How about getting dad that new grill? Did you know that electric grills release 99% less carbon monoxide and 91% less carbon dioxide than charcoal? That's pretty great!
Maybe add a bamboo cutting board to the list? Did you know that this sustainable wood is 16% harder than solid maple? Bamboo is far more renewable than plastic, and it's low maintenance -- just clean up with a quick rinse.
If you insist on the tie - why not get your dad a wallet made from recycled neckties? Smart looking and a great reuse for an old tie!
It's not easy being green, but maybe these gifts might inspire you or your dad to be just a bit greener! Happy Fathers Day!
