To begin with, one positive aspect of teaching pupils subjects in digital format is preserving and protecting the environment as one critical issue which produces greenhouse gases. Indeed, with the growth of the publishing industry whose raw materials are supplied from forest trees, so did its carbon footprint. In other words, by providing circumstances in which students will be able to learn through media and new methods paper consumption will reduce significantly. In addition, this reduction prevents trees from being cut down as well as emitting of co2. According to some studies conducted recently, just over 5 million trees would be saved if industries have a 30 per cent decrease in paper utilization.
