A non-renewable resource is a natural resource that cannot be replenished or replaced at the same rate it is consumed. These resources have a limited supply and take millions of years to form, making them finite and non-replenishable within a human lifespan. Examples of non-renewable resources include fossil fuels (coal, oil, and natural gas), minerals (such as gold, silver, and uranium), and nuclear energy sources. Once these resources are depleted, they are no longer available for use.
