, and then I was given another book that I again was uninterested in. I could go on for a lot longer, but the bottom line is this course has been like pulling teeth without being sedated--for me anyway.
