                        EFFECT
    
 There are a lot of problems at the beginning of the new century. People suffer air, water and land pollution. 
People have produced a lot of carbon dioxide (CO2).   It doesn't allow the heat to escape back. The atmosphere becomes warmer. It is called the "greenhouse effect".

Why is it happening?

  Pollution sends 4 main 'greenhouse gases' into the atmosphere. These are:
1) Carbon dioxide (CO2)                            2) Methane
3) CFCs (Chloro-fluoro-carbons)              4)Nitrous Oxide
