Environmental activists formed a human chain at Marine Drive in south Mumbai Saturday to protest tree-cutting in the city for the ongoing Metro rail construction. They also demanded that political parties include environmental issues in their manifestos for the Lok Sabha elections.

"This chain is the city's way of declaring that its citizens will not vote for any party that does not address environmental concerns in its manifesto for Lok Sabha elections," said Amrita Bhattacharjee, a senior member of the Arey Conservation Group (ACG).
