You probably know about 4ocean's bracelets already; they fund ocean cleanup efforts, and are made from the resulting recycled materials. I wasn't always aware that they have quite a lot of variants of that bracelet (more available online than you'd ever see in your local brick-and-mortar hippie store) and that you can sign up for subscriptions.

It's also less widely known that they have some fancier jewelry as well, and some other items similar to what you'd find in other sustainable-living stores, including the same ZWS Essentials brand that EarthHero carries.
