What is the definition of natural resources?

1. A source or supply that occurs in nature without human action

2. Any material that has been altered by human intervention

3. A man-made source of raw materials

4. Resources found only in urban areas

The correct answer is: A source or supply that occurs in nature without human action

The definition of natural resources refers to materials or substances that exist naturally in the environment and are supplied by nature without human intervention. This includes elements such as air, water, minerals, plants, and animals that are utilized for various purposes including economic, ecological, and recreational uses. Natural resources are integral to life and the functioning of ecosystems, serving as the foundational elements for energy production, agriculture, and manufacturing, among other activities. The correct choice highlights the inherent aspect of these resources being free from human alteration or creation. This distinction is crucial as it contrasts with other types of resources that either require human enhancement or are entirely fabricated or manipulated by human activities. Understanding this definition is essential for any environmental manager, as it lays the groundwork for managing, conserving, and utilizing these resources sustainably. In contrast, the other options define resources in relation to human influence or specific geographic locations, which do not align with the concept of natural resources. Specifically, defining resources that are altered by human intervention or identifying them solely based in urban areas does not encapsulate the essence of what natural resources are.
