1. Climate change
   climate refer to the average weather condition of an area. It is a truism that any      changes in climatic condition may affect agricultural production, pattern of              rainfall, wind flow and migration of animal.

2. Global warming   
     Continuous increase in the emission of Co, from different sources into the              atmosphere affects the heat balance of the earth. Continuous increase in the        concentration of green house gases in the atmosphere trap more heat and            prevents the heat from the earth’s surface 

3. Greem house effect
    Green house effect is another environmental crisis facing our world.                       Chlorofluoro carbons (Co2) carbon dioxide, Methane (CH4) and Nitrous oxide       (N,0) are called as green house gases.
