I’m always telling people, “You can’t just buy green. You have to consume less.” But gee, there are some fun products out there, like the plantable postcards (they contain seeds) from the USPS. Find the postcards and check out some fun family activities at the USPS Go Green page. They’ve designed a series of 16 Go Green stamps too to encourage ride sharing – buy them and learn about the post office’s commit to sustainability at usps.com.
