I don't think one has to wait for someone to start a movement. I pick up plastic bottles whenever I see them and drop them in the nearest trash bin that is meant for plastic bottles. I am in Kerala though, which is comparatively cleaner than the rest of India(except the north-eastern states).

The Kerala government is pushing for better waste management now with more trash bins placed at public places and a state-wide effort to segregate waste at the source and collect it from homes.

Still people litter with abandon and it's hard to change ingrained habits.
