- Consumption of fossil fuels and house-hold fuels like coal, firewood also gives off considerable amount of carbon-dioxide.
- There is a natural carbon cycle in the atmosphere managing CO2 level however various human activities are altering this by adding more CO2 gas to the atmosphere by reducing natural sinks like forests.
