It also destabilizes the ground and causes the failure of bridges, dikes, and roads. All of these destructive effects of sand mining ultimately lead to the loss of fertile land and property. ![]() By removing too much sediment from rivers, sand mining also leads to the erosion and shrinking of river banks. Although this balance is naturally maintained, humans interfere causes excessive erosion and thus the retreat of beaches. Sea beaches are usually formed by the balanced action of depositional and erosional forces. Unregulated mining of large volumes of sand along beaches leads to their erosion. These adverse impacts of sand mining are explained below. Such activities have a negative effect on the surrounding ecosystem.

These high levels of demand have often led to the use of unsustainable sand extraction processes and illegal sand mining. The sand can also be used as an abrasive or can be mixed with salt and applied to icy roads to reduce the melting point of ice.Īs populations grow and rates of urbanization increase, the demand for sand needed in construction also increases. The extracted sand can be used for various types of manufacturing, such as concrete used in the construction of buildings and other structures. ![]() Sand mining is the process of extracting sand from an open pit, sea beaches, rivers and ocean beds, river banks, deltas, or inland dunes.
