Instead, what is happening is that the integration of 2.5 billion people (China and India alone) into the global economy is producing a demand shift that is likely to put far more upward pressure on commodity prices than any technology gains are likely to offset. So, for at least the next 50 to 75 years, and perhaps until humans start mining on Mars sometime in the coming centuries, prices for many natural resources are headed up.
世界并不会耗尽原料。实际上，25亿人口（仅仅是中国和印度两国）融入全球经济，其产生的需求移动带来的对原料价格的上浮压力要远远大于技术进步所可能抵消的部分。所以，在未来50到75年的时间里，甚至未来几百年人类开始在火星采矿之前，许多自然资源的价格都会上扬。
