For decades, plastic bags have been staples at grocery stores. They also clog drains, cause floods, litter landscapes and kill wildlife. Consequently, a growing number of cities and counties have passed laws that ban or tax plastic bags in the past ten years.

Sales of trash bags — which use more plastic than typical grocery store bags — jump after plastic bag bans or taxes are implemented. And other alternatives — like paper bags and canvas totes — are even worse for the environment.
