Public Transportation an Effective Way to Reduce Pollution

Do you think it is better for government to spend money developing public transportation or developing new kinds of cars? Why or why not? Give reasons for your answer and include any relevant examples from your own knowledge and experience.

Pollution are the biggest contribute in global warming which are caused by private cars on the roads. While many people argue that government should spend money for the development of alternative energy cars, I believe that government should creates effective public transportation system to reduce air pollution.

Alternative energy cars become recent invention technology today. Some developed countries converted from conventional cars to alternative energy cars to reduce pollution and decrease economy cost from car's usage. They developed alternative energy cars to reduce pollution that are caused by incomplete combustion in fuel cars but an expensive cost needs to develop this kind of vehicle. By using alternative energy cars such as Electric vehicles (EVs) and Plug-in hybrid electric vehicles (PHEVs), the emission that produces less than diesel cars. EVs and PHEVs running only on electricity have zero tailpipe emissions, but emissions may be produced by the conventional vehicles. A research from US Department of Energy's Clean Cities said that in conventional vehicles produces 87 lb CO2 emissions and spent $12.10 for its cost, whereas electric cars produces 54 lb CO2 and spent the cost about $3.74.

However, public transportation become important part in the country's strip. Government as stakeholder in a country has a big responsibility to provide comfortable transportation for their citizen. By developing public transportation it will reduce cars' usage and traffic jam, because many passengers will choose comfortable public transportation rather than driving their own cars. Automobile emissions contribute to smog, global warming and public health problems. The scientist examined that cars account for about 50 percent of air pollution nationwide. Public n vehicles emit fewer pollutants than single-passenger automobiles. For example, buses emit 80 percent less carbon monoxide than a car. Rail emits almost none. I believe that if the government spend money to improve their public vehicles use alternative energy, it will very useful to reduce pollution.

To sum up, the government should concern to improve eco-friendly transportation for their citizen rather than develop electric cars. By developing public transportation it believes that will reduce pollution more effective than electric cars.

Writing Feedback / Foreign Language Foster Student's Abilities [3]

Nowadays students have to learn foreign language in their schools since their first grade in order to prepare their future. While I agree with this methods, I do believe that there is drawbacks in this methods.

Globalization effect decreased the knowledge about mother-language. Students in the first grade should be given knowledge about their first language so as to they care with their language as literature as well. It is very important for student to preserve their language and familiarize at using their first language in daily life. Beside, by forcing students to study foreign language also cause psychological effect. Young pupils cannot be pressured to always study in some subjects because their life is playing. If they overladen with subject in school such as studying foreign language, it is possible will pressure their psychological effect and make them lazy to study.

Students nowadays are pressured to ready in facing globalization era. Language has important role in this situation. As a result, many schools include subject of foreign language in their curriculum to ease their student at learn foreign languages such as English and Arabic. A research in UK found that more than 2 billion students learn English over the world. Most of them are Chinese. Student in China should learn English since third grade of elementary schools. It makes students in China have big opportunities to get best education and jobs.

Moreover, by learning foreign language can stimulate students in academic achievement. A research in 2003 by Carolyn Taylor showed that a third the foreign language students in the present study significantly outperformed students monolingual peers after sustained enrollment. These findings underscore the positive effect continued foreign language study has on academic achievement and helps substantiate the view. In addition, a researcher in Yale University said that bilingualism fosters the development of verbal and spatial abilities. The best grade to start learning foreign language for student is in their fourth grade.

All in all, studying of foreign language today become important subject in every elementary school as preparation to get big opportunities in student's education and jobs in the future. Besides, studying foreign language can stimulate verbal and spatial abilities for student as well although students have to learn their first language at first.
