Systems Thinking Research Post

In 1950 ,the Dayak people of Borneo an island in Southeast Asia were suffering from an outbreak of malaria. So they asked for WHO or World Health Organization for help .WHO's solution is to spray copious amount of DDT (Dichlorodiphenyltrichloroethane) around the island .The result is that the mosquitoes were killed so did the malaria.

But the side-effect is that DDT also killed some kind of wasps that control the population of thatch-eating insect ,and the roofs of Dayak's people homes got eaten by these thatch-eater. The DDT alloyed in many insects on the island including gecko which is the food of cats ,cause the cats who dine on gecko to die and population of rats came up alot. The rats caused even more problems to Dayak people by eating their grains and spread the plaques. The Dayak people asked for WHO for help again and now the solution is to send cats parachute into Borneo and finally now the cats stabilize the situation.

 System Thinking means to think of a whole ,look at the picture from many views or looking at whole. In my opinion system thinking is important because humans we're social animals that rely on each other  and to decide or do something  we have to think as a whole .Doing business needs system thinking as a main construction to make a decision .To play stock market you need to look at many different things and make sure that you're investing on the right side and will get profit back.

Plastics Creative Component


Research Question Confirmation

How does non plastic bottle and plastic bottle affect affect people height?
I'll ask the participants which can be both genders men and women. For example 1:What kind of bottle do you use at school ,plastic or something else? 
2:How long have you been using it?
3:How tall are you ?

RN: Energy Resources

Range of Energy resources 

Both Renewable and Non-renewable resources can generate energy. But we can clearly see that renewable resources are more sustainable because there's no depletion of natural capital such as solar power hydroelectric, geothermal, biomass and tidal schemes. Which is opposite for non-renewable resources that cannot be replenish such as fossil fuels . 

  But according to worldwide energy consumption chart in 2004 we can see that most of the people use non-renewable resources much more than renewable resources because it's cheaper and doesn't require much process .


Advantages and disadvantages of energy sources

Fossil Fuels are the energy resources that is formed when dead animals or plants decompose ,the process takes more than thousand years.

  • Gas and oil are made from oceanic organisms . 
  • Coal is from land plants (mainly from trees growing during the Carboniferous Period).
  • Fossil are made from the dead preserved dead organisms
These energy sources contain alot of carbon from under the water which when the energy are used up it will release quite amount of carbon.

Fossil Fuels

  • Cheap and plentiful but it contribute climate change and unsustainable.
  • There are technologies controlling pollution from the fuels but it's getting more difficult to extract the fuels 
  • Oil can be delivered over long distant by pipeline but oil spilling is very dangerous for nature ecosystem and living organisms
Nuclear Power
  • Nuclear power plant produces radioactive waste that can last for thousands of years but does not produce carbon dioxide or the cause of climate change  
  •  A large amount of energy can be generated in a single power plant but it is extremely dangerous if something unexpected happens to the power plant such as terrorist attack .

Advantages and disadvantages of renewables

  • Fossil fuels are cheaper 
  • The locations of renewable resources are limited 
  • Cannot run out because the resources are renewable 
  • Produce fewer emissions 

Hydroelectric power


The turbines can be switched on whenever it’s needed — it’s reliable.

The disadvantages of HEP is that many areas may be flooded (habitats, farmland and displacement of people).

Tidal power


It produces energy by using the ebbing or flooding tide to turn turbines.

Disadvantages of tidal power

It required to generate sufficient energy and the right shape of coastline to channel water through the turbines.

Solar energy


It’s very expensive to turn into high quality energy for manufacturing (compared to using fossil fuels).

Passive solar energy (combine with insulation) is cheaper for heating homes than fossil fuels.

The disadvantage is that it’s limited in northern countries during winter months.

Wind power


Produced by wind turbines.

The disadvantage is that if there’s no wind, no energy is generated.

The location of the turbines is hard, it need to be in areas of consistent high wind.

Biofuel 


Biofuel energy is produced by burning plant material to produce heat.

Disadvantages of biofuel is that it produces emissions and require large amounts of land to grow the biofuel crop.

Wastes


It can be burned to generate energy.

Advantages of wastes

It’s available at all times and it does not deplete natural capital.

Disadvantages of wastes

The burning adds to global warming gases.

Geothermal energy


Can be obtained from heat in the ground.

It does not release any form of pollution.

Research Project Ideas

1:Our first idea is Kayak from plastic bottles which around 2 average people can sit on
2:The next idea is a lamp made out of recycled plastic bottles
3:And a chair made out of plastic bottles which is easy to make but useful

Nepal Earthquake

What is the causation of this incident?

Earthquake is movements within the Earth’s crust cause stress to build up at points of weakness, and rocks to deform. The reason of this devastating event is the regular movement of the fault line that runs along Nepal’s southern border, where the Indian subcontinent collided with the Eurasia plate 40 million to 50 million years ago.

When did it happen?


An earthquake with magnitude 6.7 occurred near KATHMANDU, Nepal at 07:09:08.90 UTC on Apr 26, 2015.

Lost

Estimated around 3218 people who have confirmed lost their lives by morning Monday April 27 2015 (the number has risen up to around 3800) and more than 6000 injured  ,most the building, temples and landmarks are destroyed  

Effects

The US is sending a disaster response team and $1m also are India China Japan UK Pakistan UNICEF and many other countries including Thailand are sending help aids medical teams to Nepal .

Idea

We can help donating the money to the people who contact to Nepal organization ,helping them out though its not that much.
