Natural resources are defined as substances drawn from nature that can satisfy human needs. Their importance comes from their utility, which gives them value. The section elaborates on how resources can be classified as renewable (such as solar energy or wind) and non-renewable (like coal and petroleum) based on their ability to regenerate. Additionally, it discusses the impact of human activities on these resources and emphasizes the role of technology and human innovation in creating new resources. Therefore, understanding natural resources is crucial for sustainability and future use.
