According to the United Nations, 75 per cent of our planet's land surface has been significantly altered by human actions. It's eye-opening for a moment but forgotten later. To address environmental damage, the UN will host a biodiversity summit tomorrow, but the day will also see the release of a new map that shows how much biodiversity our own city has. That said, it needs protection.

Helmed by citizen's collective Mumbai's Ministry of Magic in partnership with Civis, a tech company, and Waatavaran, a climate non-profit, the campaign Biodiversity by the Bay aims to create a larger climate movement fuelled by young Mumbaikars. As part of this, the map, illustrated by Rohan Chakravarty, will be released.
