How Can We Fight Injustice?

As the proverb says, "The pen is mightier than the sword." I really agree with this statement, especially when I live in a high technology world with computers and the Internet. There are many injustice on the world that we cannot solve (global poverty etc.), but we still can express our ideas by speaking or writing out our ideas. To me, I think works both spoken by mouth and written by hand are both very powerful. People can publish their works by blogs, newspaper, television, radio, or magazines. These are all common "places" that people constantly visits. Most people orders newspaper and watch television everyday; some listen to radios when they are the car; many read the magazines monthly, weekly, or even daily. These are all very power sources that can provide people to publish their work. However, among all of them, I think the best way to let people notice your work is to publish on the Internet so every person in the world can look at it and know what you want to say. Although this may not solve the problems, it still can let your thoughts be noticed.
