From Digit, we learned about the hydrologic (i.e., water) cycle, the carbon cycle, the nitrogen cycle, and the phosphorous cycle. In doing so, we learned how humans can impact each of these cycles. Describe one way that humans impact two of these cycles (independently), and what the consequences to that environment are. Each (separate) description is worth 4.0 pts, for 8.0 pts total. For your answer, make sure to state which cycle you are referring to (e.g., oil cycle), how humans directly affect the cycle (e.g., burn tires), a description of the affected cycle (e.g., burning tires takes oxygen out of the water, which causes less rain), and a description of the side effects (e.g., consequently ocean pH rises). Answers must come from Digit.
