The Insanity of Sand Mining
Nature is always creating more fossil fuels and also more sand. But the rate that we're using it up is an order of magnitude, several orders of magnitude faster than the rate at which new stuff is being created. In Australia exporters are literally selling sand to Arabs because they can't use desert sand. Only slightly less crazy is here in Los Angeles where I live. We actually import sand all the way from Canada to put on our beaches as our beaches are eroding so fast.
