Non-renewable natural capital Natural resources that cannot be replenished within a timescale of the same order as that at which they are taken from the environment and used; For example, fossil fuels. cebitz. n coScie m
  • 7. 3.2: Resources - natural capital 3.2.3: Explain the dynamic nature of the concept of a resource. The resources we use change over time For centuries wood was the main source of energy for most of Europe as well as the rest of the World. During the last century oil has become the most important energy resource cebitz. n coScie m
