Dirty Secrets of China


China is one of the largest contributors to pollution and it is becoming very hard to find clean rivers there. However, one such river still exist- the Han River in China. The Green Han River Organisation is set up by a group of volunteers to protect their river from being polluted. It is very rare to find big river with good quality water like the Han River. As there is an increase in economic growth, the amount of pollution increases as well. Toxic waste products are everywhere to be seen. People living along polluted river banks are seen to water their crops with 'black' water. I'm sure the villagers are aware that these water from the river are contaminated but because of their rural settings, they might not have access to clean water and sanitation. The contaminated river bank is their main source of water.

Then there is the "A" Inc. where the workers there have been reported to be poisoned due to the long hours exposure of a chemical known as N. Hexane. This N. Hexane is a chemical used for effective cleaning of the "A" logo and screens, it reduces the time for drying up to 1 to 2 seconds but as a consequence, workers have been admitted to hospitals due to poisoning. The Apple factory is also not a big company with full length glass windows situated in business districts, but a small warehouse with little windows at the top of the walls for minimum light and air flow situated in secluded towns. Workers admitted to hospitals named a list of effects and obvious symptoms of their intoxications such as numbing of hands and difficulty to walk or run. Some, even when recovered from the poisoning, still experience aches over the body. Prolong exposure to N. Hexane can lead to breakdown in nervous systems, paralysis and et cetera. I'm sure cleaning of logos and wiping of screen isn't the key procedure in manufactring electronic devices. By using N. Hexane can indeed reduce the drying up process, but how less efficient can it be to use some other chemically more friendly products? Is cleaning of screens and logos more important than the health of employees? These people are literally giving up their health for low paying wages. But because of the increasing in population and unemployment rate, they have to secure whatever jobs they have, even if it means risking their health. In a sense, they are working to pay for their medical bills as most who are admitted can stay in hospitals for months.

Another part of rural area in China, people there, including kids recycle unwanted computer parts for a living. DCs would export their unwanted computer parts to them for "recycling", but in fact, it's just wanted thrash that they need to dispose out of the country. The people in that area would take plastic parts of unwanted electronic products to grind them to tear them apart, then wash them and it'll be ready for use- again. Because of the lack in technology nor the money to have these technologies, the people sort the different types of plastics by using cigarette fire to burn them and smell the fumes in order to sort them out. This would inevitably lead to brain damage and other health hazards like retardation. When a local Chinese was asked what does he think about this, he knew that it is bad but he simply answered “I don’t know.”

Then in the mountains/ highlands of China, lived a group of people that are also victims of pollution. There has been an increase in the number of deaths of villagers due to cancer and they blamed it on an incinerator factory that is used to incinerate biohazard medical wastes, was built near the village. Villagers reported 11 deaths of cancer within 2 years. Environmental lawyers went to pay them a visit to see what they could help. At the mountain, black fumes can be seen coming out from the incinerators and going towards the mountains. Plants along the mountains are covered in black soot. Though there had been an increase in the number of deaths of villagers due to cancer, there has been no solid evidence that the direct cause is due to the incinerator factory. A representative from the company stated that they are much more dangerous in terms of health than the people in the mountains for they are in direct contact with the incinerators and none of the workers in the company are having cancer because of that and adding that the government is planning for the villagers to move. I think that cancer has everything to do with the incinerator factory. Firstly, the number of cases increased since the factory was first built there. Secondly, though the workers have direct contact with the incinerator, but it’s the villages up on the mountains that have the direct contact with the air pollution made by them. All the fumes and smoke are drifting towards their village. Crops and plants are covered in a layer of black soot because of that and it’s the villagers that consume these crops and in turn consume the toxic gets cancer. It is unfair for the villagers to move as they have been living up in the mountains for many generations, but because of one company that contributes to pollution, they being the minority have to move.
In conclusion, at the rate China’s economy is expanding is astonishing, but in the expense of their natural environment. I feel inclined towards the quote of one member from the Green Han River Organisation, that wanting gold and silver mountains but losing green mountains and blue water. In the future, when gold can’t be eaten and silver can’t be drunk, the future generations are doomed and by that time, people will be wanting back the mountains and the seas. People are killing this natural environment for wealth, but soon, they’ll be spending even more trying to save this environment.

