Humankind has relied heavily on fossil fuels which has led to environmental issues. Fossil fuels are formed from remains of dead plants and animals and are used for energy in many applications. However, their use contributes to climate change through carbon dioxide emissions and has other disadvantages like pollution, health impacts, and finite supply. While fossil fuels have benefits like wide availability and high energy output, their overconsumption is not sustainable and is causing problems that must be addressed.
