When you think about how you can take steps to lighten your environmental impact, you might consider things like declining plastic strawscomposting your veggie scraps, biking to work, or bringing your own reusable bags to the grocery store. But you probably haven’t given a whole lot of thought to switching up your toilet paper. After all, you kind of have to use it, and you might assume that it’s all pretty much the same.

But the truth is, our use of conventional toilet paper is contributing to deforestation, according to a recent report from the Natural Resources Defense Council. That’s because the bulk of toilet paper sold and used in the United States is not made from sustainable or recycled materials but instead from virgin wood pulp that comes from centuries-old trees grown in the Canadian boreal forest. (Worldwide, it’s estimated that the equivalent of about 27,000 trees are flushed down the toilet or tossed in the trash every day in the form of conventional TP.)

So what’s a good alternative? In addition to any TP made with a high percentage of post-consumer recycled materials, bamboo-based bath tissue is a great choice. Here are five highly rated bamboo toilet paper brands that will lighten your environmental impact—some of which also have pretty impressive philanthropic efforts (and look really great in your bathroom).
