Correct Answer: Emission of Carbon Dioxide
Burning fossil fuels such as coal, petroleum, and natural gas primarily releases carbon dioxide (CO₂) into the atmosphere. Carbon dioxide is a major greenhouse gas that traps heat and contributes significantly to global warming and climate change. Fossil fuel combustion also produces pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which can cause acid rain, smog, and respiratory diseases. Since the Industrial Revolution, increasing fossil fuel use has greatly increased atmospheric CO₂ concentrations. Many countries are therefore investing in renewable energy sources, energy efficiency, and cleaner technologies to reduce greenhouse gas emissions and limit the impacts of climate change on the environment and human health.
