True happiness comes from having a sense of inner peace and contentment, which in turn must be achieved by cultivating altruism, love and compassion, and by eliminating anger, selfishness and greed.
Peace and the survival of life on earth as we know it are threatened by human activities which lack a commitment to humanitarian values. Destruction of nature and nature's resources result from ignorance, greed and lack of respect for the earth's living things.
Many people and companies only have one goal: money, money, and more money. Greed is ok when you let others profit from it, but greed for oneself is bad, it makes you ill.
If we human beings rely only on material development, we can’t be sure of a positive outcome. Employing technology motivated by anger and hatred is likely to be destructive. It will only be beneficial if we seek the welfare of all beings. Human beings are the only species with the potential to destroy the world. Because of the risks of unrestrained desire and greed we need to cultivate contentment and simplicity.
One interesting thing about greed is that although the underlying motive is to seek satisfaction, the irony is that even after obtaining the object of your desire you are still not satisfied. The true antidote of greed is contentment.
