the burning of larger amounts of wood and fossil fuels
An extracted and burned fossil fuel[a] is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remains of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels. Fossil fuels can be used to produce energy, power engines (like internal combustion engines in cars), or supply heat for immediate use (such for cooking or heating). Before burning, some fossil fuels are processed to produce derivatives like kerosene, gasoline, and propane. The anaerobic decomposition of buried deceased animals that contained organic molecules produced by photosynthesis is the source of fossil fuels. [4] The geological process that transforms these elements into high-carbon fossil fuels often takes millions of years.
