It seems that toilet paper is being hoarded everywhere! Even in Ontario, Canada, that's covered in trees, where most of the stuff comes from, the Premier has to beg: After we wrote "Can't find any toilet paper? Get a bidet" the genius PhDs and mathematicians at Omni Calculator whipped up a toilet paper calculator to tell everyone how much toilet paper you actually need; it is less than you think. The calculator takes into account the size of your family and the size of the wad of paper you use. At my suggestion, they added a calculation of how much water and wood is consumed making it. It's a lot more than you think. See a prettier version of the calculator here or the embed below, and stop hoarding! Toilet Paper Calculator
