Group1:
Group1 discussed about the advantages and disadvantages of biodiesel, a green and renewable energy that is made from soya bean. The supporting party stated that biodiesel could benefit mankind in many ways. For example, it is renewable and safe; in addition, it will not produce much pollution to the environment.
However, the opposing party argued that biodiesel was not suitable to be used in cold weather due to the fact that its high freezing point might clog the car engines. They also pointed out that biodiesel was impossible for countries such as Singapore that does not have environment condition to grow crops. The argument was rebutted by the supporting party as they argued that Singapore could buy from other counties.
Biodiesel will become a good replacement of diesel fuel if it gets support from the government and it is believed that more policies will come out regarding this issue.
Group2:
Group2 touched the topic of whether Singapore is suitable for green chemistry deployment.
The supporting party claimed that green chemistry is renewable and pollution-free. Moreover, green chemistry could be more efficiently manufactured compared to normal plastic that is used in our daily life now.
But the opposing party argued that green chemistry may be toxic to human. Also, it is a very expensive technology which will increase the cost of plastic production. In short, it will depend on Singapore government to decide whether to implement it or not.
Group3:
Group3’s discussion was about genetic engineering and whether government should allow parents to choose their baby’s gene.
The supporting party said that everyone has the right to choose what kind of baby they want to have in the future. However, the opposing party argued that every baby also has the right to decide what kind of person or what gender they want for themselves. If the parents get to decide the gene of their baby, the baby may be forced to accept something that they might not like. The supporting party rebutted by saying that gene selection could also prevent baby from having deadly diseases. The opposing party argued that other unknown disease may appear due to the change of gene. All in all, we need to be extremely cautious when it comes to genetic engineering and we must always bear in mind that we don’t want to create people, instead, we want to make people’s life become better.

Summary of two articles related to roundtable discussion
The topic assigned to us for our roundtable discussion is “Investigate the status of one climate change mitigation technology adoption and explicate why citizen groups should support, promote, or oppose such technology. “The two articles related to this issue are “Going Underground” and “Warming Signs”.
Summary
“Going underground” is written by Mark Schrope, a freelance science writer based in Florida. He discussed about the basic idea of Carbon Capture and Storage (CCS) technology and also reported on a promising new method for monitoring carbon dioxide deep underground.
CCS is considered as a clean technology which holds huge promise. It can effectively strip 80 to 90 percent of carbon dioxide emission from conventional power plants and probably will reduce one third of the global carbon dioxide if it is fully deployed around the world. However, one worry is how to make sure that the carbon dioxide captured can be safely stored under the ground.
Throughout the years, scientists have been trying and testing numerous methods to monitor the carbon dioxide underground, for example, seismic surveys and gravity measurements. Both methods have their advantages and disadvantages. After years and years of measurement, it is concluded that gravity measurement is sufficient for long-term monitoring of carbon dioxide sites. Still, gravity measurement alone cannot fully achieve the job. Other techniques like seismic is needed to ensure carbon dioxide is suitably secure.
As CCS is becoming more and more promising, the next step would be put CCS into large scale. It is believed that CCS will play a significant role in reducing carbon dioxide emission.
The second article, “Warming Signs” from Mohan Munasinghe who is the vice chair of the Intergovernmental Panel on Climate Change and chair of the Munasinghe Institute for Development in Colombo, Sri Lanka. He suggests that the ever-increasing global warming will cause a series of disastrous consequences for the planet that we are living. People from developing countries and poor countries will be mostly affected.
According to Mr. Munasinghe, people can respond by these effects in two ways, namely, adaption and mitigation. He urged developing countries to focus on adaptation whereas the rich countries to put the effort in mitigation and also to assist those poor countries. One promising approach was discussed in the article which is known as ‘sustainomics’. It has three crucial parts: making development more sustainable; balancing the social, economic and environmental dimensions of development; lastly, ensuring any discussions transcend traditional boundaries across space and time, and among academic disciplines or interest groups.
Evaluation
The first article gives a comprehensive explanation of CCS’ monitoring system which provides readers with detailed information to help them understand and clarify their doubts.
The second article analyzes the current condition of global warming and gives some advices to both developed and developing countries to ease and prevent global warming from worsening.
