This Guy Can Replace David Attenborough
In terms of those who narrate nature documentaries, David Attenborough is pretty much the king. He's the voice of every major nature film and series made in the last four decades. British, mild, pleasant, he's got it all... At 93, he's also gotten really old, and while it may be a little dark to think about it, his time is coming to an end.
Don't be downhearted over it though, his replacement is just being discovered online. He's not British. His voice isn't very pleasant either, but his mannerism and sense of humor is spot on what the world needs. It's like watching that one scene from Strange Wilderness when they narrate the goblin shark footage. So epic, he's got my vote.
