                                              Summary

     In“the causes of global warming ”，Jonathan Hayle(2010)
writes that there are many causes of global warming such as
Natural phenomena, human activities, human consumption and human production.

   Firstly, many natural incident can decrease temperature on
Earth, like more rays could make the temperature higher.Also Methane gas transmitted into atmosphere, therefore it makes the global warming.

    Secondly, the narrator talks about the human activities and

human consumption. For exemple, farm animals and fertilizers, integral in agriculture produce methne,which is great greenhouse gases for the global warming. Also the production of electricity make an effect to global warming.

   Third, the reasons of global warming is human consumption. The use of energy and the use of cars produce baneful gases. And the manufacturing of products makes a big amount of energy. For example,the electronic and the products or goods include bad materials which could destroy our environment. Therefore it makes global warming.

     In conclusion, global warming have the relationships with

naturals phenomena and human activities which have the

negative effects and crisis on the global warming.
