Causes of global warming

 Natural pollutants like volcanoes, fires and dust storms.  The processing of oxides, toxic materials and organic materials.  The burning of natural fuels like charcoal.  The use of transporters where fuel is being used.  The over-exploitation of natural resources.

The impact of global warming:

 Air pollution increases.  Certain areas get drier and the plants die.  The oceans’ water levels rise and it leads to the flooding of lower lying areas.  Water resources get exhausted.  Rainfall patterns become unpredictable.  Health risks increase due to the temperature rising.
