→ Renewable and Non-renewable Resources: Natural resources may also be classified as renewable-that exist in unlimited quantity like sunlight or non-renewable that are in limited quantity like petroleum.
→ On the basis of distribution, a resource may be ubiquitous like air-found everywhere or localized-found in certain parts only like minerals.
→ Humans have used their intelligence to create certain resources like; vehicles, buildings, roads, etc.
→ Humans themselves are a resource like farmers, labourers, teachers, doctors, etc. Human resource development is essential for further development.
→ We need to conserve resources for fulfilling present and future needs. This is known as sustainable development.
→ Early man was fully dependent upon the environment.
→ Human needs depend upon the natural environment and level of social, cultural, and technological development.
→ All biotic resources can reproduce and regenerate and thus are renewable.
→ The utility of resources largely depends on their location.
→ Anything that can be used to satisfy a need is called resource.
→ Time and technology are two important factors that can change substances into resources.
