The Supreme Court has issued notice to the Centre and all the state governments on a plea seeking complete ban on use of plastic bags in the country. A bench headed by Justice G S Singhvi also impleaded all the plastic manufacturing companies in the case. It also sought the government's response to put in place a proper mechanism for disposal of used plastic bags. The apex court yesterday passed the order on a PIL filed by some NGOs, seeking its direction to government to ban the use of plastic bags. The NGOs had alleged that plastic bags are not disposed properly and are eaten by animals which get stuck in their stomach. The bench observed that most of the lakes and urban drain systems are choking because of plastic bags. It said that the issue raised is important to all human beings.
