One other thing about concrete that gets glossed over a lot is that it requires sand dredged up from riverbeds and other places where it is water tumbled. Wind tumbled sand, like what you find in deserts such as the Sahara, is unsuitable due to its smooth shape.
Demand for concrete in construction is contributing to erosion of riverbanks and other habitat destruction in this way.
