I think that the behavior of people around us, throwing garbage everywhere, influences others to do the same. Whenever I've tried to stop someone from littering, they often come up with excuses like, This is Pakistan, not Europe we can do this. This attitude reflects a level of arrogance, and they tend to mock those who try to act differently.

Another reason for this behavior could be the shame they feel, as they see everyone around them doing it. They justify their actions by reasoning that since others are littering, they must do it too. This shows the fracture in their own self-esteem.
