Some things I didn't know about concrete:
Concrete is now the second-most consumed substance on Earth behind only water. Thirty-three billion tons of it are used each year, making it by far the most abundant human-made material in history. To make all that, we now devour around 4 billion tons of cement each year — more than in the entire first half of the 20th century, and over a billion tons more than the food we eat annually.
