Last month, 12-year-old environment activist Riddhima Pandey posted a letter on her social media account, addressing Prime Minister Narendra Modi about her worst nightmare of going to school with an oxygen cylinder. The Haridwar-based eco warrior’s concerns over growing air pollution had become a talking point on social media as she found support from diverse sections of netizens for taking a stand on the issue. Social media—especially Twitter and Facebook—has emerged as the new platform for activists and common citizens to highlight an issue which impacts the lives of all.
