Forget what Kermit the Frog said with all of that “it’s not easy being green” nonsense. Being green is as easy as taking that just-emptied jar of mayo, giving it a good cleaning, and reusing it. Maybe you could use it to store a homemade teriyaki marinade. Or maybe you could turn it into a makeshift piggy bank to hold all of that loose change. It really doesn’t matter. There’s no need to throw it away or, heck, to even toss it into a recycle bin. Recycling uses electricity too, you know.
