The Lalbagh Botanical Garden in Bengaluru is the city's oldest and largest green lung - a place that replenishes the crowded IT hub with fresh air. Close to the garden's main gate is an ancient rock topped by a tower built by the King Kempe Gowda centuries ago, to mark what he expected to be the limit of Bengaluru. But this breathing space has borne the brunt of change. Mounds of garbage cover the area. Citizens are disappointed they don't have a clean, green place to themselves in the so-called "Garden City".
