After watching the video “An Inconvenient truth” by Al Gore, I think it is the time to wake up and make corrections for our father’s mistakes. If we don’t act fast enough, our next generations would have to bear the consequences.
One of the main reasons for the global warming is the uncontrolled emission of carbon dioxide, and CFC gases. In order to cut down the emission rate, our government needs to solve this major problem. In Vietnam, where almost everyone owns a motorbike, the government is trying to encourage its people to use more public transports. More buses are being operated as well as more campaigns to promote the new mean of transport. The infrastructures are implemented as well to accommodate these changes. The government not only increases the taxes on vehicles but also increase the operating fee for individual vehicles. For the time being, we feel somehow annoyed by these new policies, because the taxes on vehicle was already one the highest in the region for such a poor country. However, if we look into the long term, these necessary policies mean to keep the emission of carbon dioxides as low as possible, as vehicles produce as much as 30% of the total emission.
Besides these policies, Vietnam government also reduces the process of deforestation. More new materials are encouraged to replace wood in construction. Farmers could earn more money from the government by protecting and planning the wood than harvesting them. Protecting the wood could help in reducing the level of carbon dioxides as well as prevent more natural calamities such as mug flood.
Another important policy that helps to reduce the global warming is the 3Rs, that are Reuse, Recycle, and Reduce. Each household is encouraged to classify their waste into separate bins. Further more, there is no tax for the recycling businesses, in order to attract more investors to this business.
Next, heavy industries are reallocated far away from the crowed cites. Each factory is encouraged to implement ISO 14000, a standard system to control polluted gases and wastewater before releasing them into the surrounding area.
By all the recent policy, we hope to cut down to emission of carbon dioxides and slow down to global warming process. These tasks are not only belonged to the government but also to each one of us. We all have a role to play in this big picture, as the Earth is ours.

1st Entry
After reading the article “The expanding world of engineers” by professor Seeram Ramakrishna, as an engineer student, I feel proud of the discipline I’ve chosen. The modern engineer is now playing an important role in various disciplines due to their ability to work systematically.
As an engineer, we have to adapt to the new working environment, new challenges, which require engineer to have broad knowledge to come up with appropriate solutions. In order to achieve anything, firstly, we need passion. In my opinion, it’s the most important one. Passion would give us the urge to learn, to observe on variety of phenomenon. By attending lectures, we are able to obtain the knowledge of analyzing the problem and step-by-step construction of the solution. Further more during laboratory sessions, we should seize the opportunity to gain more hand-on experiences because that’s the most effective way of learning. An experiment is a good practice for us to work systematically from setting up the experiment to collecting and analyzing the data. Another important skill is observing, a good observer can simply understand any process or procedure quickly and holistically. That would eventually help an engineer to build up the skill to analyze complex information.
In order to solve more complex problems effectively, engineer should build up a strong foundation on their respective field. Next, we would try to gain board knowledge by taking initiative to venture into different fields. We need to open up our social network, meet more people from various disciplines to exchange experiences. By joining more collaborative projects, engineer would be able to expose themselves to more techniques of problem solving. Lastly, we should keep a positive thinking, willing to work and to face tomorrow’s challenges.
