River sand mining is harmful to the ecosystem because it decreases groundwater levels and dries up river water. Owing to the dragging of sand from the river, the water table level drops, and tree roots may be unable to obtain water in the absence of sand. In the absence of sand, river water evaporates due to direct su…
