I personally believe that cell phones are necessary in our modern day society, but not always. Cell phones can have many benefits, including communicating in emergencies, staying in touch with people and much more. However, I do not think it is necessary to buy a new phone each time a new one comes out. Buying new phones often contribute immensely to carbon dioxide emission that can effects the Earth in harmful ways. Being on your phone constantly can also contribute to CO2 emissions. Apple and other cell phone companies are very good at luring us into buying the newest phones when we do not always need them. A way to reduce your carbon footprint is to spend less time on your phone and only buy a new one when you actually need it. It is important to be ware of the impact cell phone usage and purchases have on the environment.

I agree that it is unnecessary to purchase new cell phones and people should spend less time on their phones. However, purchasing a new cell phone is insignificant to our footprint. Purchases contribute about 100-300 kgs of CO2 to our annual footprint. Purchasing cell phones alone will have a very small impact on your footprint. As for devices consuming electricity, it is estimated that the average cell will only consume 1-2 kilowatt hours in an entire year, or about 25 cents worth of electricity. Therefore cell phone purchasing and electricity consumption is very insignificant compared to other emitters such as cars, home appliances, and food.

I agree that cell phones are necessary in our modern day society, but not always. It isn't the phone that consumes a lot of energy, but it is the networks they relay on. If you want to reduce the footprint of your communication habits, texting is a much lower-carbon option. Also Landlines offer carbon savings, too, because it takes about one-third of the power to transmit a call over a fixed landline network than it does when both callers are on a mobile. I think if we cut down the amount of use of our cell phones, or use landlines, our carbon footprint will be way better.

I agree cell phones are needed for safety reasons but there is a big over usage of them. If we limit the time we spend on cell phones it can reduce the footprint of energy usage. Also charging phones at night isn't healthy and consumes lots of energy it also makes the battery worst, finding another time to charge your phone will also help save energy and reduce footprint.
