A decision you can investigate
- A delivery depot creates engine noise, exhaust fumes, litter and contaminated runoff.
- A single pollution label can hide different harms and different remedies.
Build the explanation
- Visual pollution 视觉污染 includes litter or damage to a landscape; noise can disturb neighbours; air pollution harms air quality; water pollution contaminates waterways. Business activity can cause several at once.
- A tax changes the cost of a harmful activity; a subsidy helps finance cleaner action. Legislation 立法 authorizes rules; regulation specifies requirements. Fines penalize breaches; pollution permits limit allowed emissions. Public parks can preserve green space and provide recreation, but do not automatically clean polluted water.
Work through the evidence
- The depot can install a runoff filter costing 5000 yuan. A 2000-yuan subsidy leaves 3000 to fund. A rule requiring safe discharge directly targets the water harm; inspections and credible fines support it.
- A park may improve access to green space, while a night-delivery restriction targets noise. Match the chosen tool to its mechanism instead of treating each policy as interchangeable.
A filter costs 5000 with subsidy 2000. The firm funds
The subsidy covers part of the cost: 5000−2000.
Test the limits
- Regulation may achieve a clear minimum but impose costs and need monitoring. A fine’s effect depends on detection as well as size. Permit trading requires measurable emissions and an enforced cap.
- Parks need land and maintenance spending, with an opportunity cost. Compare environmental gains with implementation costs and effects on output, workers and residents.
Which intervention most directly targets late-night engine noise?
The rule targets the source and timing of the noise.
Government provision of a park has no opportunity cost.
Land and maintenance resources could have other uses.
Apply and explain your answer
- Why is a new park alone an incomplete response to contaminated runoff?
- It does not directly prevent or treat the discharge reaching the water.
What can weaken the deterrent effect of a large fine?
An unenforced penalty may leave expected costs low.
Use the terms precisely
- visual pollution: Damage to the appearance of an environment, including litter.
- legislation: Laws establishing authority, duties or prohibitions.
Match the terms to their meanings.
