Task 3:  Creative  thinking  and  writing  activity.

  Part 1- Effects of water pollution on an ecosystem.

  (1) Read the brief information below on the effects of water pollution on an ecosystem.

The effects of water pollution are varied and depend on what chemicals are dumped and in what locations. In Papua New Guinea, many bodies of water near mining areas are highly polluted.  This is the result of dumping waste which contains toxic chemicals. The main problem caused by water pollution is that it kills life that inhabits water-based ecosystems.  Dead fish, birds, dolphins, and many other animals often wind up on beaches, killed by pollutants in their habitat. Pollution disrupts the natural food chain as well.  Pollutants such as lead and cadmium are eaten by tiny animals.  Later, these animals are eaten by fish and shellfish, and the food chain continues to be disrupted at all higher levels. Eventually, humans are affected by this process as well. People can get diseases such as hepatitis by eating seafood that has been poisoned. Ecosystems can be severely changed or destroyed by water pollution.  Many areas are now being affected by careless human pollution, and this pollution is coming back to hurt humans.


 (2) Study the effects of water pollution on a marine food chain in the sea ecosystem. Use the links below to get more information on the          effects of water pollution on a water-based ecosystem.
 (3) Type your answers to the questions on a word document.
 (4) Save your word document file in your folder.

   
              Part 2-Creative thinking and writing using six thinking hats activity.

     (1) Imagine that you are one of the natives of a prospective mine site in Papua New Guinea. The exploration company has finished its feasibility studies on the potential of your land which has a huge deposit of minerals. However, the production site is near a big river. This river has supplied a lot of resources for the people in the village, including food such as fish, water for drinking and washing. On the other hand, this river has been a habitat for the marine creatures, including crabs, fish, and turtles. Also, this river is a tributary that connects to the sea. Consequently, as the production in the mine takes place, it will have an enormous impact on the river.

     (2) Using the above information, you will do an activity using the six thinking hats. Below is a summary of the six thinking hat questions.

  °White hat question - asks for information and facts.  For example, what is pollution?
  °
Blue hat question- asks for organising thoughts. For example, what have we done so far?
  °
Yellow hat question- asks for good points. For example, why is it important to study pollution?
  °
Green hat question - asks for creative ideas. For example, what are some other ways to solve the problem?
  ° Black hat question- asks for bad points. For example, what is one long term effect of water pollution?
  °
Red hat question- asks for emotions.  For example, how do I feel about this right now?     

     (3) Think of  the benefits  of  the  mine, including  spin  off businesses, royalties  paid  to landowners  and  other  social
            benefits. On the contrary, think of the short, medium and long term effects of the mine on the river.

     (4) Type your six thinking hat questions and answers by following the instruction on the word document.

 (5) Save your word document file in your water pollution folder.
