With the BMC inviting suggestions and objections to removing 2,703 trees at Aarey Milk Colony to pave way for construction of the car depot for the Colaba-Bandra-Seepz Metro line-3, nature lovers and city-based green activists have launched several online petitions to garner support against the move. They are of the opinion that at least 20,000 people would file their suggestions and objections before the last date for submission (July 8).

On July 2, environment lover Nirali Vaidya started an online petition – Mumbai's climate and ecology in danger. Till date the petition has received 186,711 signatures. The petitioner has even appealed to Maharashtra Chief Minister Devendra Fadnavis, Prime Minister Narendra Modi, NGT, SC, Justice Dipak Misra, JICA India and JICA Tokyo to help save the trees.
