The message behindThe Human Elementis chillingly clear—global warming is upon us, we’re at the center of it, and here’s why we need to do something about it. In this documentary, James Balog, an environmental photographer, explores the four basic environments on Earth: earth, air, fire, and water.

Each element is its own chapter, essentially. Air, for example, focuses on air pollution, such as the burning of fossil fuels like oil, coal, and natural gas. More importantly, each “chapter” is not only meant to highlight the problem, but present solutions as well.

2040is one part informative and one part hypothetical. Part of the documentary is dedicated to showcasing existing technology and solutions that are being used right now to mitigate global warming, like solar panels and regenerative agriculture.

The other part of the documentary is then dedicated to imagining what life on Earth would be like in 2040 if we were to adopt the solutions seen in the film and how it would impact us on a global level.

David Attenborough: A Life on Our Planetis both touching and informative, but it also doesn’t shy away of what global warming does to Earth, how it affects ecosystems, and the alarming decline and disasters that humans exasperate.

However, it’s also a hopeful documentary—an urgent message to humanity that we can fix the problem, work with nature, and create a natural balance with the planet.

Space is part of our environment just as much as the ground beneath our feet, andCosmosaims to bring the mysteries of outer space to us. It’s a series that started way back in 1980 and was presented by Carl Sagan (who also had a hand in its creation, alongside Ann Druyan and Steven Soter).

However, the series' follow-up,A Spacetime OdysseyandPossible Worlds, features Neil deGrasse Tyson, another famous astrophysicist. All three documentaries are a fascinating look into how space can affect Earth, as well as push against anti-science opinions.

Who doesn’t love elephants? Unlike other documentaries that gloss over these creatures,The Elephant Queenfocuses entirely on a herd led by Athena, a 50-year-old elephant, and shows the delicate balance elephants live on.

It’s a fascinating and captivating look into the lives of elephants, like their herding habits, surprising intelligence, their young, and the ecosystem they’re a part of. It’s also narrated by actor Chiwetel Ejiofor (12 Years a Slave, Doctor Strange, The Martian).

1 hour 37 minutes

I Am Gretatakes a much deeper look into climate activist Greta Thunberg, starting from her first strike at 15 years old to her speaking at the UN Climate Action Summit in New York just a year later.

More often than not, group strikes are what get media attention, so it’s impressive and inspiring to see how muchjust one personcan spread the message and urgency of global warming.

Planet Earthshould be the crowning jewel of your Earth Day celebration. It is arguably the most important, given that it does an excellent job showcasing just how diverse life is on Earth. Every animal shown inPlanet Earthis one more reason to take care of the planet.

What’s particularly interesting is that at the end of every episode, you get to see just how difficult it was to capture the footage used in the documentary. Some of the shots the crew captured are incredibly clever!

Many of these environmentally-friendly documentaries will leave you in awe during Earth Day (or any day, for that matter), so be sure to have a box of tissues nearby for the inevitable tears.
