Sand Wars (2015) Our civilisation is built on sand. We have used so much of it that it has become a scarce commodity, worth stealing and smuggling. Almost all land-based sources have been used up. Australia exports huge quantities of it. I don’t know if Canada does, but I wouldn’t be surprised. This documentary shows that removing sand from beaches and the sea floor is causing unexpected and dangerous consequences. You can find the doc here:

Watch it. Sand is an example of how our taking the environment for granted prevents us from seeing what we are doing. “Selective inattention” is the psychological term for this phenomenon. ***
