Not sure, I have watched plenty content on yt and read on Reddit where there are videos/talks of Indians littering even in foreign lands. Although, there probably they are forced to have accountability and may learn their lessons.
Exactly. Even I have seen videos on instagram where Indians in foreign countries are doing the same thing they do here.
Just yesterday, I saw a video where few Indians were bathing with soap in a beach/river thus contaminating that water.
Few days ago, there were red spots like gutka near the trash in London probably. So yeah, Indians are spreading their habits across the world.
