Here is the three topic that I am most interested in:

Transportation:    Transportation is effecting us by allowing us to travel far but have effected lots of traffic. Also hybrid cars effects few of global warming.

Impact on life:    Fast paced game [example: Call Of Duty] has impact on your brain because if you play them you can rapidly move or see or trace fast things then the people without playing them

Communication:    Communication have effected us because now we can trace other people or talk to far people with the antennas.

The most appealing topic to me is Transportation because I want to learn a lot about hybrid cars and polutions. The question that left me with is:
Now I understand that video games are good for you in a way but what about the the screen problem?
Doesn't the screen still make your eyes bad?
