The
natural resource with the most consumption after water is sand. There are limited reserves today because of a building boom across the planet. A lot of the sand used in construction has been smuggled and
this causes ¾ of beaches to have erosion.
Moving sand also causes the death of many creatures picked up along with
the sand. Desert sand cannot be
used as a substitute because the grains do not hold moisture and shouldn't be mixed with concrete
for buildings. Sand is used in
fiber optic cable, mobile phone components, computer chips, glass, bridges,
sidewalks, roads, runways, toothpaste, powdered food and wine.
There
is a lot of information in this film that causes concern about the heavy use of
sand. I didn’t realize it is used
in so many varied products. I
thought sand was plentiful and that desert sand could also be used. Sand used that contains salt water can
later cause metal erosion in structures.
This can be very dangerous and cause a building to collapse.
