We’re running out of sand says Nature. With this piccie:
OK, so, water inflow at the top remains the same, logically. Meaning that a deeper and wider channel creates slower water flow. Which leads to greater sand deposition and…..
What’s the bit I’ve got wrong here?
“Demand for sand and gravel for construction is rising faster than natural sources can sustain, so prices will soar.”
So far so good.
“Desert sand grains are too smooth to be useful, and most of the angular sand that is suitable for industry comes from rivers (less than 1% of the world’s land)”
Stopped reading economically illiterate (thanks, Tim), nothing more than appeal to the ignorant.
Even Mrs BiND understands the link.
Does this mean that the delta is at less risk of flooding?
Captain Potato demands a proper international accounting standard for sand
We have reached Peak Sand?
‘Monitor and manage this resource globally’
Dammit, we need world government!
Where my local concrete company gets its sand is no one else’s fvcking business. ESPECIALLY a global government.
Total land area is around 150 million sq km so 1% is still a pretty sizeable chunk, people have been dredging rivers (and damming them) for a hell of a long time so wonder how much of the current state can said to be natural anymore.
Bit like complaints about M4 relief road impacting natural habitat when a very large chunk of the area has sea walls and extensive drainage ditch systems already and has had for a very long time

In what sense are these people entrepreneurs? Surely they are grant farmers
Well, it’s pretty simple
– people making a profit from something make a change to a river
– therefore it is Evul Capitalism and we have a crisis.
I’m not sure exactly how the underpants gnomes get involved, but I’m sure they’re in the midst of it somehow.
They will be glad to hear that global warming is solving the problem for them: https://www.nytimes.com/interactive/2019/07/01/climate/greenland-glacier-melting-sand.html
“planting billions trees best tackle climate crisis”
That raised a snigger here. Just done my bit. A Leylandi in a bloody great pot on the terrace of my rented apartment. Should be looking good in a couple years. But how the owners of this place are going to be eventually coping with getting a fifty foot tree down umpteen flights of stairs…. Not my problem
Diogenes:
And isn’t it funny how these “regular” people the BBC finds are always government-sector workers, artist types, or pushing some sort of “socially conscious” agenda.
Sand – Madeira dredges sand from Atlantic Ocean for construction of roads, hotels, housing etc
Isn’t most UK building sand quarried? I don’t think much of it comes from rivers.
