Our dependence on concrete is exhausting global sand supplies


China may be the biggest consumer of sand right now, but the issue is a global one. A UN report published earlier this year showed that sand extraction is far outstripping the rates at which it is replenished. According to a team of scientists who recently wrote about the topic in Science Magazine ($) and The Conversation, “Sand and gravel are now the most-extracted materials in the world”–measured by weight, they surpass fossil fuels and biomass.



Writing in Forbes, Laurie Winkless probes the far-reaching and destructive impacts of skyrocketing global sand consumption as the world's urbanizing cities demand more and more of the substance to fuel new construction.

Going beyond borders, oceans, and thinking of the continents as a continuous entity comes from this vision. Fifty years later, we face the existential threat of ecological disaster, and maybe revisiting the whole earth project seems like a way of recapturing that drive. This proposal looks at a network of towers that span across the oceans connecting the planet in a matrix that provides energy cleans the oceans and gives new chances for life to thrive. Fusion, Solar, and Hydro-power are used in this matrix with all of these being in high abundance in the ocean. The towers are also self-sufficient and mine minerals from the water as well as farm to support their communities. Research and manufacturing also feature heavily. The connections of the g
