ALINA: Recently I read an article about global warming. I am worried to know that global warming is going to become the most dangerous threat to the existence of humans.
GABBY: I often watch news about it on TV. World leaders talk about its serious consequences.
ALINA: Automobiles, air-conditioners, refrigerators, industries, electricity generation plants etc. are contributing to global warming. And their number is increasing day by day.
GABBY: Deforestation of the earth is also a big reason.
ALINA: There is an increase in the greenhouse gases: carbon dioxide, methane, nitrogen oxide etc.
GABBY: Due to these gases the whether of this earth will continue getting warmer.
ALINA: On one hand we are progressing on the other it is proving our down fall.
GABBY: Do you think all the countries will get united to face the threat to human life?
ALINA: At present it is really difficult. Because every country is thinking about its economy. If this world seriously takes some steps it may dent the economy of all the countries.
GABBY: One thing is clear; it won’t be easy to control global warming.
ALINA: But when the temperature on this earth rises the snow will melt, the water of the seas will rise. The living place on this earth will start shrinking.
GABBY: And there will be many more problems. Our scientists must find some solution.
