Solution:  Most of the human activities such as burning fossil fuel, use of refrigerators and air conditioners  lead to emission of greenhouse gases in the atmosphere. Industrialization is causing more and more carbon dioxide emission. 

Main activities promoting the release of carbon dioxide in air:

  • Combustion of fossil fuels such as petrol, diesel, coal for transportation, electricity generation and industrial use. 

  • Household use of coal and kerosene for cooking and heating. 

  • Deforestation for urbanisation.
