I heard on NPR news this morning that there is a huge global shortage of sand because of construction and silicon chips. I wonder if your project considers sand as part of the soils ecosystem. The report stated that the one remaining Sand Mine in California, USA, was being closed. The report stated how gangs were starting to take over areas where fights were breaking out over sand, like in India and Indonesia.
Anyhow, I wonder if you included this sand shortage in the scope of your project.
