Final answer:
The arrangement of activities based on their contribution to climate change, based on the limited information provided, begins with transportation systems leading at 28.2 percent, followed by energy production at 26.9 percent of US greenhouse gas emissions. Precise figures for other sectors are not provided, thereby preventing a complete ordered list.
Step-by-step explanation:
The student's question is about the arrangement of activities in decreasing order of their contribution to climate change based on the data of US sources of greenhouse gas emissions by economic sector in 2013. Unfortunately, the question does not provide the exact figures or percentages for each sector, which would be necessary to arrange them in the requested order. However, based on the information given in the supporting text, we can deduce that the two largest contributors to greenhouse gas emissions in the US are energy production, particularly the use of fossil fuels for electricity, and transportation systems, which include the consumption of fossil fuels for transportation.
For example, the text mentions that energy production accounts for 26.9 percent of U.S. emissions. Consequently, one can infer the economic sectors contributing to greenhouse gas emissions would be ranked as follows, starting with the two largest known contributors:
- Transportation systems (28.2 percent of emissions)
- Energy production (26.9 percent of emissions)
Other sectors possibly contributing to greenhouse gas emissions would follow but were not explicitly stated in the question. Moreover, recommendations from the US Environmental Protection Agency suggest adopting alternative energy sources, energy conservation, and reduction in the use of fossil fuels to mitigate the climate impact of these emissions.
