To put pressure on the Government to declare a period of emergency to address issues relating to climate change and global warming, the Prerana Green Army will stage a demonstration here from 10 am to 12 pm on Sunday. Common people, painters, dancers, film actors, litterateurs and politicians will participate in the demonstration. They will stand on the roads and seek declaration of an ‘emergency’ against climate change and global warming. Prerana International Green Army commander-in-chief and former MLA Dillip Srichandan informed this at a Press meet here on Saturday.
