The Importance of Cooperation

As is shown in the vivid drawing, the two disabled men leaving their stricks through (not sure what you meant here) assisting each other. It's hard to image the life with stricks (still not sure what this is), but cooperation has made tomorrow a brighter day.
The drawing illustrates the importance of cooperation. We can never forget the Wen Chuan earthquake forever. The suddenly shake destroyed the everything in an instant. It took cooperation from all of China and many friendly countries all over the world to help China weather the historical disaster. It's hardly to restore the economy and reconstruction so quick if there is no cooperation.
The human race has entered a completely new state in It's its (it's means it is, its is possesive) history with the increasingly rapid economic globalization and urbanization. Cooperation has become a common topic. China is actively embracing with other nations in every fields and we are doing our best to provide help for a mutually beneficial cause the win-win. In conclusion, no cooperation, no life without cooperation there can be no life.

I'm not sure what you meant by stricts and parts of the passage still sound strange.
