Tweet, or use your feet. That's how Sunday can be summed up in terms of the 'Save Aarey' campaign. While around 3,000 people, unfazed by the rain, turned up for the 'Save Aarey' march organised by the Aam Aadmi Party (AAP) along with citizens groups, NGOs, local adivasis and concerned Mumbaikars, social media sites started buzzing with #SaveAarey in the evening.

Did rain affect the march?The march continued with torch lights even after the sun set and youth from Dance for Democracy and Play for Change performed. Nobody seemed to notice the rain, and marched on.

What was happening online?Meanwhile, a YouTube video made by independent film professionals concerned about the issue was published and shared widely online. It featured a young girl asking if "development comes by destruction of nature". Rahul Jhunjhunwala, who administrates the group's presence on Facebook and Twitter, was also present at the march. "We have around 6,000 members. We also initiated the 'Tweet Diwas', which is slowly gaining momentum. Because of the untimely rain, some people decided to opt out of the march, but we are getting online support," said Jhunjhunwala, an architect who joined the movement in November last year.

How is AAP going to do its part?Opposing the Metro car shed and the development plan that is supposed to take considerable land from Aarey, AAP media secretary of Maharashtra Ruben Mascarenhas said that they are filing RTIs and exploring judicial options. "They are two different issues and we should notice the clandestine way in which the project is being executed. The tree authority falls under BMC, so we want to know if BMC can debate this issue. The government should first get its house in order as it is easy to pontificate solutions," he said.

How did the Twitterati react?Celebrities like Raghu Ram, Jaaved Jaaferi, Ayub Khan and Archana Puran Singh joined the march as people urged Bollywood to join the protest on Twitter. Vishal Dadlani tweeted, "Dear @Dev_Fadnavis, we need 3000 trees more than a Metro yard. You CAN'T transplant grown trees. You CAN move a yard. http://saveaarey.org/." Even though the weather and Lakhvi were trending in the city, @mumbaiheritage tweeted religiously for the movement through the day with various anecdotes from history including a picture from 1949 showing Dinker Rao Desai requesting Dr. Rajendra Prasad to declare Aarey Milk Colony open in Mumbai. It said, "In 1949, when Aarey colony was established in Goregaon (E), it measured nearly five times bigger than London's Hyde Park."
