To begin with, teacher's spend too much time and effort correcting homework. On average, a teacher teaches about 3 grades, each grade is divided into three sections, and each section includes 20 girls at least. If you do the math, that's at least 180 students. One paper would take the average of 15 minutes to correct and mark. Meaning that if the teacher had one week to correct all the papers for all 3 grades, she'd have to spend 6.5 hours every day for 7 days. Keep in mind that most teachers don't only give one homework a week. On top of that, most homework is done on paper, and it's almost always handed back to the student, it would usually end up in a trashcan. "Most homework does not actually benefit the student," Edward Abbey, writer and wilderness activist, stated when asked for his opinion on how much paper is wasted on homework, "It is only a hassle for the teacher to move around and a threat to our environment,"
