To me that blows my mind, not because of viewing the outside as trash, but being content with living in trash. To me the observation, that the outside is a giant trash, would give me a desire to order it.
Its plain old apathy and no sense of responsibility or shared ownership. Outside is just something you share with other 1.4 billion people of the country.
The cycle usually goes like one idiot starts throwing trash, other idiots start adding their trash too, few weeks/months govt workers do a bare minimum job of clean-up, repeat.
it is not so simple of a problem with clear cut solution.
We don't need alien tech to solve these, it's 100% an education issue.
