Indian student takes up plogging challenge, set to clean 30 cities across UK

An Indian environmentalist, who founded the world's first community-led plogging campaign -- an eco-movement where people pick up street litter as they jog -- is on a mission to clean up 30 cities in 30 days across the UK. Over the past year, Vivek Gurav and his team of volunteers picked up 5,000 kg of rubbish, including 3,000 kg of plastic, all while out running in Bristol.
