Approximately 20 million cubic kilometers of sand cover the Earth, primarily found in deserts, beaches, and riverbeds. Sand is a key component of many ecosystems and plays a crucial role in various geological processes. While it may seem abundant, the demand for sand for construction and industrial purposes has led to concerns about its depletion in certain regions.
