Technology is very useful to the earth. An example of a piece of technology is an iPod. Having portable music is useful and helps a lot of people in a lot of different ways. One way is that when people workout they usually listen 2 music 2 occupy themselves. Another great use for an iPod is 2 get your mind off of stuff. A lot of times people listen to music to get their minds clear of everything that’s going . When people get their mind clear they r usually happier. So I think technology is very useful to the earth.
