各位大侠，求你们帮我写几个用电脑的坏处（英语）只要几个观点就行~不要网络的~

The most controversial problem with computer is to what extent the computer can help improve the civilization of our community.
The computer also takes the blame of real-world crime since the violence and blood in computer game.
Another bad spot is the trend people are used to typing by keyboard instead of writing by hand.
Thousands of tons of free information online makes lots of media workforce lose their jobs.
自己写的，没有抄写，如有错误请指正。

我英语很菜.........
