[week 9]Plastic debate&lecture

Well, it’s hard for me to simplify what I want to prove in today’s morning debate. I’m for the viewpoint that we should fall in love with plastic. However, we human being seem to lose the right to abandon plastic. Compared with a close love in harmony, I prefer to regard this relationship as a forced marriage.

On the one hand,  I’d take examples to demonstrate the importance of plastic in the industry. In the area of chemical engineering, plastic is a huge combination which contains five main plastic-PE(polyethene), PP(polypropylene), PVC(Polyvinyl chloride), PS(polystyrene) and ABS (Acrylonitrile butadiene Styrene copolymers). All of them take a very crucial part of industry manufacture as well as our daily production. I’ve listed a chart below which I am supposed to reveal plastic’s vital position.

On the other hand, what if we give up plastic? Absolutely our agriculture will meet a fierce breakdown. I’ve done a quick interview with one of my relatives who works in the agriculture area for twenty years.

What mentioned above is just part of his agriculture career and he emphasized the importance and irreplaceability of plastic. He insisted that during recent years we could not find another perfect-function material like plastic which has totally change the ecosystem not only for human but for nature.
