The Problem: America has a huge appetite for comfy toilet paper. But what's good for the tush isn't good for the environment—soft toilet paper doesn't contain any recycled material and is often made from old-growth forests. A waste expert called soft toilet paper "a lot worse than driving a Hummer" in terms of environmental impact.

The Solution: Europeans use toilet paper with a greater proportion of recycled fiber. But there's an even more environmentally friendly solution—reusable toilet wipes made of cloth that can be washed and used again. Gross? Maybe. But one manufacturer promises they don't stink.
