Q1
A company is deciding how quickly to increase production of aluminum cans. The model below summarizes a key step: more can production requires more electricity, and the electricity is generated mostly by burning coal.
Evidence: In a pilot plant, when production increased from 1 million cans/day to 2 million cans/day, electricity use increased from 50 MWh/day to 95 MWh/day, and estimated SO$_2$ emissions increased from 100 kg/day to 190 kg/day.
Which explanation best links the consumption change to an Earth system impact, including that impacts depend on the amount and rate of use?
