#1-My personal understanding about trashes and pollution before watching “bag it”

Question: Before you watch the movie, try to answer these questions:
What is trash? Where does it go? How does it affect our environment? Discuss how landfills, and the toxicity they create — methane, leachate, greenhouse gases — impact our environment. Why is leachate in our aquifers a bad thing?

Answer: As far as I am concerned, trash is something that we thought that we would never use again, at least at the moment we threw them out. They are usually something ordinary, which means they are commonly used in our daily life and are very likely to be consumables. It is their easiness to be substituted and replicated that makes them trash. However, we seldom care about where do they go after being thrown away. From the knowledge that I have now, I imagine there is a plant specialized in recycling or only degrading the trashes, and that is where they may go. However, since we are producing tons of trashes every day, it must be hard or even impossible to process them all at the same speed we produce them. Therefore, the trashes that is not able to go to the processing planet may be stored outside in some rural areas, and the soil and water around them will be severely affected.

Based on the knowledge that I acquired in one EAP course that I previously took, which talks about sustainability, I got to know that toxicity like methane and greenhouse gases are causing obvious climate changes. For instance, the most known-to-all one, global warming, and other long-term consequences like sea-level rising, land desertification, and so on. And for leachate, it causes severe problems like groundwater pollution. Due to the fact that groundwater pollution is processing slowly and hard to discover,  seldom do we pay enough attention to it. However, its impact is much more harmful than we thought. Groundwater is an important part of the precious freshwater resources in the world, and it needs many years to gain from the rain and make it pure. There is a large part of the water we used daily coming from groundwater. As you can see, groundwater pollution will affect our lives a lot.
