Which of the following is correctly classified as a non-renewable resource?

  1. Fishes in oceanic stocks within sustainable yield
  2. Fossil fuels such as coal and petroleum
  3. Freshwater from perennial Himalayan streams
  4. Trees in a managed plantation forest
Show answer and solution

Correct answer: B. Fossil fuels such as coal and petroleum

Non-renewable resources are those that get exhausted with extraction and use. Fossil fuels — coal, oil, natural gas — regenerate over geological time scales, so on a human time horizon they are non-renewable. Trees, fish and freshwater can regenerate if harvested within their carrying capacity.