Tsunami: The Aftermath

Tsunami: The Aftermath is a fictional movie based on the real event of the 2004 Boxing Day Tsunami that happened on the epicentre off the west coast of Sumatra, Indonesia. The tsunami also struck Indonesia's neighbouring countries such as Sri-Lanka, Malaysia and Thailand.

The movie is based in Khao Lak, Thailand where a young couple, Ian and Susie Carter from the United Kingdom with their 6 year old daughter, Martha Carter went to Khao Lak for holiday and unfortunately met with the tsunami that made them lost their daughter. The tsunami though significantly far from Thailand as compared to Indonesia, Sri-Lanka and Malaysia is still deadly that cause hundreds and thousands of death. Part of it due to the aftermath of diseases and poor accessibility to proper healthcare. The tsunami was caused by tectonic earthquakes below the ocean. Although the speed of the tsunami slowed down over the distance travelled to the coast, but it build up in height as a result near the shallow coasts that allowed it to engulf buildings along the coastal areas, thus destroying it. The strong backwash also pulled many people out into the sea.

Than, the Thai waiter in the movie was shown to be selfless and was trying hard by his own to help the villagers and grief over those who have deceased. He was grieving over the death of his sister and his grandmother, but quickly got back to his feet when he heard faint cries of help of villagers trapped under the debris. He promised to get help asap but was unfortunately mistaken for stealing foreigners' valuables and was caught by the police officers. By the time he returned, the people he promised to help had already passed away and he was very remorseful for not being able to live up to his promise and decided to dig out their corpse and did a simple funeral for the deceased villagers to pass on. I think it is very bravely of him to face all these by himself, which to me would be a very traumatizing event that I wouldn't know what to do. But he did not leave any time for grievience and quickly got back on his feet to do what he can to survive and help others in need.

Kathy, a Thai-speaking social worker was also trying her utmost best to help those in need and also acting as a translator for those westerners to communicate with the locals in finding their lost ones.

Nick, on the contrary is depicted as a "asshole" as I feel. He was only concerned about getting the latest news for the headlines back in UK. He wasn't symphathetic towards those who have died nor did he showed any respect to the deceased; taking photos of them moments before they were cremated and wanting to send the photos over to the press for headline news. He didn't care that this would result in uproar from people from other countries for burning those unidentified corpses and would most probably cause Thailand to fall back to it third world state. Rationally speaking, I think there is a need to cremate those bodies for Thailand is a humid and warm country which causes the corpses to disintegrate at a faster rate and this may cause an outburst in disease that eventually cause those who survived from the tsunami to die due to this aftermath. But what the monks could do is to maybe take photos of those that are to be burnt so that the family members and relatives can at least identify them and bring their ashes back to their home country where they belong. Though the surving members may be furious about the cremation but this is a preventive measure from the outspread of any disease and this decision must take into consideration of the whole surviving populations and not only those who are mourning over their dead family members.

Chai, Nick's Thai reporter partner is more symphathetic towards those deceased as he himself is a Thai and as most Thai are, he might be a Buddhist. Hence, knowing the basics of respecting the dead and prayed for forgiveness for Nick's ignorance.

It was showed that Martha was never found and Susie couldn't get over the fact that their daughter is missing, blaming everything on Ian for letting go of Martha's hands. They found a young girl that looked like Martha and Susie decided to keep her to substitute for the lost of her own daughter that she could never get over with. I feel strongly for Susie for losing her one and only child, but feel that it is wrong to keep the girl. The girl's parents might be looking for her and if she takes her away, she'll never get to reconcile with her biological parents. The girl seem too traumatised to speak up which all the more isn't right to keep for she couldn't speak to say anything like yes or no to follow Susie.

The movie also showed the relief efforts from international aid were slow in saving people, but restructuring plans were quick to rebuild new resorts over the disaster scene. It showed the different types of people during a disaster. Some like Than and Kathy would help those in need while people like Ellen and Nick are only concerned about their own interets and benefits. As well as those looters who would go to these disaster-struck places to steal people's valuables.

2004 Boxing Day tsunami, happened 2 or 3 days after I came back from a cruise trip on Starcruise Virgo to Phuket Thailand, therefore I felt deeply for the people there, Thinking about all of them while we tried to bargain for goods along the street-stalls near the coast and those that we took photos with were not most or all wiped away by the tsunami. I guess I'm really lucky to be alive for if I have stayed there a few more days, I wouldn't be writing my reflections now.

