In this section, we learn about resources which are defined as any item that can be used to satisfy a need. The importance of utility and value is emphasized, with examples provided to illustrate various resources in our daily lives, such as water, electricity, and textbooks. Resources are classified into three main types: natural resources, which are derived from nature; human-made resources, which are created from natural substances; and human resources, which refer to the skills and knowledge of individuals. Additionally, the discussion includes the significance of renewable and non-renewable resources, the impact of human activities on resource availability, and the crucial need for sustainable development to conserve resources for future generations.
