　 Modern people can no longer return to the original path of the wild animals and not to mention that people simply do not want to admit this reality. Things are objective while knowledge is subjective. People always do not want to accept or take the attitude of rejecting or resisting for the things they do not like, while look forward to hope those they like. Even if the things they like do not exist, they would rather believe they do, which is an important reason why so far the human beings have been unable to see the direction they are going to. Hundreds of thousands of years ago, the invention and creation of our ancestors have brought us from the apes’ times to today. In the future, where will the science and technology take us to? Whether we have courage to face this problem or not, as it is the most realistic and most pressing issue that is placed in front of the humans.　

　If this problem is recognized, the next question we face will be "How to do?”. This is no small problem, and it is by no means to give up all the existing things to completely return to the state of wild animals millions of years ago. This is not only because we cannot do so, but also because the evolution of the road is irreversible. Therefore, returning the original road is simply impossible. What we need to consider is how to find a "sustainable development" road that not only keeps good things existing in the civilization, but also to avoid leasing ourselves to destructions.
