Christine16,<br /><br />Can one hope that there will be no dominant space power in the quarter century between 2025 and 2049? That perhaps an era of true international co-operation will come about, allowing the financial power of China to be coupled with the launch expertise of Russia and the technology of the United States? If such sharing of resources were to happen, progress in off planet exploration and development would eclipse anything seen so far. Realization that this adventure is not about national pride, but survival of the species would help. <br /><br />Finite resources, a limited capacity for the ecosystem to cleanse itself of the waste that we dump into it, and desire for higher standards of living by billions of people is a recipe for disaster. Imagine if all the world lived as the United States does. Can't imagine it? Probably because it could never happen, given the way that the United States squanders energy, ignores the consequences of greed, and demands the incredible luxury of personal transportation for every trip.<br /><br />But there is a way for everyone on this planet to enjoy the benefits of technology, such as living indoors, eating, and traveling further than 5 miles from the place of ones birth over the course of a lifetime. By utilizing the resources of the Solar System, outside of the Earth's ecosystem, we can mine metals, smelt them down, cast them into lightweight foams, and send to Earth products which can never be produced economically here.<br /><br />Much of the wealth that the United States enjoyed in the last century came from extracting resources that no one else claimed, and turning those resources into goods which other countries could not produce themselves for a comparble price. The frontier on the other side of the sky offers the promise of wealth many, many times what the United States breifly enjoyed. Making that wealth a reality will come much sooner if we work together, rather than treating each other with suspicion <div class="Discussion_UserSignature"> The secret to peace of mind is a short attention span. </div>
