Air Pollution - A Global Dilemma?

📌 CONCEPT: Biofuel is a cleaner alternative to fossil fuels that can reduce air pollution by providing a sustainable and renewable energy source.

📐 RULE / FORMULA: The main principle behind using biofuel is the reduction of greenhouse gas emissions (GHGs) and other harmful pollutants that contribute to air pollution.

💡 WORKED EXAMPLE: Suppose a city switches from using fossil fuels to biofuels for 50% of its transportation needs. If the biofuel reduces GHG emissions by 70% and other pollutants by 80%, the city can expect a significant decrease in air pollution levels, thus improving the health and well-being of its citizens.

⚠️ COMMON MISTAKE: Many students often overlook the potential drawbacks of biofuel, such as land use changes, water pollution, and competition with food crops, which can lead to unintended consequences and even exacerbate air pollution in some cases.
