In this reading, a perfect example of a closed system versus an open system is shown. It is really cool how we see exactly how nature works through something like this. Inside the truck, things age and become dust-covered, but nothing grows. In contrast, outside in the bed, where there is a combination of sun, wind, and rain, plants such as poison ivy and albizia have begun to grow. Leaves decomposed through natural process and is now the soil to these plants.
After I read this I was reminded how special the processes of our Earth were. The process of growth and reproduction of plants is remarkable. You can begin to understand the power of Nature and how special it is. You can begin to see how nature works in each stage as well: leaves that are blown into the truck from the wind along with seeds from nearby trees, rain and pigeon excretion begin to start the growth of the seeds into the decomposed leaves, and the sunlight gives the seeds energy needed to begin growing. Seeing all of this take place in the bed of the truck is pretty awesome.
