One of the best obstacles dealing with mankind is to find a method to lower our dependence on unsustainable resources, like fossil fuels. Many, if not all, contemporary industrial societies rely far too greatly on fossil fuels and increasingly, this is becoming an undeniable reality. Wars of conquest are being waged to secure what is left of the world's oil reserves. As opposed to driving a war maker bent on controlling the oil markets if only the resources of the effective countries were carried into establishing sustainable energy options. Our contemporary lifestyle is going to go through some hard times in the really future, if this truth continues to be ignored. Ask yourself what you can do to make a distinction. You may be amazed at what you can achieve.