MEGASTRUCTURES: Singapore's Vegas

Nat Geo's MegaStructures season 6 did a report on one of the two Singapore's Integrated Resort, the Marina Bay Sands, owned by Las Vegas Sands Corp whom invested $5.5 billion USD into building the MBS. The challenges architects, designers and engineers faced when constructing the megastructure. Though most of the these architects, designers and engineers are world renown for their artistic masterpieces of infrastructure, but never before have they tried building such a massive structure of three 55 storey high hotel towers joined together by a 1 hectare sky park on not normal land, but with only 560 square metres of reclaimed land. Especially with the slanted design of the tall building and situated at the bay front where wind power is the strongest, there is a high possibility of the tower buckling on its own weight and collaspe. This weight alone on the reclaim land is worrisome enough, what's even more distressing is that the architects are adding "artwork" into the already seemed like a state-of-the-arts masterpiece by hanging 50 (or was it 15?) tonnes worth of steel in sophiscated shapes on air in the lobby of MBS. Have the engineers not thought of the possibility of the reclaimed land that might sink in future?

With the lessons learnt from the 2004 incident; collaspe of the Nicoll Highway due to soft marine clay, the engineers combat it by building giant concrete walls AKA diaphragm walls to allow easier constrcution of MBS without water coming in. I think even without the problem of marine clay, it is still very dangerous to build such huge project on a recently claimed land. Moreover, these diaphragm walls weren't created as a solid foundation to build MBS, but only to prevent sea water from entering. Moshe Safdie, one of the chief architect mentioned that this whole project was supposedly a 6 to 7 years project, but shortened to 3 years to complete. The number of years for completion is literally shortened by half and I can't help but link to the thinking that there might by some exploitation of workers involved and shabby work done with inferior materials. Though it may sound unlikely a place as strict as Singapore, but one may never know as it does indeed sound impossible for me to imagine completing such a huge project with only 3 years without constant overtime working of onsite workers. In addition, during the period of constructing MBS, there was a global crisis in September which made me feel even deeper of the possibility.

Forutnately, as of now there are no typhoons or heavy rainstorms sighted in Singapore or it would be very consequential to MBS. As mentioned, MBS is not only built on reclaimed land but it is also facing directly towards the bay front where wind power is the strongest. Strong wind can cause buildings to sway and may ineveitably damage the sky park if not constructed properly to withstand these wind. Engineers have came up with flexible construction of the sky park so that it wouldn't collaspe when wind blows. However, this is only if the wind power is within the calculations of what the engineers think the building can withstand. And these calculations are normally based on the average wind intensities faced in Singapore. If let's say Singapore that has never before been hit by a typhoon is hit by a strong one, then in my perspective I think that the building may, or definitely will collaspe. The sky park can only deform up to 200 millimetres (20cm).

If you think building the 3 hotel towers and sky park sounds dangerous and impractical alreasy, wait till you hear the ArtScience Musuem. It seemed even more unsound to have it built in water! But well, even if it's impossible, engineers and architects would have to find solutions to make the impossible possible. They built 3 pavilions in 6 metres under water in order to construct the ArtScience Musuem. Water is then pumped out of the pavilions into the sea. However, there is a danger of hydrostatic pressure where the increase in sea level would cause the water pressure outside the walls to increase thus damaging the pavilion. And surely, the pavilion walls started to show signs of leakages where the architects hired 8 professional divers to search for the leakage spots and plaster them up. Though I don't know anyway of solving this problem either, but I think that hiring divers to plaster up the leakages isn't exactly a good solution too. The water is too dirty for the divers to even see where they are swimming underwater, hence they only rely on the feel of the suction of water towards the walls and this "feel-only-and-plaster-up" solution doesn't sound safe to any of us. The divers may miss one or two spots that might be too subtle to feel it and in the future, with the completed ArtScience Musuem weighing on it, the cracks may widen and eventually the pavilion may be damaged, sinking the whole musuem.

I think that the MBS is indeed one of the wonders in Singapore's infrastructure, but these factors of where and how it was built make me dare not think of how it would become in the next decades to come.
