Which of the following is NOT considered renewable natural capital?

Fossil fuels are classified as non-renewable natural capital because they are formed from decomposed organic materials over millions of years. This process takes much longer than the rate at which humans extract and consume these resources, making fossil fuels finite and unsustainable in the long term. In contrast, renewable natural capital refers to resources that can be replenished naturally at a rate that allows for their sustainable use.

Timber, food crops, and freshwater resources all fall under this category, as they can regenerate or are replenished through natural processes, provided they are managed responsibly. For example, forests can regrow if harvested sustainably, crops can be cultivated annually, and freshwater can be replenished through the water cycle. Thus, fossil fuels stand out as the only option that is not renewable.
