Input:  Person1:     I think the biggest environment problem in my country is air pollution .  
 Person2:  Yes , I agree . The air here is much more polluted than in my country . Of course , my country is more agricultural and has much less industry .  
 Person1:      We have reduced emission of air pollutants in recent years , but cars are still a major source of them . Factories have become cleaner as stricter environment pollution law have been introduced .  
 Person2:  The problem is now on a truly global scale . I don't believe that any single country can do anything about it .  
 Person1:      I think you're right . There needs to be an international response to this problem ?
