This is a significant concern for the river ecosystems and the conservation of endangered species. The summary provided is a concise statement of the problem. To expand on it, we can delve deeper into the specific impacts of sand extraction on river biodiversity, the consequences for endangered species, and potential solutions.

The summary provided is very brief and lacks context. To make it more informative, we need to understand the specific species of dolphin being discussed, the geographical location, and the impact of illegal sand mining on the dolphin’s habitat. Let’s expand on the summary and create a detailed text.

The state government has initiated several measures to curb the illegal sand mining and its associated problems. These measures include a crackdown on the powerful sand mafia, but have been largely ineffective. The government has now formulated an action plan against the illegal sand mining.

A. The Price of Sand: Fish Stocks Decline, Livelihoods Suffer
B.

Our livelihood is affected by illegal sand mining because it badly hits river fish. The illegal sand mining activities are causing a significant decline in the fish population. This decline is impacting the livelihood of people who depend on fishing for their income.

* **The impact of illegal sand mining on the Ganges dolphin:** This is the primary focus of the article. * **The importance of fish as the Ganges dolphin’s food source:** Fish provide the majority of the dolphin’s diet.

The report highlights the impact of sand mining on the riverine ecosystem, emphasizing the disruption of natural water flow, sediment deposition, and the alteration of riparian vegetation. These changes can lead to habitat fragmentation, loss of biodiversity, and a decline in the overall health of the riverine ecosystem. The report also emphasizes the role of sand mining in exacerbating the already existing threats to endangered species.

This adaptation has allowed the echolocation system to become more sophisticated and efficient, making it possible for the river dolphin to navigate and hunt in the murky waters of the Ganges and Brahmaputra rivers. The river dolphin is a highly specialized creature, adapted to its unique environment. Its body is streamlined and torpedo-shaped, allowing it to move efficiently through the water. Its skin is smooth and oily, reducing friction and allowing for effortless gliding.

The primary threats to their survival are habitat loss and degradation, pollution, and overfishing. Habitat loss and degradation are primarily caused by human activities such as dam construction, river dredging, and agricultural expansion. These activities disrupt the flow of the Ganges, impacting the dolphins’ feeding and breeding grounds.
