我们必须考虑每一项技术进步对环境的影响。
The world is a beautiful place, but it has its thorns.
The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.
"We are all victims of our own illusions."
