I think people doesn't need a lot of electronic devices. We'd never needed them to survive, but now it seems we can't live with our old electronic devices and we need to have the newest and the best of the best. I barely change my phone and stuff like that so often because I think if what I have is still functioning, why would I need something else?

I agree with you. If we learn to reuse and repurpose our materials we will cut down on our pollution of the world. However, we as humans need to do a better job of maintaining this reuse and recycle mentality. An example of this is plastic recyclable bottles. Every time we recycle that soda bottle we like to think it becomes a new soda bottle. However, a news site made an article on the reuse of plastic bottles. Newser states, “Less than a third of the world's plastic bottles (around 6 billion pounds per year) are recycled, and of that sample, only about 20% is transformed into new plastic bottles. Instead, most of the bottles are sent off to plastics factories in emerging markets, where they're used in textiles such as clothing, bags, and carpeting, and the reason appears to come down to cost.” This is shocking because not only are the bottles not recycled as often, 80% don’t go to remaking bottles.
