EVERY THING THAT IS REQUIRED TO SUSTAIN OUR LIFE ARE FREE GIFTS OF NATURE - e.g. AIR, WATER, SUN LIGHT:

No sooner man starts to manipulate and tries to profit from the free gifts of nature, the eternal fight / struggle for hoarding and depriving fellow human being sets in and ultimately ends up in destructing. All the wars in the recorded history, though might have an apparent look as if they were started for some religious or philosophical purpose, but an in depth study will prove that they all have one common reason behind it and that is hoarding and deprivation. Say for example USA went to Iraq with the plea that Saddam was a bad man in the world politics and that USA will give Iraq DEMOCRACY, but the real reason is to control the huge oil reserve of Iraq. In Afghanistan they want the gas pipe line from Asia Minor to run through all the way to a port in the Arab Sea.
In fact one guest in CNN on the topic of World Energy had the guts and audacity to say that the Oil and Gas in the Middle East belongs to USA but it so happens that they are in the Arab lands, so the Arabs have far less claim on it than the oil exploring companies of America.
One can not help but recall why Dr. Mosadegh of Iran (a graduate from US university) was replaced by a Monarch with the help of UK and USA(CIA) in 1953 - once again to have full control of the oil and gas reserve of Iran.
Back to the topic of FREE BOUNTIES OF NATURE:
One simply shudders to think if one had to buy the air that he inhales or the sun light that he needs or water that he consumes. Think Bill Gate's net Worth or income could sustain the consumption bill. Even the most basic pleasure of the bliss of marital sex is a free bounty of nature - please don't simply laugh it out or ignore, but ponder up on this objectively and you will see how benevolent nature is. Not only that it is benevolent but, it does not keep a tab of individual consumption, so long it is for pure consummation purpose. The point of contention starts as soon as the hoarding and deprivation (the eternal tug of war) snick's in.
