Now days for teenagers having the latest phone is always very nice because higher quality pictures for instagram and faster internet so you can watch videos faster. In reality the new phone is not even much of an upgrade it is just most teenagers are addicted to there phone and always have to make sure it is near them or in there had or else you feel stressed out or like some people say "naked" without it. I am guilty of this as well and it is very hard to stop being on it so often. But getting so many phones can have a toll on the environment and keep getting new ones that you do not always needs pollutes the world even more because electronics take a long time to go away and the batteries are bad for the Earth. So try to use your phone even when the new upgrade comes out to keep the environment a little better.
