Bank erosion
Decline in water table
Loss of aquatic life
All of the above
Answer is Right!
Answer is Wrong!
The correct answer is: d) All of the above
Sand mining in riverbeds can lead to:
- Bank erosion. When sand is removed from a riverbed, the river loses its natural buffer against erosion. This can lead to the collapse of riverbanks, which can damage property and infrastructure, and increase the risk of flooding.
- Decline in water table. Sand is an important part of the water cycle. It helps to filter water and prevent it from seeping into the ground. When sand is removed from a riverbed, it can lead to a decline in the water table, which can have a negative impact on ecosystems and human water supplies.
- Loss of aquatic life. Sand is an important habitat for many aquatic animals. When sand is removed from a riverbed, it can destroy these habitats and disrupt the food chain. This can lead to the loss of aquatic life, including fish, shellfish, and other invertebrates.
Sand mining is a major environmental problem that can have a devastating impact on river ecosystems. It is important to be aware of the risks of sand mining and to support efforts to protect riverbeds from this destructive practice.
