Our green guru, Danny Seo, shares a simple way to show someone you love them while loving the planet.

In just a few steps, you can recycle a glass bottle into a Valentine’s message-in-a-bottle. Save feathers, cookie fortunes, shells, white sand, and other mementos to add to bottles. Use pins or thin wire to hang love charms and delicate paper curlicues. Write “I Love You” on an office supply price tag and tie around the neck of the bottle before giving to your special friend.
