It depends on how small you write, I suppose.

If you just want people to die, you can put down quite the massacre on both sides of an A4 page.

However, if you want people do to specific things before they die, like billionaires redisteubuting their personal wealth, or steer world leaders to reverse a lot of their bullshit, you’re going to have to get very creative with your wording to optimise as much page space as possible.
