I recall on my first trip to Thailand in 2015, asking my lady friend, why are there mountains of rubbish at the side of many houses? Why are there appliances, bed parts, tires, PLASTIC BAGS in the creeks and rivers? Why do your country people toss their garbage beside the street bins instead of in the bin?
And 8 years later, it's only gotten worse, not better. No doubt, this must apall many tourists, as it did me.
