In which situation can negative feedback stabilize an environmental system?
Answer and explanation
Correct answer: Rising pollution leads to stricter controls and lower emissions
Negative feedback counters or reduces the initial change. If pollution rises, stricter regulation, cleaner technology or reduced demand may lower emissions and push pollution back toward a safer level. By contrast, more pumping after greater water use and faster extraction after rising demand reinforce the original pressure, representing positive feedback. Therefore B is the stabilising example.
