Other than planting a tree, donating to your favorite charity, or, you know, not littering, the best way to celebrate Earth Day is by enjoying Boomerang’s free weekend preview of the ’90s cartoon classic Captain Planet! The animation-based streaming site has made the first season of this beloved eco-friendly series free to stream from today until April 22nd.

Premiering in 1990, Captain Planet was an educational superhero series featuring a quintet of teenagers who work together to encourage environmentally responsible behavior and thwart various pollution-loving bozos from causing ecological disasters. That’s about it. Oh, wait. Right. Gaia, the spirt of the Earth voiced by Whoopi “Sister Act 2: Back in the Habit” Goldberg, also sends five magical rings that separately control Earth, fire, wind, water, and heart to five teens across the globe (the Planeteers). When they combine their powers, they summon the man, the myth, the environmentally friendly legend: Captain Planet.

The show does a succinct job of explaining this in the pilot episode.

“Let me get this straight. Your name is Gaia and you’re the spirit of the Earth? And you brought us here to help you save Earth from being ruined?” the Planeteers asked. “Yes, that’s about the size of it,” Gaia replied, rather glibly. Although in Gaia’s defense, she’s seen it all during her time protecting Earth.

The series, which can be described as your coolest middle school teacher decided to make a TV show, also features a memorable theme song ’90s kids know by heart.

Captain Planet also featured a slew of celebrity voices including Jeff Goldblum, LeVar Burton, Meg Ryan, Martin Sheen, and Sting.

The best part of the free preview? If you stream Captain Planet this weekend, you’re actually doing your part to help save the Earth. “The more you watch, the more we donate,” Boomerang noted in their press release. “Stream all 26 episodes and help us give up to $50,000 to the Captain Planet Foundation. By your powers combined, we can support the Earth!”

Perhaps we can finally take pollution down to zero. Goooo Planet!

You can stream Season 1 of Captain Planet on Boomerang.
