Christians believe in the "creation mandate". These believe that since God created all that is, humans are responsible to be responsible. It is no less true for the scientific materialists. These also believe that one must dominate and steward the earth's resources. Therefore, there has been an alliance of purpose, so that the world, or globalized efforts will "come into being". But, is 'one purpose' the best way or best option among options of "leading the world"?
Science in the West has been useful to bring about a better way of life, in quality to health, and comfort of lifestyle. We believe that science gives us opportunities to explore and discover yet to be known facts about our physical environment, so the the earth can be its best in serving mankind's needs.
Christians, and other faiths, also believe that the earth is of value to protect. Therefore, the environmental movement, from global warming to recycling has impacted the globe, whether believer or unbeliever. "Avatar" is only one amongst many sci fi movies that feature American interests in science, environment and "mystery" (the yet to be discovered).
"One world" can come about through such goals and visions of stewardship and dominion. But, in our world of global conflict, ideological differences, is it going to bring about "the Kingdom of God", "peace on earth", or "Utopian dreams"?
With limited resources, and within limited means of bettering the world, how are we to envision that all will have equal? or live under equal protections of "law and order"? Is duplicity a means to that end? And what of those that are duped under such means? What is the real purpose of the law?
It becomes clearer as the West has opened its doors and heart to those "without", whether national identity or social and economic means, that the world is much too complex to hope for "utopian ideals". Laws define the boundaries around national identity. And laws conflict when ideology conflicts. This is why some in the West are frustrated by Islam's demand for special consideration of their laws. The U.N. has acquiesed. And the West is suffering under what to do with Shairi'a.
This is not to say that those that have "hearts of gold" or seek to "sainthood" should not seek to do good, waiting for a reward later, or whether they just don't "miss" the funds they send because they have so much anyway.
I just oppose those who want their visions to be everyone's. Stewardship and dominion must be held, defined and expressed within different value systems. Stewardship may mean for those without the ability to give to the poor, that they don't buy the "Coke", so they can afford the formula for the baby at home. And for those who have so much, well, they are free to give as their hearts desire, because they won't miss it anyway.
Dominion of the earth and its "goods" is a way of viewing leadership in honing the earth's resources to better mankind. Scientists have the ability to dominate the earth in the way their specific expertise designs. But the personal commitments, and values of individual scientists, will determine how that will be lived out in their lives. There is no "one way of being in the world". It is a matter of commitment, choice, and value. And it is a matter of life, liberty and the pursuit of happiness.
