Something big is happening to the human race, something that could be called the Great Transformation.
The Transformation consists of all the changes that are occurring in human life due to advancing technology. For thousands of years such progress occurred slowly. Now everything is changing so fast that you may find yourself wondering where all this progress is really leading.
Nobody knows what all these changes will really mean in the long run. But this mysterious Transformation is the biggest story of all times. It is the story of the human race itself.
Some people worry about what will happen when the deposits(蕴藏)of petroleum are gone, but already researchers are finding all kinds of new ways to get energy. Someday, solar power collected by satellites circling the earth or fission(裂变) power produced by mankind may give us all the energy we need for an expanding civilization(文明).Space exploraton promises to open up much new land for human settlement, as well as leading to the harvest of mineral resources.
Like it or not, our advancing technology has made us masters of the earth. We not only control all the other animals, but also reshape the world’s plant life and even its soil and rocks, its waters and surrounding air.
Technology gives us the power to build a great new civilizaion, if we can just agee on what we want it to be, bu today, there is little global agreement on goals and how we should achieve them.
So it remanins to be seen what will happen as a result of our technology. Pessimists(悲观主义者) worry that we will use the technology eventually to blow ourselves up. But they have been saying that for decades, and so far we have escaped. Whether we will continue to do so remains unknown, but we can continue to hope.
