As an iPhone 4s user, I can tell you how "hard" my life is because all my friends have the iPhone 5 or better. And yes, I DO really want the six, but have you ever taken the time to see how the usage of your cellphone affects your carbon footprint? According to http://fatknowledge.blogspot.com/2007/0 … hone.html, in an article dated in 2007, manufacturing a cell phone uses about 1390MJ of energy and produces 60kg of carbon dioxide emissions. Yes, this is somewhat of an old article, and because the phones were less technologically advanced, the amount could have changed drastically if we used cell phones as much as people did in 2007. Think about it. Not all of us were old enough in 2007 to have a cell phone (me included), but how much more do your parents or guardians use their phones now than you remember them doing so when you were younger? For me at least, A LOT.

The use of cell phones contributes a lot to the universal carbon footprint, but has become a sort of global necessity. Without his phone, I don't think my dad could do the job he h as and loves. In my case, the iPhone 6 is a want, but in my father's, his phone is a need. In his situation, reducing use of his cell phone is "off the table" because that is a major factor in his job.

As a teenager, I use my phone all the time for useless and pointless things such as Instagram and Snapchat. Reducing the use of my cell phone is not "off the table" for me, so I urge all of us who have cell phones to cut down our usage to help keep universal carbon dioxide emissions down.

I definitely agree with you. As teenagers, we use our cell phones for the most unnecessary reasons. My parents and their friends use their phones a lot more now, too. I looked at the website and I'm shocked at cell phones' contribution to the universal carbon footprint. I agree that people who actually need to use their phones should use it. But, teenagers don't really need their phones. They think they need it, but it's honestly not that hard to go a day without your phone. We all did it at the retreat. I've done it several times by choice, and it was not torture. I thought I was addicted to using my phone, but it actually was relieving not using my phone. If I can do it, I'm pretty sure other teenagers can to.

,too*. Sorry for my grammatical error!

I agree. As a student, using your phone and its data primarily to take pictures and to get on social media is a rather unnecessary addition to every individual's carbon footprint. We should all look at exactly what we do on our phones and try to cut down on things like social media and pointless games in order to reduce the environmental impact that results from us using our cell phones.

I actually went a whole year without my phone and it was AMAZING.  Not only did I notice my grades improve, but I saved a ton of money from not having to use it on a cell phone bill.  Along with you guys, I'm also surprised that cellphones contribute so much to the carbon footprint.  I now have a phone again, and I'm actually surprised how dependent I'm on it now.  Thank goodness I have no cell reception in most of my classes (haha).  I'm definately going to start turning it off now when I sleep and try to only charge it once per day.
