Bald and Bankrupt (and his secondary channel Daily Bald)
Harald Baldr
ADV China
All 3 channels are similar in that they explore parts of the world you don’t see very often. Bald and Bankrupt spends a lot of his time in Russia or countries under former Soviet rule. I recently got into Harald Baldr as he put up a series where he was trekking through Himalayan villages.
ADV China is run by a guy from the US and one from South Africa who lived in and explored China for several years before leaving recently and going other places. It was pretty fascinating watching their attitude change on China over the years to the point they felt like they needed to move their families out of China (both married a Chinese woman) because of how the country has changed.
Nature Bats Last - Dr. Guy McPherson. Controversial professor from U of Arizona that uses peer reviewed scientific literature to make the case we're already in the midst of earth's 8th mass extinction and that runaway feedback loops have already been loosed which will kill everything on the planet by 2025.
Itchy boots - girl riding a motorcycle all over the world, totally alone. Only cameras are on her helmet or one she is holding. Started watching she was in Russia. Last year, Africa. This year riding from South America to Alaska. And she always takes roads that are nothing more than trails.
The History Guy
Mr. Ballen
Techmoan (not what it sounds like, LOL He explores technology from days gone by. A department store MUZAK system for instance...)
Grim Reapers (DCS gaming group that do absurd battle scenarios. A modern US Aircraft Carrier against the entire Japanese carrier group at the Battle of Midway etc. LOL The narration is hilarious)
Nope. You just hit the Subscribe button, if there is one (meaning they have a "channel") then, in the left margin of YT you can see the stuff you're subscribed to.
