Haven’t read the entire thread yet, but I did address something similar a while back in the Pit. This hasn’t changed much since COVID.
When I did clinicals on an Indian reservation, my roommate and I went out hiking one weekend day, and we were horrified at all the litter. She said, “They consider their land sacred, and they do this? It would be like going to church and dumping your garbage there.”
I’m assuming that they put their trash on a ship, and dump it in the ocean?
When my niece was an exchange student in Indonesia in 2018, she said pretty much the same thing.
The residents of an apartment in my complex, in the next building, have a dog. How do I know this? They have piles of green plastic poop bags on their patio. 
Just walk 30 feet to the dumpster and discard them, mmmkay?
You can also tell where smokers live, or visit, because there will be butts all over the place, in one concentrated area. Like you think management can’t figure out which of 3 apartments has someone who’s doing this?
I haven’t noticed any difference in littering, etc. among the different ethnicities I’ve seen living here. It seems to be more the age of the residents; we do have a significant number of college students living here. I did briefly have a neighbor from Saudi Arabia who would put his trash out on his patio, and forget about it, and the raccoons and opossums found it and spread it about, but I attributed this to his age, not his nationality. This was during the winter, so it wasn’t like he was going outside and, like, looking at it, the way the people with the dog must do.
I am surprised to hear that “the entire Dalit narrative is a media-manufacture[d] falsehood,” and that caste and class divisions in India (not to mention the rest of the world) are fictitious.
And all these years I’d been reading about it, I’d been reading made-up stuff. Well, I guess we learn something new every day, right?
I just started Isabel Wilkerson’s Caste: The Origins of Our Discontents. It’s primarily about issues in the United States, but it looks like she touches upon the (possibly fictitious) Indian caste system as well. I’ll continue reading with your post in mind.
Interesting thread. Even before “environmentalism” became a thing, we as children 60ish years ago were raised to leave every place we visited just a little better than the way we found it.
Yes, please read that junk with a liberal helping of salt. Western writers of the ilk of Isabel have done India and her culture a great disservice by writing superficially on issues they know little and understand nothing about.
