Most people don't know this but the state is selling the Bay's dwindling sand -- so that for-profit companies can turn it into concrete.

Dredging and coastal #sandmining are responsible for a great loss of organisms and lead to other #ecological impacts like noise pollution, chemical #pollution and greenhouse gas emissions. At the same time there is no global agreement to regulate the mining of ocean sand. In terms of governing sand often local administrations are responsible and a monitoring of legal and illegal sand mining activities is left to voluntary initiatives. (5)
