Hi, Thanks for comment, certainly the technology has an environmental price that affects us. Unfortunately the obsolete technology happens very fast, and its replacement consumes and degraded part of our environment, causing that the impact on paper saving is not perceived when repopulating the trees to maintain our environment. This situation is comparable with the use of solar cells in substitution of fossil fuel, where the improper disposal of the batteries that require this system cause more damage and environmental contamination than the fact of not using it.
