Is it true that the world is running out of sand to produce concrete, and if so, why is that?
In: 92
Like many resources, we are running out of the cheap and easily accessible versions.
People will naturally go for the “low hanging fruit”, taking what’s there for the sake of immediacy. But this supply isn’t infinite. We know how to make the resources, but often its easier just to pick it from the environment. Enough time and usage has passed that this easy resource has depleted, and can’t be replenished by natural cycles in our lifetime.
