Paper or Plastic? used to be the question at the supermarket. But unless you've been in a coma for the past few years, the answer is steadily becoming neither as more people are moving to reusable grocery bags.
And what's wrong with the plastic bag? Well, first, it's made of petroleum, a non-renewable natural resource. If we have a resource that of limited supply and we're depending on that resource for transportation and growing food, why squander on making bags to carry our groceries. And the option of paper bags carries even heavier consequences.
