g what we have sown, and we have to pay the price for the consequence. It is no exaggeration to say that our existence would be impossible unless we resort to environmentally friendly remedies. The scene in the picture is shocking: the severe drought has turned the farmland into cracked pieces of baren soil. A helpless farmer is gazing at the cloudless sky in despair with dried?up shoots in his hands. Obviously, what he wishes for is nothing but a long due rainfall, for continuous drought must result in crop failure followed by famine.Traditionally, drought has been regarded as one of natural disasters. But nowadays it involves environmental impact of man?made pollutions, especially the emission of CO2 into the atmosphere, which causes hazardous changes in the earth climate, such as global warming, droughts, floods and so on. There are the nature?s punishment and revenge on humans for their selfish conduct.To survive the crisis requires global efforts in many ways: decreasing energy consumption, reducing and finally banning discharge of harmful exhaust fumes and substances into the air, saving fresh water resources, improving irrigation systems, etc. In brief, we are eating what we have sown, and we have to pay the price for the consequence. It is no exaggeration to say that our existence would be impossible unless we resort to environmentally friendly remedies.
