A growing global population that consumes natural resources is partially to blame for the release of greenhouse gases since human consumption patterns lead to deforestation, soil erosion, and farming (overturned dirt releases CO2). However, the critical issue is the burning of fossil fuels (hydrocarbons) such as coal oil and natural gas to produce energy that is used for things like electricity production, and vehicle, heating, and cooking fuels.
