Nearly a hundred residents of Gurugram took out a protest march on Sunday to push for safeguarding the Aravalli range, a vital ecological zone and biodiversity hotspot that's home to nearly 400 species of plants and 200 species of native and migratory birds. As many as 60,000 acres of the protected forested area is likely to become available for construction purposes soon, with the Haryana government all set to table an amendment to this effect in the ongoing assembly session.
