You're a purist, Virgo, so use homemade cleaning products like diluted vinegar for streak-free mirrors, baking soda to scrub the toilet or a banana peel to polish your leather shoes. Feed your pets organic food. Buy locally grown produce, which saves on long-distance trucking fuel.

Better yet, grow your own food and compost the remains, or join a neighborhood co-op garden. Cater to your fastidious nature while camping with a portable, environmental toilet.
