Most paper uses a very decent amount of recycled paper, has ti actually. To the point the industry faced issues last Q1 when demand went down and there wasn't enough recycled paper on the market. Trees are grown explicitly for paper production, and are regrown in the same forests. Net forest losses are mainly due to farming, e.g. in the Amazon region. Energy wise, paper production offers great opportunities to balance the grid.
Most paper, at least in Europe, is actually recycled.
And electronics do have there issues as well. They consume raw earthes, are consumed as well, end up in land fills and also have quite extensive supply chains and CO2 foot prints. And they consume electricity, which has to produced. And we are nowhere near the necessary levels of renewables.
I do support getting rid of useless paper consumption, it just not as straight forward as it seems.
