Give an example of a non-renewable resource.

Coal is a prime example of a non-renewable resource because it is formed from ancient plants and organic matter that underwent a long process of heat and pressure over millions of years. Once extracted and consumed, it cannot be replenished within a human timescale, making its availability finite. In contrast, renewable resources like wind energy, water, and solar energy can be replenished naturally and are sustainable over the long term. This characteristic of coal highlights the importance of managing non-renewable resources responsibly, as their depletion can lead to environmental concerns and energy insecurity.
