Coal is considered a non-renewable resource because it is a fossil fuel that takes millions of years to form. It is created from the remains of plants and trees that have been compressed and heated over time. Once coal is extracted and burned for energy, it cannot be replaced within a human timescale. Therefore, it is classified as a finite resource that will eventually be depleted. Additionally, the process of coal formation and extraction also has significant environmental impacts, further reinforcing the importance of transitioning to renewable energy sources.
