What is a type of resources that cannot be remade and can run out?

A type of resource that cannot be remade and can run out is a non-renewable resource, such as fossil fuels (like coal, oil, and natural gas) or minerals. These resources are formed over millions of years and are consumed at a rate that exceeds their natural replenishment. Once depleted, they cannot be replaced within a human timeframe, leading to potential shortages and environmental impacts.
