Leaving Computers on Over Night

This was one of the habits that I identified while shadowing a wasteful friend. He would leave his computer on for most of the day then over night to download anime or something. A lot of the time he would leave the light on too (which is an other habit, but this one happened because it was the computer room). He could go away for hours even out the door and just leave all the stuff on. Most people are probably not that bad, but still to some level this happens quite a bit. What people don't know is that when computers are running, they also off gas CO2. Every year millions of tonnes of greenhouse gases are released by them. This does not only sit badly with the environment but also the user as well, it creates a toxic space to be around. So remember to turn off your computers when you don't need it for you own good literally.
