We learned about plastic. We spended a lot of time to discuss about what happens to plastic waste. We found that in Cambodia people liked to burn, bury, throw away and put in the landfill. When we burned rubbish it had co2. Which mean carbon dioxide that the plants took and it let out oxygens out for us, but if it had a lot of co2 it increase the chance that global warming, greenhouse effect and drought could happened. When the world have global warming the ice will melt and some animals will lose their habitats because some animals need cold place to live. Example polar bears needed cold place to live, but if we burned rubbish the cold place like Arctic will melt and then polarbears went extinct. Also, when global warming happened the world got hotter and the oceans got hotter too. If the oceans got hotter the animals that in lived in the oceans will die like jelly fish because they like to live in normal climate.  When the drought happened and then the organisms will die because all organisms need water to stay a life.  Also, when the drought happened the desserts got bigger and it had a lot of winds and sand storms. When we buried it could polluted to the water and soil. So we can’t grew the plants on that soil again. When we threw the rubbish away it could clogged the drain and it could had flood. Why rubbish could clogged the drain because when the rain came the water can’t went through the drain because of  rubbish were clogging already. So when rain came a lot and it can’t went through the drain it could have flooding. when we put the rubbish at the landfill  the problems were taking a lot of space, have leaching chemical and methane gas. Leaching chemical when the chemical came out slowly. Example when the rain came it stayed in the plastic that in the landfill and slowly the chemical came out. This chemical was not good for our health. Methane gas were 21 times  more dangerous than co2.We were researching about solutions that could helped to reduce waste. Our solutions were 3R and 5D. 3R means reduced, reused and recycled. Reduced means used less plastic. Reused means used it again. Example if you have one plastic already don’t threw it away tried to used it again when you went to shopping. Recycle means when you used the plastic already you could put it into factory to made more plastic bags. When you have plastic and you wanted to threw away you have to think could I reduced this plastic. Then you have to think could I reused it and then if you can’t reuse you could recycled it. 5D means define, discovered, design, develop and deploy.

In our class we have other solution. That solution was reusing plastic. We made many things out of plastic for people to use it. Many students had made the bags out of plastic for carried some things when you went to shopping. One student had made flower from the plastic. That flower you could hanged it in front of your house or on the table. Our project were so helpful because all the bags and flowers were the things that people wanted and needed.

When we used plastic it have benefit too. People used plastic as materials. Plastic we could used it in many different climate.  Plastic could packaged food and water and then that food & water will safe. It can keeped the food be fresh. The best reason why people liked to used plastic because plastic doesn’t cost a lot of money.

We had 4 trips that we went to Phnom Penh. The first trip we went to Lucky market to interview the seller about plastic. The second trip we went to BKK market to interview the seller and the buyer about plastic. We went there to observe how people used their plastic.  We had went to Cintri. Cintri was the company that took the rubbish to put at the landfill. The last trip we went to community to ask about plastic and then we took that information to studied.
