Time is running out for sand
Sand and gravel are being used and extracted a lot faster then it can be replaced as of now. Sand is one of the key ingredient of modern life but yet no one knows how much is being mined and how much of it is left. From the glass bottle you drink from to the computer you work, sand is there. Their is about 32-50 billion tones of sand used each year, mainly for the use of concrete, glass and electronics. As of right now China, India and Africa are the ones that are in demand for sand. Mining speeds up the process of erosion as you can see with the picture I am showing. If we are not careful, it can get worse. -Ryan Wilburn

This is really interesting and informational. I never realized that we used sand for so many things.
