Week 12

“You know more than you think you know, just as you know less than you want to know.” – Oscar Wilde

Today is the first session of group presentations. Topics that my classmates’ groups choose are wide-ranged from e-commerce, kinetic technology, GM food to finding love online. All of these topics are elaborated in depth and in detail. Groups also put a lot of effort on their websites.

With the presentation on online love, I get a lot of new information about this interesting field. Because I have never tried any love finding online website, the presentation really helps me to understand more about the business.

Kinetic techonology brings to me a comprehensive understanding about future technology which can really bring changes to how the world will generate energy in the future.

Last but not least, the presentation on GM food also bring depth understanding to me. As I talked about GM food for my individual presentation, I can see that the group has put great effort to research on the topic and actually give me some new information about GM food. Genetically modified food is food derived from genetically modified organism which the genetic material (DNA) has been altered in a way that does not occur naturally

Crop can be genetically modified to be more nutrious, have bigger sizes or pest & insect resistant. The articles focuses on genetically modified seeds which are created to lock insecticide chemicals into the structure of plant cells to make them less attractive to the insects which want to eat them.

There are 3 main advantages of growing GM plant. First, GM crop produce higher crop yield since its gene is resistant to insect. The tradtional method of using insecticide is not as effective because insecticide is often spread unevenly around the crop field. But when insecticide chemicals are inserted in plants’ genes, it assure the effectiveness of insect resistance and therefore, the crop yield is improved. Second, GM plants help protect environment. It saves waters and also protect soil from absorbing toxic chemicals from pesticide. Moreover, growing GM plants reduces the amount of tilling that leads to soil erosion. Third, by growing insect-resistant plants, farmers do not have to dirrectly contact with pesticide which is really harmful. Having said that, people should be careful when they produce GM food to make sure that it is safe for consumption.

In conclusion, I rated this class session 9/10 because all presentations are prepared thoroughly and give me new understanding about wide ranged issues.
