Don't know what I found more interesting... The content of the video or the fact that Simon had time to go mountain biking between hosting 100 YouTube channels

Danny, this is your chance bro, he's down an arm, he can't put up much of a fight! #FreeDanny

[rogueviking]

Poor Simon broke his collar bone flogging Danny for longer intros. Allegedly. Heal quickly, Legend!

[thcdreams]

Simon broke his arm fighting off a version of Simon invading our timeline. He ran out of channels to create and wanted to create one within our universe.

This project gives me a glimmer of hope for humanity. Thank you Simon.

Do one on the the Great Man Made River in libya which cost over 20 billion and pumps water from the worlds largest ancient aquifer which has 150000 cubic km of ground water (more water than the nile river discharges in 500 years)

[MrJjones]

Obviously he broke his collar bone trying to prevent Danny's escape

[dlerious]

One of the most amazing projects I have heard over the years, I say any progress is a way to a brighter and greener future and a greener africa

Simon: The biggest living organism

The Boreal forest: Am I joke to you?

[busydadscooking]

I lived in Ghana's Northern Region briefly in year ~2001. It was hot, and dry, and visibly very like many of the videos you showed - red dirt, some-but-infrequent trees, dry farming and occasionally a water source. It was an unpleasant and challenging place for anyone to live a self-sufficient lifestyle but that's NOT EVEN IN the Sahel which is further north yet ...

Even if it doesn't reach the goals, it's certainly better than doing nothing at all or trying to stubbornly ignore the issue

[itsapittie]

Okay, so it hasn't gone exactly in the direction originally envisioned. It has accomplished a lot and instead of denigrating it for not achieving its goal, we should be building upon what has been accomplished. In reality, very few truly "mega" projects in history have ultimately turned out as they were first envisioned.

Standard forestry practice to plant 5 saplings for each tree felled, a feature which at least one toilet roll manufacturer has used to promote their green credentials !
The 5 become one as death and thinning take place to leave one adult/ mature tree to be felled before the process starts again.
A broken clavicle is a painful cycling right of passage!

[thelamegoat]

Nice I'm trying to plant out most off my 53 Acer farm in native plants for the bird's and native animals growing back the forest in Tasmania Australia

[Fortunes.Fool.]

My last mountain bike crashed involved a deer, a concussion, a long walk home, and no real memory of what happened. Always wear your helmets, kids. I'd be brain dead without my MIPS helmet.

Not quite Sudan, but when I was 25 I went to Egypt and met a man of similar age while in the South; I remember asking him if it ever rained there, and his response was "yes, it rains, I remember it raining once" ...ONCE in his lifetime's memory he could remember rain! was a big eye-opener for me

[jetsons]

Funny, Millions of years ago the Sahara was under water and just about "5000?" years ago it was a lush land with lots of rain. The earth naturally wobbles, it's called axial precession and this has a effect on the seasons and how glaciers shrink and grow over thousands of years. Just learned about it after watching this video. Hope the "wall" helps. Thanks for

They brought Cactus and Mesquite from the Americas which have done great alongside Agave that was also brought over. The Agave is liked but the locals complain about the spines of the other two. They want to eliminate them but are often reluctant because they are the only green plants to feed livestock during droughts.

How does Simon have time for mountian biking? Surely managing the amount of channels he is involved in is a mega project in itself

[Chris-opyt]

you dont chop down a fully grown tree and graft something on top. that is not how grafting is done or used for firewood.
grafting main objective is to use vigorous and disease resistant rootstock of a young sapling, to graft a normally less well rooted plant on top. sometimes it's done to produce smaller maximum height trees of choice on top, by way of using dwarfing rootstock.
i have proper dwarf rootstock (M27) fruit trees, which will not grow bigger than 2.5m.
