Nonrenewable resources cannot be replaced. This statement is not true because nonrenewable resources, by definition, are finite and cannot be replenished once they are depleted. Examples of nonrenewable resources include fossil fuels like coal, oil, and natural gas, as well as minerals like copper and gold. These resources take millions of years to form and cannot be regenerated within a human timescale. Therefore, it is important to find alternative and sustainable sources of energy to reduce our dependence on nonrenewable resources.
