Answer

The main human activities responsible for increase of the carbon dioxide gas in the earth’s atmosphere are —

  1. The burning of fuels, deforestation, transportation and industrial production (particularly cement factories).
  2. Increase of population (human beings emit nearly 32 gigatonnes of carbon dioxide each year).
  3. Imbalance of carbon dioxide cycle (the ocean does not absorb full amount of carbon dioxide and plants are not able to change all the carbon dioxide into oxygen).

The increase in concentration of carbon dioxide due to the above human activities is responsible for 60% increase in green house effect.
