David Attenborough is back with a new amazing and shocking documentary about our natural world, and like all Attenborough programme, it has left some fans bewildered.
Not only that, Netflix original series Our Planet has absolutely tugged on viewers' heartstrings as it shows the stark reality of the mammals losing their habitats as a result of global warming.
In the series, viewers get to see tons of walruses in Russia lounging around, going about their lives. After centuries of evolution, their bodies are designed to manoeuvre around the Arctic ice to get where they need to be. Sadly though, the ice is in increasingly short supply.
Instead of sitting on sea ice, they haul themselves onto dry land to rest and raise their young, resulting them in being in precarious positions.

That's what we see in Our Planet where one walrus trying to get back into the sea plummets off an 80-metre cliff, hitting a few rock ledges before seemingly belly flopping into the sea.
Viewers have been quick to comment on the distressing scene, describing it as "heartbreaking."
"I really want to continue watching #ourplanet but that Walrus scene f*cking destroyed me," one person wrote.

"To those who say climate change isn't a legitimate threat I implore you to watch just the second episode of Our Planet and watch a Walrus fall off a cliff it should never have had to scale were it not for its natural habitat literally melting before them," another added.
A third added: "Literally full on sobbed to the walrus moment. This whole docuseries is so heart breaking. #OurPlanet I wish as humans we can do more."
Sophie Lanfear, who produced and directed the episode, explained just how painful it was for the crew to film.
"The walrus scenes were the hardest things I've ever had to witness or film in my career," she told the New York Times.
"I really wasn't prepared for the scale of death.

"A small group of maybe six or seven would make it down safely, and we'd all celebrate. But the vast majority do not. They basically walk themselves off the cliff.
"The walruses are used to a soft landing. Their depth perception hasn't evolved to deal with a cliff situation, nor have they evolved to work out how to get back the way they came. So it's just tragic. It's absolutely heartbreaking."
Our Planet is available to stream on Netflix now.
