What is the meaning of nonrewable resources?

Nonrenewable resources are Natural Resources that cannot be replenished or regenerated within a human timescale once they are depleted. Examples include fossil fuels like coal, oil, and natural gas, as well as minerals and metals. The consumption of these resources leads to their eventual exhaustion, making their sustainable use a critical concern for future generations. Once depleted, nonrenewable resources cannot be replaced or restored, which poses environmental and economic challenges.
