Greed or Greet?
　　The earth has nurtured generations of human beings, offering us with every resource to survive and prosper. Nowadays, with the explosion of population and boom of economy, human’s relentless exploitation of natural resources has caused crisis of exhaustion of energy and resources. The remark “Earth provides enough to satisfy every man’s needs, but not every man’s greed.” gives out a warning for us all.
　　The ecosystem has remained balanced until man becomes obsessed with their ambition to conquer Nature and they are blinded by greed. On one hand, they are so economy-oriented that they ignore the protection of environment. Increasing pollution not only causes serious problems such as global warming but also could threaten to end human life on our planet. On the other hand, man exploits and abuses non-renewable energy and resources for the sake of developing economy. If man insists on extracting natural resources recklessly, it will be too dreadful to face the consequence.
　　Let us remember that only when we shake off greed and heal the earth can we build a better home for ourselves and our future generations.
