Really, all this says is "microplastics that fall on soil stay in the soil", but, you know, could be worse?

Actually, saturated soil weighs around 100-120 pounds per cubic foot, which is comparable to concrete (150 lbs/ft³) and much heavier than most people realize - thats why proper structural engineering for green roofs adds significant cost to building projects.
