3. COAL AND PETROLEUM

Coal, petroleum, and natural gas are critical fossil fuels formed from the remains of ancient organisms millions of years ago. Their extraction and use as energy sources raise concerns about their exhaustibility and environmental impact. Sustainable practices and reductions in fossil fuel dependence are necessary to mitigate global warming and ensure their availability for future generations.
