Why people don't have Civic sense

I think the lack of basic civic sense among most of the population is due to the crowd mentality. People do it because everyone else is doing it. It's easier to throw garbage on the road and do other things that make our country look dirty, rather than not doing it and taking responsibility. Why we Indians suddenly become so responsible in foreign countries? Even in South Delhi people suddenly have basic sense but as soon as they enter East Delhi they are back to normal lol Even the new generations, Millennials and Gen Z, who are more educated than the previous generations, haven’t shown much improvement in this year. To be honest, I don't even think it's an education issue. I'm not a graduate, but I haven't thrown anything on the road, in a river, or anywhere else in the past 10-15 years. I used to do that in childhood, but without anyone telling me, I stopped doing it in my teenage years. Why don’t we Indians have basic civic sense? (Not throwing garbage in public areas, on property, or in rivers, or urinating and spitting pan or gutka on the walls and so much more What will it take for people to stop this behavior?
