Question
[110]. Passage: River dolphins navigate murky water by echolocation, but dams, noise, fishing nets and pollution fragment their habitat and reduce prey. A dolphin that cannot move between river stretches cannot breed widely, and calves are vulnerable to entanglement. Protection requires more than a sanctuary on paper: maintaining river flow, reducing net entanglement, controlling sand mining near breeding pools, and involving fishing communities as monitors. Where fishers report sightings and rescue entangled animals, conservation gains eyes on the river that officials alone cannot provide. What is the main idea of the passage?
Option 1 : River dolphin conservation needs flow, net control, habitat protection and fisher participation, not a paper sanctuary alone.
