Because a $99 tablet is cheap, as in garbage, and not worth the energy put into making it. Trees get re-planted by the paper companies usually 2-to-1 or 3-to-1 when harvested.
I hate when people ignore simple facts.
This is a false propaganda to shut people up - they are all re-planting.
Overall, a lot more trees are disappearing, than get planted each year (ratio is still alarming, at about 150km^2 every day). Every piece of paper counts, and people who don’t care about nature, are the primary cause of degradation, and people who print that ONE more page, which doesn’t need to be printed, simply don’t care - no excuses, this is a game we talk about here, not a life saver. What are you gonna do when the game stops working, which will happen eventually. Are you going to bin the manual, or keep it forever and ever? In a tablet, you can simply delete it, with no harm to nature.
Also keep in mind that a lot of energy is going into paper printing.
Maybe $99 is not the best to buy, but it was just to point out that people should change habits sooner than later, and stop being stubborn and selfish.
