Siliguri, Jan 28 (ANI): In a bid to raise awareness about polluted rivers in the West Bengal, a bike rally was organised. As many as 15 bikers with physically and mentality challenged boys of Anubhab, a non-governmental organisation that works for disabled children in Darjeeling, as pillion riders began the rally from Siliguri to Digha city. They will cover more than 750 kilometres, taking three days and four nights to complete their journey. Talking about the aim of the rally, secretary of Anubhab said they wanted to educate people about the benefits of clean water. Water is often regarded as a mere input for other activities rather than a resource to be used wisely and sustainably, experts say.
