Earth Day 2021: The best documentaries available to stream on Disney+, Netflix, Prime Video & Apple TV+

Today (22nd April 2021) marks the 51st anniversary of the internationally celebrated Earth Day and I’ve picked out some of the best Earth-inspired documentaries currently available to stream.

What is Earth Day?

Earth Day is celebrated across the globe with a focus on pledging support for environmental protection. Every year, Earth Day has a dedicated theme and this year’s theme for Earth Day is ‘Restore our Earth, focusing on natural processes, emerging green technologies, and innovative thinking that can restore the world’s ecosystems.

Secrets of the Whales

To mark the occasion of Earth Day, Disney+ in conjunction with National Geographic have released a brand-new series focusing on some of the most magical sea creatures on Earth, whales. Each of its four episodes focuses on a different species of whales and explores their mysterious and beautiful worlds. Oh and added bonus, the series is directed by film-making legend James Cameron and voiced by Sigourney Weaver!

Earth Moods

Another recent release from Disney+ is the National Geographic series, Earth Moods. Similar to Secrets of the Whales, Earth Moods is split into 5 episodes with each individual episode showcasing different landscapes from all corners of the world. Disney+ say that “each ‘mood’ gives the audience an opportunity to relax and reset as the sounds of music and natural world washes over them” – perfect viewing after a stressful day by the sounds of it!

Seaspiracy follows an independent filmmaker as he sets out to document the corruption and devastation in the fishing industry. Whilst the documentary is at times heart-breaking to watch, it’s documentaries like Seaspiracy that provide such an eye-opening look at the desolation being caused behind closed doors. The documentary has caused a lot of controversy since its release, but no one can deny how thought provoking it is.

Our Planet

David Attenborough is undoubtedly a legend in the world of conservation and Netflix original series Our Planet is one of his best documentaries to date. Our Planet offers some of the most stunning visuals of any documentary I have ever seen and if you are a fan of the award-winning BBC documentary series Planet Earth, then our Our Planet is right up your street. It’s also possible to watch the entire Our Planet series for free too! Earlier last year, Netflix made the whole series available for free on YouTube.

Bugs: Nature’s Little Superheroes

Maybe one to help you overcome your fear of creepy crawlies! Bugs: Nature’s Little Superheroes is a docu-film exploring how tiny insects could be used to combat some of science’s biggest problems – from producing biofuel to killing drug-resistant bacteria and curing cancer! Insects are the most diverse species on the planet and it’s about time we shifted our view on them.

Tiny World

Considering the limited selection of content on Apple TV+ as a whole, it actually has a few surprisingly brilliant documentaries. Tiny World is a docuseries showcasing nature’s lesser-known tiny heroes including species of insects and amphibians and is narrated by the brilliant Paul Rudd. I wonder if the series looks at any ants?

The Year Earth Changed

Another documentary narrated by the conservation king. David Attenborough narrates The Year Earth Changed, a very topical documentary looking at how humans living in lockdown has opened the door for nature to bounce back and thrive. Given this year’s Earth Day’s theme is ‘Restore our Earth’, The Year Earth Changed seems very fitting.

Hopefully watching any of these documentaries will leave you feeling inspired to help protect and conserve the Earth this Earth Day.
