Nowadays, various methods have been developed to encounter waste problem. The two finest method are the incinerator method and "zero waste" approach. While the incinerator method is burning the waste to make it vanishes, the zero waste method is recycling the waste into something useful (Collins, J.,2002). In many aspects, environmental and economical, zero waste is more beneficial than the incinerator method. Therefore, every country should adept the zero waste method.
Actually, both incinerating and recycling need a considerable amount of energy. However, recycling process produces useful materials which can be sold to cover the cost. On the other hand, incinerating does not produce anything useful. This means the cost needed for the incinerating process have to be supplied by the government. Therefore, financially, zero waste is better.
In addition, zero waste approach also brings an enormous benefit to the environment. Although it also produces pollution, it reduces significantly the need to exploit the environment. Paper, for instance, which are made from trees, are example of a recyclable material. By recycling papers, less trees need to be cut. Incineration, on the other hand, does not bring any benefit for the environment.
However, "no tusk have no crack", one of the zero waste cutbacks is the difficulties in encouraging the society to help by separating the waste according to their type, for example, plastic from paper or organic material. Although it is hard, with perseverance this problem can be overcome.
In conclusion, despite of the difficulties to apply zero waste method, it is still better than incineration both financially and economically. Thus, every country should try to develop this method.

Port Folio 4 : Difficulties in English

It has been 12 years since I learn my first English word, and since then, almost every day, I have tried to improve my language skill. However, I have not come to the level I wish to be or, to be more precise, the level I need to be.
After those beautiful years of childhood, I have chosen Singapore to be the place to pursue my university degree. After being in Singapore for a while, I started to realize that my English is way below standard, in writing, in speaking, in reading, everything. Nevertheless, it affects me in my course at the university.
Engineering, my course, requires its student to understand various concept and to show their understanding in the exam. For me, it is quite a nightmare. I need more time to understand the concepts than I would need if I learn it in my own mother tongue. Even so, there are also some misunderstandings of what the books or lecturers really means. Despite of it, I can still overcome it with a bit of hard work. Unfortunately, the second thing I need to do, show my understanding in the exam, is far worse. This time, I could not possibly have more time to write the answers. It is also impossible to bring a dictionary for exam. Therefore, I just have to pray and hope the examiners would understand what i am trying to say in such limited language.
However, I think I know why I have such problem. I always try to translate everything I read to my language than understanding it. Of course it takes more time and causes more misunderstandings. This also happens when I write. I tend to think of something in my language and translate it. If I can not find a suitable word to translate it, I would then get into trouble.
So, the solution to my problem is to start to think in English. It requires a long time before I can master the technique. I have to change a life long habit and it cannot be easy. Surely it is going to be hard, but "impossible is nothing"(Nike,n.d.).
