A major characteristic of natural resources is they

A major characteristic of natural resources is that they are free gifts of nature. This means that they are not produced by humans, but are found naturally in the environment. Examples of natural resources include water, air, forests, minerals, and fossil fuels. However, although natural resources are free in the sense that they are not created by humans, their extraction, production, and transportation often involve costs. Additionally, some natural resources may become scarce over time due to overuse or depletion, leading to increased prices and a greater focus on sustainability and conservation efforts.
