Limited resources refer to the finite amount of natural or human-made resources available for use. These resources can be energy sources, materials, minerals, or any other type of resource that is essential for human consumption and well-being. The term "limited" indicates that there is a finite amount of these resources, and they cannot be renewed or replenished naturally within the time frame necessary for human consumption. Therefore, it is crucial to manage these resources carefully and efficiently to ensure their sustainable use and to avoid depletion.
