Summary on Carbon Trading and Sequestration

Environmental issues have always been a concern for everyone since its impacts can be very serious if not properly dealt with. Instead of using the more traditional ways of using threats to solve all these issues, more cost effective methods are been sought after nowadays.
A good illustration will be over the topic of the upsurge of carbon dioxide emissions. When present in excess, carbon dioxide tends to shift from its original aim of providing warmth to increasing global temperature. This is primarily due to the burning of fossil fuels as well as selfish acts of humans. In response to these, governments and environmental organizations have come out with numerous policies to control these emissions.
Two of these are carbon trading and carbon sequestration. For carbon sequestration, it basically means storing carbon dioxide through natural sinks or artificial means. The two main concerns cost and effectiveness of it, vary across different methods and location of storage. Terrestrial areas, underground geologic formation and ocean are three of the more ideal storage places. However, some questionable effectiveness and efficiency still exist in some of these places. Although all these methods are still in their mature stages, there are great chances that these technological breakthroughs can offer us solutions to curb the environmental problems.
Nevertheless, several positive measures have been carried out globally as well. Carbon trading is one such ways and it is effective in managing emissions as it enables sectors all around the world to trade with each other, preferably with those that can distribute their resources most cost effectively. Major corporations and private sectors have also gathered together to discuss and listen to projects pertaining to carbon emissions.
In conclusion, all these basic carbon storage methods are good while waiting for the upcoming of the more effective carbon sequestration policies.

W5T2- Common Grammar Mistake

Having a good grasp in the basics of grammar is crucial in improving English. Although educational institutions have been imparting these to us since young, several errors still appear in our essays. One of the most common errors that I make would be the simple and progressive verb forms. For the simple tenses, they can be further separated into the present, past or future time frames. All these dicate complete actions that occur only for a very short interval. Generally, the simple past tense is used to express facts or habits that occur very frequently. For instance, ice melts at zero degrees celsius. Next, simple past usually has "-ed" added behind the main verb and it is used to show past events. As for the simple future tense, it can varies in two forms, either with "will" or "be and going to" (Berlitz grammar handbook, 2004). Both are used when we predict something will happen. Next, we move on to progressive tense and it consists of "be" and "-ing" to the main verb. Simple progressive tense talks about something that is happening now. As for past progressive, it differs from simple past as it is used to talk about a continuing action that stetches over a past interval. Lastly, the two forms of the future progressive are the same as its simple tense but with the addition of the auxiliary be and "-ing" to the verb. It is used to show actions that are continuing in the future. To end this, although this may look easy, it still require some time and effort to master it.

Exercises: (State whether the following sentences are used with the
correct verb forms.)
1) Mr Leong usually took the first bus from his house to Clementi.
2) Our physics tutor is going to give us a surprise test this Tuesday.
3) The government invests more on the area of education in the
next few years since the people are Singapore's main valuable
resources.
4) Sam reads his maths lecture notes when I saw him a moment ago.
5) Jonny is going on vacation with his family this coming December.
