Every morning when he goes out for a walk, 62-year-old Paarol Rajan stops to collect plastic bottles on his 2 km route. Despite the criticism from the villagers, he is cleaning up the Chemancheri Village of Kerala in a unique way called ‘Plalking’. He started this exercise 4 months ago, when he realised plastics were choking the drains and adding to the flooding in Kerala villages.
