Residents of Kandivali protested at Turzon Point against a government coastal road project (Versova-Bhayander) that threatens to destroy nearly 45,000 mangroves, which serve as the city's natural flood defence.
Protesters argue the high-speed corridor will only benefit a small, wealthy minority of car owners.
Locals reject the government's plan for compensatory afforestation inland, asserting that planting trees elsewhere cannot replace the unique coastal protection.
