When biohazard* breaks out, which way would you like to kill the zombies? Of course it is just a science fiction movie, but recently, more and more people begin to worry about crises, or their post-apocalyptic future, brought by what we have created such as high-level technology or sophisticated medicine. So it seems that progress don’t always bring us good things..
Claims that we are the truly miracle in the evolution have became widely publicized. According to the anthropology, Paleolithic society was more primitive than we could imagine. Contrary to us today, as food gathers, people at that time have to concern about their life because the starvation and killing by beasts were normal. However, even in that situation, people still acted as brothers by sharing their food and providing defense for each other. On the other hand, in that human civilization was still very original and lacking for both manpower and resourse, large-scale war would never become possible until the rise of agriculture. However, many morden people seeking for profit are avaricious and egotistic, betrayal and lie are common in present world, and some injustice war fired in some corners. With the glorious evolution of human, cupidity has filled this society to replace that truly utopian life in origin.
What’s more, beside the crises of humanity, we damage our planet as well. Not only did the Industry Revolution in 20th century brought us steam engine, combustion engine and electronic power which made the extremely development of economy come true, two these industrial progress left tons of thousands of carbon dioxide in our atmosphere and millions of extinctions in natural world as well. These crises caused some other natural disasters like flood, tunami and tornado. And in many cases, with the rise of sea surface, some contries even rang the red alert and emigrated in other places. Title to these progress could be claimed on the basis of destruction of environment, obviously, the development of economy is not always meaning prosperity and harmony.    
Of course, although progress does not always bring us good things, but the prupose of development is always the same type: to create our happy life. Furtunately, taking advance of high techonology from all over the realm, people are confident to face these unprecedented challenges together. And we believe someday, we can reach the level without disputes.
