From notcot.com: "Born out of the desire to do right by the planet, this year Pangea Organics has a great gift idea to let you in on the fun, too! After two years in development, Pangea just released a series of holiday gift boxes that actually grow Spruce Trees. Yes, that's right. Just like their plantable packaging that grows organic, edible sweet basil, the box itself grows a tree. Just soak the box for a day, and plant it in the earth. If everyone plants their holiday gift box and bar soap box this year, collectively, we will have planted 122,000 trees which is equivalent to not driving 30 million miles in one year! Multiply that out by 75 years, the average lifespan of a Spruce, and that's 2 billion, 250 millions that we're collectively offsetting!"
