Project Vesta – Mitigating climate change with green sand beaches
“To carry out this plan, it will take a volume of 7 cubic miles of olivine rock placed on 2% of the world high-energy, tropical shelf-seas each year.”To put this in perspective, the global annual oil production is about 1 cubic mile [1], and concrete production is about half a cubic mile [2], [3] (4.4 BN tons at 2.4 t/m3 = 1.83 cubic km = 0.44 cubic miles)[1]https://en.m.wikipedia.org/wiki/Cubic_mile_of_oil[2]https://archpaper.com/2019/01/concrete-production-eight-perc...[3]https://hypertextbook.com/facts/1999/KatrinaJones.shtml
